Aaron Durbin aeb2e15428 boot_device: add call to boot_device_init()
In the program loading paths using vboot it's possible that

Commit dbeedbef (arch/x86/bootblock: Link in object files selected with

Aaron Durbin 75c51d9af1 x86: add standalone verstage support
To support x86 verstage one needs a working buffer for
vboot. That buffer resides in the cache-as-ram region
which persists across verstage and romstage. The current
assumption is that verstage brings cache-as-ram up
and romstage tears cache-as-ram down. The timestamp,
cbmem console, and the vboot work buffer are persistent
through in both romstage and verstage. The vboot
work buffer as well as the cbmem console are permanently
destroyed once cache-as-ram is torn down. The timestamp
region is migrated. When verstage is enabled the assumption
is that _start is the romstage entry point. It's currently
expected that the chipset provides the entry point to
romstage when verstage is employed. Also, the car_var_*()
APIs use direct access when in verstage since its expected
verstage does not tear down cache-as-ram. Lastly, supporting
files were added to verstage-y such that an x86 verstage
will build and link.

Aaron Durbin d972f78e75 linking: link bootblock.elf with .data and .bss sections again
Currently coreboot expects the loader to clear the bss section
for all stages. i.e. stages don't clear their own bss. On ARM
SoCs the BootROM would be responsible for this. To do that
one needs to include the bss section data (all zeros) in the
bootblock.bin file. This was previously being attempted by
keeping the .bss info in the .data section because objcopy
happened zero out non-file allocated data section data.

Instead go back to linking bootblock with the bss section
but mark the bss section as loadable allocatable data. That
way it will be included in the binary properly when objcopy
-O binary is emplyed. Also do the same for the data section
in the case of no non-zero object values are in the data
section.

Without this change the trick of including .bss in .data
was not working when there wasn't a non-zero value object
in the data section.

BUG=None
BRANCH=None
TEST=Built emulation/qemu-armv7 and noted bootblock.bin contains

To start alleviating that the way ramstage is linked is partially

to link stages by deferring to per-stage architectural overrides.
The previous ramstage.ld is no longer required.

Note that this change doesn't handle RELOCATABLE_RAMSTAGE

can be achieved, but for the time being that's being left out.

Some of the Chrome OS boards were directly calling vboot
called in some form after contorting around #ifdef preprocessor
macros. The reasoning is that Chrome OS doesn't always do display
initialization during startup. It's runtime dependent. While
this is a requirement that doesn't mean vboot functions should be
sprinkled around in the mainboard and chipset code. Instead provide
one function, display_init_required(), that provides the policy
for determining display initialization action. For Chrome OS
devices this function honors vboot_skip_display_init() and all
other configurations default to initializing display.

Aaron Durbin c49014e750 timestamp: add tick frequency to exported table
Add the timestamp tick frequency within the timestamp table so
the cbmem utility doesn't try to figure it out on its own. Those
paths still exist for x86 systems which don't provide tsc_freq_mhz().
All other non-x86 systems use the monotonic timer which has a 1us
granularity or 1MHz.

One of the main reasons is that Linux is reporting
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq as the true
turbo frequency on turbo enables machines. This change also fixes

Julius Werner 8d8799a33a arm, arm64, mips: Add rough static stack size checks with -Wstack-usage
We've seen an increasing need to reduce stack sizes more and more for
space reasons, and it's always guesswork because no one has a good idea
how little is too litte. We now have boards with 3K and 2K stacks, and
old pieces of common code often allocate large temporary buffers that
would lead to very dangerous and hard to detect bugs when someone
eventually tries to use them on one of those.

This patch tries improve this situation at least a bit by declaring 2K
as the minimum stack size all of coreboot code should work with. It
checks all function frames with -Wstack-usage=1536 to make sure we don't
allocate more than 1.5K in a single buffer. This is of course not a
perfect test, but it should catch the most common situation of declaring
a single, large buffer in some close-to-leaf function (with the
assumption that 0.5K is hopefully enough for all the "normal" functions
above that).

Change one example where we were a bit overzealous and put a 1K buffer
into BSS back to stack allocation, since it actually conforms to this
new assumption and frees up another kilobyte of that highly sought-after
verstage space. Not touching x86 with any of this since it's lack of
__PRE_RAM__ BSS often requires it to allocate way more on the stack than
would usually be considered sane.

BUG=None
TEST=Compiled Cosmos, Daisy, Falco, Blaze, Pit, Storm, Urara and Pinky,

While running ramstage with the EARLY_CBMEM_INIT config the timestamp
cache was re-initialized and subsequently used. The result was that
the ramstage timestamps would be dropped from cbmem.  The reason
is that the ramstage timestamps perpetually lived in ramstage BSS
never getting sync'd back into cbmem. The fix is to honor the
cache state in ramstage in the timestamp_init() path.

Also, make cache_state a fixed bit width to allow for different
architectures across the pre-ramstage stages.

Duncan Laurie a51815119f hardwaremain: Move init_timer() call to before console init
The 8250 MMIO uart driver calls udelay, and if that is the first
call then it will also call printk in init_timer() which can result
in a deadlock trying to acquire the console lock.

There are a few options to prevent this:
1) remove the printk in init_timer which removes a useful debug message
2) change the udelay() to cpu_relax() in uart8250mem.c
3- move the init_timer() call in ramstage main() to be called earlier

Since hardwaremain.c:main() already has an explicit call to init_timer()
on x86 it is an easy change to move this to happen before the console
is initialized.

Kyösti Mälkki 4fbac46524 cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() API
Squashed and adjusted two changes from chromium.git. Covers
CBMEM init for ROMTAGE and RAMSTAGE.

cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API

There are several use cases for performing a certain task when CBMEM is
first set up (usually to migrate some data into it that was previously
kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them
differently: timestamp migration is called explicitly from
cbmem_initialize(), certain x86-chipset-specific tasks use the
CAR_MIGRATION() macro to register a hook, and the CBMEM console is
migrated through a direct call from romstage (on non-x86 and SandyBridge
boards).

This patch decouples the CAR_MIGRATION() hook mechanism from
cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer
description of what it really does. All of the above use cases are
ported to this new, consistent model, allowing us to have one less line

cbmem: Extend hooks to ramstage, fix timestamp synching

Commit 7dd5bbd71 (cbmem: Unify random on-CBMEM-init tasks under common
CBMEM_INIT_HOOK() API) inadvertently broke ramstage timestamps since
timestamp_sync() was no longer called there. Oops.

This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism
to the cbmem_initialize() call in ramstage. The macro is split into
explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as
possible and prevent surprises (although just using a single macro and
relying on the Makefiles to link an object into all appropriate stages
would also work).

This allows us to get rid of the explicit cbmemc_reinit() in ramstage
(which I somehow accounted for in the last patch without realizing that
timestamps work exactly the same way...), and replace the older and less
flexible cbmem_arch_init() mechanism.

Also added a size assertion for the pre-RAM CBMEM console to memlayout
that could prevent a very unlikely buffer overflow I just noticed.

Julius Werner 7a8a4ab1d8 lib: Unify log2() and related functions
This patch adds a few bit counting functions that are commonly needed
for certain register calculations. We previously had a log2()
implementation already, but it was awkwardly split between some C code
that's only available in ramstage and an optimized x86-specific
implementation in pre-RAM that prevented other archs from pulling it
into earlier stages.

Using __builtin_clz() as the baseline allows GCC to inline optimized
assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and
to perform constant-folding if possible. What was previously named log2f
on pre-RAM x86 is now ffs, since that's the standard name for that
operation and I honestly don't have the slightest idea how it could've
ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm
with Float result, whereas the Find First Set operation has no direct
correlation to logarithms that I know of). Make ffs result 0-based
instead of the POSIX standard's 1-based since that is consistent with
clz, log2 and the former log2f, and generally closer to what you want
for most applications (a value that can directly be used as a shift to
reach the found bit). Call it __ffs() instead of ffs() to avoid problems
when importing code, since that's what Linux uses for the 0-based
operation.

BUG=None
TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new

Aaron Durbin 899d13d0df cbfs: new API and better program loading
A new CBFS API is introduced to allow making CBFS access
easier for providing multiple CBFS sources. That is achieved
by decoupling the cbfs source from a CBFS file. A CBFS
source is described by a descriptor. It contains the necessary
properties for walking a CBFS to locate a file. The CBFS
file is then decoupled from the CBFS descriptor in that it's
no longer needed to access the contents of the file.

All of this is accomplished using the regions infrastructure
by repsenting CBFS sources and files as region_devices. Because
region_devices can be chained together forming subregions this
allows one to decouple a CBFS source from a file. This also allows
one to provide CBFS files that came from other sources for
payload and/or stage loading.

The program loading takes advantage of those very properties
by allowing multiple sources for locating a program. Because of
this we can reduce the overhead of loading programs because
it's all done in the common code paths. Only locating the
program is per source.

Intermediate linking may distort linker behavior (in particular related to

object files', and ideally makes the linker more predictable.

Using --whole-archive, the linker doesn't optimize out object files just
because their symbols were already provided by weak versions. However it
shouldn't be used for libgcc, because that one has some unexpected side-effects.

These create link time conflicts when trying to link both the

so separate "stage" parts (that allow things to run) from "library" parts
(that contain the vboot specifics).

By design, the imd library still provdes dynamic growth so that

the reduced fragmentation and reduced memory usage.

track memory regions by assigning ids to each region. The implementation
is a direct descendant of dynamic cbmem. The intent is to replace
the existing mechanisms which do similar things: dynamic cbmem, stage
cache, etc.

Differences between dynamic cbmem and imd:
- All structures/objects are relative to one another. There
  are no absolute pointers serialized to memory.
- Allow limiting the size of the idm. i.e. provide a maximum
  memory usage.
- Allow setting the size of the root structure which allows
  control of the number of allocations to track.

Vadim Bendebury 6bfabce33b cbfs: look for CBFS header in a predefined place
This patch introduces a new option (CONFIG_MULTIPLE_CBFS_INSTANCES) to
allow multiple CBFS instances in the bootrom.

When the new option is enabled, the code running on the target
controls which CBFS instance is used. Since all other then header CBFS
structures use relative addressing, the only value which needs
explicit setting is the offset of the CBFS header in the bootrom.

This patch adds a facility to set the CBFS header offset. The offset
value of zero means default. i.e. the CBFS initialization code still
discovers the offset through the value saved at the top of the ROM.

three properties of flash to achieve that:
- The size of the flash device
- The sector size, i.e., the granularity of erase
- The command used for erase
The patch sends the parameters through coreboot and then libpayload.
The patch also includes a minor refactoring of the flash erase code.
Parameters are sent up for just one flash device. If multiple SPI
flash devices are probed, the second one will "win" and its
parameters will be sent up to the payload.

TEST=Observed parameters to be passed up to depthcharge through
libpayload and be used to correctly initialize flash and do an erase.
TEST=Winbond and Gigadevices spi flash drivers compile with the changes;
others don't, for seemingly unrelated reasons.

This adds a 10us delay in between (re-)configuring and reading

Julius Werner a43db197f3 arm: Fix checkstack() to use correct stack size
checkstack() runs at the end of ramstage to warn about stack overflows,
and it assumes that CONFIG_STACK_SIZE is always the size of the stack to
check. This is only true for systems that bring up multiprocessing in
ramstage and assign a separate stack for each core, like x86 and ARM64.
Other architectures like ARM and MIPS (for now) don't touch secondary
CPUs at all and currently don't look like they'll ever need to, so they
generally stay on the same (SRAM-based) stack they have been on since
their bootblock.

This patch tries to model that difference by making these architectures
explicitly set CONFIG_STACK_SIZE to zero, and using that as a cue to
assume the whole (_estack - _stack) area in checkstack() instead. Also
adds a BUG() to the stack overflow check, since that is currently just
as non-fatal as the BIOS_ERR message (despite the incorrect "SYSTEM
HALTED" output) but a little more easy to spot. Such a serious failure
should not drown out in all the normal random pieces of lower case boot
spam (also, I was intending to eventually have a look at assert() and
BUG() to hopefully make them a little more useful/noticeable if I ever
find the time for it).

Julius Werner a7d924412a timestamps: You can never have enough of them!
Now that we have timestamps in pre-RAM stages, let's actually make use
of them. This patch adds several timestamps to both the bootblock and
especially the verstage to allow more fine-grained boot time tracking.

Some of the introduced timestamps can appear more than once per boot.
This doesn't seem to be a problem for both coreboot and the cbmem
utility, and the context makes it clear which operation was timestamped
at what point.

Also simplifies cbmem's timestamp printing routine a bit, fixing a
display bug when a timestamp had a section of exactly ",000," in it
(e.g. 1,000,185).

Julius Werner 44cf870cb0 timer: Reestablish init_timer(), consolidate timer initialization calls
We have known for a while that the old x86 model of calling init_timer()
in ramstage doesn't make sense on other archs (and is questionable in
general), and finally removed it with CL:219719. However, now timer
initialization is completely buried in the platform code, and it's hard
to ensure it is done in time to set up timestamps. For three out of four
non-x86 SoC vendors we have brought up for now, the timers need some
kind of SoC-specific initialization.

This patch reintroduces init_timer() as a weak function that can be
overridden by platform code. The call in ramstage is restricted to x86
(and should probably eventually be removed from there as well), and
other archs should call them at the earliest reasonable point in their
bootblock. (Only changing arm for now since arm64 and mips bootblocks
are still in very early state and should sync up to features in arm once
their requirements are better understood.) This allows us to move
timestamp_init() into arch code, so that we can rely on timestamps
being available at a well-defined point and initialize our base value as
early as possible. (Platforms who know that their timers start at zero
can still safely call timestamp_init(0) again from platform code.)

Julius Werner efcee767de CBFS: Automate ROM image layout and remove hardcoded offsets
Non-x86 boards currently need to hardcode the position of their CBFS
master header in a Kconfig. This is very brittle because it is usually
put in between the bootblock and the first CBFS entry, without any
checks to guarantee that it won't overlap either of those. It is not fun
to debug random failures that move and disappear with tiny alignment
changes because someone decided to write "ORBC1112" over some part of
your data section (in a way that is not visible in the symbolized .elf
binaries, only in the final image). This patch seeks to prevent those
issues and reduce the need for manual configuration by making the image
layout a completely automated part of cbfstool.

Since automated placement of the CBFS header means we can no longer
hardcode its position into coreboot, this patch takes the existing x86
solution of placing a pointer to the header at the very end of the
CBFS-managed section of the ROM and generalizes it to all architectures.
This is now even possible with the read-only/read-write split in
ChromeOS, since coreboot knows how large that section is from the
CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be
changed on systems that place other data next to coreboot/CBFS in ROM).

Also adds a feature to cbfstool that makes the -B (bootblock file name)
argument on image creation optional, since we have recently found valid
use cases for CBFS images that are not the first boot medium of the
device (instead opened by an earlier bootloader that can already
interpret CBFS) and therefore don't really need a bootblock.

Julius Werner 886d29bcd8 gpio: Remove non-ternary tristate mode, make ternaries easier
The function to read board IDs from tristate GPIOs currently supports
two output modes: a normal base-3 integer, or a custom format where
every two bits represent one tristate pin. Each board decides which
representation to use on its own, which is inconsistent and provides
another possible gotcha to trip over when reading unfamiliar code.

The two-bits-per-pin format creates the additional problem that a
complete list of IDs (such as some boards use to build board-ID tables)
necessarily has "holes" in them (since 0b11 does not correspond to a
possible pin state), which makes them extremely tricky to write, read
and expand. It's also very unintuitive in my opinion, although it was
intended to make it easier to read individual pin states from a hex
representation.

This patch switches all boards over to base-3 and removes the other
format to improve consistency. The tristate reading function will just
print the pin states as they are read to make it easier to debug them,
and we add a new BASE3() macro that can generate ternary numbers from
pin states. Also change the order of all static initializers of board ID
pin lists to write the most significant bit first, hoping that this can
help clear up confusion about the endianness of the pins.

Julius Werner eaa9c4596b gpio: Extend common GPIO header, simplify function names
We've had gpiolib.h which defines a few common GPIO access functions for
a while, but it wasn't really complete. This patch adds the missing
gpio_output() function, and also renames the unwieldy
gpio_get_in_value() and gpio_set_out_value() to the much easier to
handle gpio_get() and gpio_set(). The header is renamed to the simpler
gpio.h while we're at it (there was never really anything "lib" about
it, and it was presumably just chosen due to the IPQ806x include/
conflict problem that is now resolved).

It also moves the definition of gpio_t into SoC-specific code, so that
different implementations are free to encode their platform-specific
GPIO parameters in those 4 bytes in the most convenient way (such as the
rk3288 with a bitfield struct). Every SoC intending to use this common
API should supply a <soc/gpio.h> that typedefs gpio_t to a type at most
4 bytes in length. Files accessing the API only need to include <gpio.h>
which may pull in additional things (like a gpio_t creation macro) from
<soc/gpio.h> on its own.

For now the API is still only used on non-x86 SoCs. Whether it makes
sense to expand it to x86 as well should be separately evaluated at a
later point (by someone who understands those systems better). Also,
Exynos retains its old, incompatible GPIO API even though it would be a
prime candidate, because it's currently just not worth the effort.

Aaron Durbin b0d8f5e9cd hardwaremain: explicitly call cbmem_initialize() early
Over the course of time there have been some implicit assumptions
about cbmem being available for find() or add() operations. However,
the cbmem area was never fully recovered until entering the state
machine: BS_ON_ENTRY into BS_PRE_DEVICE. Correct this assumption
by explicitly calling cbmem_initialize() in the EARLY_CBMEM_INIT
case.

This, however, doesn't fix timestamp_init() showing an error about
not being able to allocate the timestamp table.

Julius Werner ec5e5e0db2 New mechanism to define SRAM/memory map with automatic bounds checking
This patch creates a new mechanism to define the static memory layout
(primarily in SRAM) for a given board, superseding the brittle mass of
Kconfigs that we were using before. The core part is a memlayout.ld file
in the mainboard directory (although boards are expected to just include
the SoC default in most cases), which is the primary linker script for
all stages (though not rmodules for now). It uses preprocessor macros
from <memlayout.h> to form a different valid linker script for all
stages while looking like a declarative, boilerplate-free map of memory
addresses to the programmer. Linker asserts will automatically guarantee
that the defined regions cannot overlap. Stages are defined with a
maximum size that will be enforced by the linker. The file serves to
both define and document the memory layout, so that the documentation
cannot go missing or out of date.

The mechanism is implemented for all boards in the ARM, ARM64 and MIPS
architectures, and should be extended onto all systems using SRAM in the
future. The CAR/XIP environment on x86 has very different requirements
and the layout is generally not as static, so it will stay like it is
and be unaffected by this patch (save for aligning some symbol names for
consistency and sharing the new common ramstage linker script include).

BUG=None
TEST=Booted normally and in recovery mode, checked suspend/resume and
the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and
Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies
with ToT and looked for red flags.

Ionela Voinescu 00903e5fc0 cbfs/rmodule: add architecture specific operations at stage load
Two weak functions were added so that architecture specific operations
on each segment of payload or stage can be performed.
Each architecture must define its own operations, otherwise the
behavior will default to do-nothing functions.

This patch has been updated by to fit more in line with
how program loading is currently being done. The API is the
same as the original, but all call sites to stages/payloads
have been updated. This is known to break any archs that use
rmodule loading that needs cache maintenance. That will be fixed
in a forthcoming patch. Also, the vboot paths are left as is
for easier upstreaming of the rest of the vboot patches.

Vadim Bendebury a88c919767 cbfs: support concurrent media channels properly
Coreboot generic CBFS media API does not support
multiple media access instances, but it should.

With this fix the CBFS context (memory cache for
SPI accesses) is shared among all open media access
streams. A better memory management scheme might be
required, but for now this fix allows to support
booting deptcharge and accessing VPD through two
independent CBFS media streams.

BUG=chrome-os-partner:32152
TEST=no exception is thrown when the second stream
     is opened

Vadim Bendebury 9c9c336464 Generalize revision number calculation function
Some platforms use tertiary interpretation of GPIO input state to
increase number of distinct values represented by a limited number of
GPIOs. The three states are

- external pull down (interpreted as 0)
- external pull up (1)
- not connected (2)

This has been required by Nvidia devices so far, but Exynos and
Ipq8086 platforms need this too.

This patch moves the function reading the tertiary state into the
library and exposes the necessary GPIO API functions in a new include
file. The functions are still supposed to be provided by platform
specific modules.

The function interpreting the GPIO states has been modified to allow
to interpret the state either as a true tertiary number or as a set
two bit fields.

Since linker garbage collection is not happening when building x86
targets, a new configuration option is being added to include the new
module only when needed.

Aaron Durbin 9ef9d85976 bootstate: use structure pointers for scheduling callbacks
The GCC 4.9.2 update showed that the boot_state_init_entry
structures were being padded and assumed to be aligned in to an
increased size. The bootstate scheduler for static entries,
boot_state_schedule_static_entries(), was then calculating the
wrong values within the array. To fix this just use a pointer to
the boot_state_init_entry structure that needs to be scheduled.

In addition to the previous issue noted above, the .bs_init
section was sitting in the read only portion of the image while
the fields within it need to be writable. Also, the
boot_state_schedule_static_entries() was using symbol comparison
to terminate a loop which in C can lead the compiler to always
evaluate the loop at least once since the language spec indicates
no 2 symbols can be the same value.

Julius Werner dbe0df1992 Add and consistently use wrapper macro for romstage static variables
x86 systems run their romstage as execute-in-place from flash, which
prevents them from having writable data segments. In several code pieces
that get linked into both romstage and ramstage, this has been worked
around by using a local variable and having the 'static' storage class
guarded by #ifndef __PRE_RAM__.

However, x86 is the only architecture using execute-in-place (for now),
so it does not make sense to impose the restriction globally. Rather
than fixing the #ifdef at every occurrence, this should really be
wrapped in a way that makes it easier to modify in a single place. The
chromeos/cros_vpd.c file already had a nice approach for a wrapper
macro, but unfortunately restricted it to one file... this patch moves
it to stddef.h and employs it consistently throughout coreboot.

Add CBMEM console to bootblock, except for x86. Only one of bootblock

To start with empty console log on S3 wakeup, ramstage now clears
previous contents of CBMEM buffer if there was no pre-RAM buffer.

Unify Kconfig variable naming.

Stefan Reinauer d6865222c8 misc: Drop print_ implementation from non-romcc boards
Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*.

Back in the day, like more than half a decade ago, we migrated a lot
of boards to printk, but we never cleaned up the existing code to be
consistent. Instead, we worked around the problem with a very messy
console.h (nowadays the mess is hidden in romstage_console.c and
early_print.h)

This patch cleans up the generic code pieces to use printk() on all
non-ROMCC boards.

Our two remaining ROMCC boards are fixed up in this commit:
bifferos/bifferboard and dmp/vortex86ex.

Vadim Bendebury adcb095e9e Provide a common CBFS wrapper for SPI storage
Coreboot has all necessary infrastructure to use the proper SPI flash
interface in bootblock for CBFS. This patch creates a common CBFS
wrapper which can be enabled on different platforms as required.

COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the
common CBFS interface and prevents default inclusion of all SPI chip
drivers, only explicitly configured ones will be included when the new
feature is enabled. Since the wrapper uses the same driver at all
stages, enabling the new feature will also make it necessary to
include the SPI chip drivers in bootblock and romstage images.

init_default_cbfs_media() can now be common for different platforms,
and as such is defined in the library.

BUG=none
TEST=manual
   . with this change and the rest of the patches coreboot on AP148
     comes up all the way to attempting to boot the payload (reading
     earlier stages from the SPI flash along the way).

To support parsing multiple EDID blobs, the static "decode results" flags should

This is done by packaging static variables into a structure inside decode_edid.
We also revised some functions (manufacturer_name, do_checksum) to avoid
accessing global variables directly. Extension (and detail block) parsing may
need to access and return all parsed context so we pass the whole structure to

predictable place relative to other things in the linker script. That makes it
difficult to work with as its own section because the linker will complain if
you try to move backwards as it lays out memory. If the console header is
treated as an actual blob of memory which has to be put in the image, we'd
have to predict where to put it so that it isn't before something with a lower
address or after something with a higher address. Symbols, on the other hand,
can be defined arbitrarily.

Ronald G. Minnich 9518b56ab0 intel/gma: Clarify code and use dedicated init for Google Peppy
Peppy had some issues with FUI. We decided it was time to create
peppy-specific gma.c and i915io.c files. Using yabel and the i915tool,
we generated a replay attack, then interpolated against the slippy
i915io.c to get something working.

Also, in preparation for moving code out of the mainboard gma.c to
generic driver code, we got rid of some hardcodes in the mainboard
gma.c that have no business being there. The worst were the
computation of gmch_[m,n] and it turns out that we had some
long-standing bugs related to confusion about 'bpp'. I've killed the
word bpp everywhere I could because there are at least 3 things that
correspond to bpp. We now have framebuffer, pipe, and panel bpp. The
names are long because I want to avoid all the mistakes we've all been
making in the last year :-) Sadly, that means a lot of changes not just
peppy-related, but they are simple and in a good cause.

The test pattern generation is driven by a global variable in
mainboard/peppy/gma.c.  I've found in the past that it's very useful
to have a function like this available, as one can activate it while
using a jtag debugger: halt at the right place in ramstage, set the
variable to 1, continue. It's not enough code to worry about always
including.

The last hard-codes for M and N registers are gone, and the function
to set from generic intel_dp.c code works.  To avoid screen trash on a
dev mode boot, which we liked but nobody else did :-), we now take the
time to put a pleasing background color that sort of doubles as a
power LED.

Rough timing is ramstage start is at 2.2, and dev setup is done at
3.3. These new platforms are depressingly slow to boot. Rom init alone
is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash
prompt. These CPUs are at least 10x faster and take much longer to get going.

Future work, once we get this through, is to move more functions to the
intel driver, and combine the mainboard i915io.c into the mainboard gma.c.
That separation only existed because i915io.c was generated by a tool, and it
had lots of ugliness. Most ugliness is gone.

Julius Werner b8fad3d029 arm: libpayload: Add cache coherent DMA memory definition and management
This patch adds a mechanism to set aside a region of cache-coherent
(i.e. usually uncached) virtual memory, which can be used to communicate
with DMA devices without automatic cache snooping (common on ARM)
without the need of explicit flush/invalidation instructions in the
driver code.

This works by setting aside said region in the (board-specific) page
table setup, as exemplary done in this patch for the Snow and Pit
boards. It uses a new mechanism for adding board-specific Coreboot table
entries to describe this region in an entry with the LB_DMA tag.

Libpayload's memory allocator is enhanced to be able to operate on
distinct types/regions of memory. It provides dma_malloc() and
dma_memalign() functions for use in drivers, which by default just
operate on the same heap as their traditional counterparts. However, if
the Coreboot table parsing code finds a CB_DMA section, further requests
through the dma_xxx() functions will return memory from the region
described therein instead.

Provide functionality to create dynamic classes based on program name and
architecture for which the program needs to be compiled/linked. define_class
takes program_name and arch as its arguments and adds the program_name to
classes-y to create dynamic class. Also, compiler toolset is created for the
specified arch. All the files for this program can then be added to
program_name-y += .. Ensure that define_class is called before any files are
added to the class. Check subdirs-y for order of directory inclusion.

One such example of dynamic class is rmodules. Multiple rmodules can be used
which need to be compiled for different architectures. With dynamic classes,
this is possible.

Julius Werner 586460b242 cbfs: Check return value of map() for error
The CBFS core checks the result of a media->map() operation in multiple
places for CBFS_MEDIA_INVALID_MAP_ADDRESS, suggesting that this is a
valid response. However, it ironically fails to do so when actually
mapping the CBFS file itself, which can fail on buffer-constrained
systems since the size is much larger than when mapping metadata. This
patch adds a check with an error message and a NULL pointer return for
that case to make it easier to understand this condition.

Furquan Shaikh 99ac98f7e1 Introduce stage-specific architecture for coreboot
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.

These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.

In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.

Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.

We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.

Use of CAR_GLOBAL is not safe after CAR is torn down, unless the
board properly implements EARLY_CBMEM_INIT.

Flag vulnerable boards that only do cbmem_recovery() in romstage on S3
resume and implementation with Intel FSP that invalidates cache before
we have a chance to copy the contents.

Aaron Durbin 3eb8eb7eba rmodules: use rmodtool to create rmodules
Start using the rmodtool for generating rmodules.
rmodule_link() has been changed to create 2 rules:
one for the passed in <name>, the other for creating
<name>.rmod which is an ELF file in the format of
an rmodule.

Since the header is not compiled and linked together
with an rmodule there needs to be a way of marking
which symbol is the entry point. __rmodule_entry is
the symbol used for knowing the entry point. There
was a little churn in SMM modules to ensure an
rmodule entry point symbol takes a single argument.

Aaron Durbin 06ece7de93 chromeos: provide option to dynamically allocate ram oops buffer
Fixing the location of the ram oops buffer can lead to certain
kernel and boot loaders being confused when there is a ram
reservation low in the address space. Alternatively provide
a mechanism to allocate the ram oops buffer in cbmem. As cbmem
is usually high in the address space it avoids low reservation
confusion.

The patch uncondtionally provides a GOOG9999 ACPI device with
a single memory resource describing the memory region used for
the ramoops region.

BUG=None
BRANCH=baytrail,haswell
TEST=Built and booted with and w/o dynamic ram oops. With
     the corresponding kernel change things behave correctly.

Aaron Durbin c34713d33e x86: add MIRROR_PAYLOAD_TO_RAM_BEFORE_LOADING option
Boot speeds can be sped up by mirroring the payload into
main memory before doing the actual loading. Systems that
would benefit from this are typically Intel ones whose SPI
are memory mapped. Without the SPI being cached all accesses
to the payload in SPI while being loaded result in uncacheable
accesses. Instead take advantage of the on-board SPI controller
which has an internal cache and prefetcher by copying 64-byte
cachelines using 32-bit word copies.

Divisor is a function of requested baudrate, platform-specific
reference clock and amount of oversampling done on the UART reference.
Calculate this parameter with divisor rounded to nearest integer.

When building without option_table or when there is no entry for
baud_rate, CONFIG_TTYS0_BAUD is used for default baudrate.

For OxPCIe use of 4 MHz for reference was arbitrary giving correct
divisor for 115200 but somewhat inaccurate for lower baudrates.
Actual hardware is 62500000 with 16 times oversampling.

FIXME: Field for baudrate in lb_tables is still incorrect.

Vladimir Serbinenko 4337020b95 Remove CACHE_ROM.
With the recent improvement 3d6ffe76f8,
speedup by CACHE_ROM is reduced a lot.
On the other hand this makes coreboot run out of MTRRs depending on
system configuration, hence screwing up I/O access and cache
coherency in worst cases.

CACHE_ROM requires the user to sanity check their boot output because
the feature is brittle. The working configuration is dependent on I/O
hole size, ram size, and chipset. Because of this the current
implementation can leave a system configured in an inconsistent state
leading to unexpected results such as poor performance and/or
inconsistent cache-coherency

Remove this as a buggy feature until we figure out how to do it properly
if necessary.

Aaron Durbin 0f333071ef coreboot: infrastructure for different ramstage loaders
There are 2 methods currently available in coreboot to load
ramstage from romstage: cbfs and vboot. The vboot path had
to be explicitly enabled and code needed to be added to
each chipset to support both. Additionally, many of the paths
were duplicated between the two. An additional complication
is the presence of having a relocatable ramstage which creates
another path with duplication.

To rectify this situation provide a common API through the
use of a callback to load the ramstage. The rest of the
existing logic to handle all the various cases is put in
a common place.
