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.

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.

Some SOCs (like pistachio, for instance) provide an 8250 compatible
UART, which has the same register layout, but mapped to a bus of a
different width.
Instead of adding a new driver for these controllers, it is better to
have coreboot report UART register width to libpayload, and have it
adjust the offsets accordingly when accessing the UART.

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.

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).

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.

Now that microcode has been added to blobs, use that one instead of
the one included in the tree. Microcode from the tree will be
removed in a subsequent patch. Since the microcode updates are blobs,
they belong in the blobs repository.
This change may introduce a build failure if the "Generate from tree"
microcode option is selected, but the blobs repository is not
enabled. We have to live with this for now, until microcode is moved
to blobs for all CPUs, at which point we may adjust Kconfig
accordingly.
Leave the FSP cpu alone for now, as that will need approval from
SAGE.

it's directly linked to bootblock. This allows us to avoid code

This patch adds I2C emulation in software through raw toggling of the
SDA/SCL lines. Platforms need to provide bindings to toggle their
respective I2C busses for this to work (e.g. by pinmuxing them as GPIOs,
currently only enabled for Tegra).
This is mostly useful as a debugging feature, to drive unusual states on
a bus and closely monitor the device output without the need of a bus
analyzer. It provides a few functions to "wedge" an I2C bus by aborting
a transaction at certain points, which can be used to test if a system
can correctly recover from an ill-timed reboot. However, it can also
dynamically replace the existing I2C transfer functions and drive
some/all I2C transfers on the system, which might be useful if a driver
for the actual I2C controller hardware is not (yet) available.
Based on original code by Doug Anderson <dianders@chromium.org> and
Hung-ying Tyan <tyanh@chromium.org> for the ChromeOS embedded
controller project.

ipq8064: storm: re-arrange bootblock initialization
The recent addition of the storm bootblock initialization broke
compilation of Exynos platforms. The SOC specific code needs to be
kept in the respective source files, not in the common CPU code.
As of now coreboot does not provide a separate SOC initialization API.
In general it makes sense to invoke SOC initialization from the board
initialization code, as the board knows what SOC it is running on.
Presently all what's need initialization on 8064 is the timer. This
patch adds the SOC initialization framework for 8064 and moves there
the related code.

arm: Redesign mainboard and SoC hooks for bootblock
This patch makes some slight changes to the way bootblock_cpu_init() and
bootblock_mainboard_init() are used on ARM. Experience has shown that
nearly every board needs either one or both of these hooks, so having
explicit Kconfigs for them has become unwieldy. Instead, this patch
implements them as a weak symbol that can be overridden by mainboard/SoC
code, as the more recent arm64_soc_init() is also doing.
Since the whole concept of a single "CPU" on ARM systems has kinda died
out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had
already been done on Storm/ipq806x, which is now adjusted to directly
use the generic hook.) Also add a proper license header to
bootblock_common.h that was somehow missing.
Leaving non-ARM32 architectures out for now, since they are still using
the really old and weird x86 model of directly including a file. These
architectures should also eventually be aligned with the cleaner ARM32
model as they mature.

TEST=Booted on Pinky. Compiled for Storm and confirmed in the

The new API is in use in depthcharge and is based around the "i2c_transfer"
function instead of i2c_read and i2c_write. The new function takes an array of
i2c_seg structures which represent each portion of the transfer after a start
bit and before the stop bit. If there's more than one segment, they're
seperated by repeated starts.
Some wrapper functions have also been added which make certain common
operations easy. These include reading or writing a byte from a register or
reading or writing a blob of raw data. The i2c device drivers generally use
these wrappers but can call the i2c_transfer function directly if the need
something different.
The tegra i2c driver was very similar to the one in depthcharge and was simple
to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and
replace the ones in coreboot. The Exynos 5420 driver was ported from the high
speed portion of the one in coreboot and was straightforward to port back. The
low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot
and were replaced with the depthcharge implementation.

BOOT_MEDIA_SPI_BUS is a Kconfig variable used on some ARM-based
platforms to set up CBFS media. It turns out it can also be helpful
for setting up the eventlog which is intended to reside on the same
SPI flash as CBFS. Setting it for x86 will allow us to remove an
assumption about which SPI bus is used for this flash device.
Long term this can go away as we come up with a better abstraction
for the eventlog's backing store. This is only intended to help us
get from here to there.

Old routine copied all of CAR region as-is right below CONFIG_RAMTOP.
Most of this region was reserved to interleave AP CPU address spaces
and unused on BSP CPU. The only part of CAR region requiring a copy
in RAM is the sysinfo structure.
Improved routine changes this as follows:
A region of size 'backup_size' below CONFIG_RAMTOP is cleared. In
case of S3 resume, OS context from this region is first copied to
high memory (CBMEM_ID_RESUME).
At stack switch, CAR stack is discarded. Top of the stack for BSP
is located at 'CONFIG_RAMTOP - car_size' for the remaining part
of the romstage. This region is part of 'backup_size' and was zeroed
before the switch took place.
Before CAR is torn down the region of CAR_GLOBALS (and CAR_CBMEM),
including the relevant sysinfo data for AP nodes memory training,
is copied at 'CONFIG_RAMTOP - car_size'.
NOTE: While CAR_GLOBAL variables are recovered, there are currently
no means to calculate their offsets in RAM.
NOTE: Boards with multiple CPU packages are likely already broken since
bbc880ee amdk8/amdfam10: Use CAR_GLOBAL for sysinfo
This moved the copy of sysinfo in RAM from above the stack to below
the stack, but code for AP CPU's was not adjusted accordingly.

The code in src/cpu/x86/mtrr/mtrr.c disables caching in a few places when
changing mtrr settings. While I can't find anything that says that's actually
required, I can believe it's necessary. With that said, other code around the
wrmsr instructions which actually modify the settings should be able to run
with caching enabled with no ill effects.
This is particularly true for two calls to printk, one in the fixed mtrr code
and one in the variable, which could result in an arbitrary amount of work
being done without caching. When changing the implementation of the cbmem
console, these two printks caused a significant regression in boot performance
on link of about 70ms which is about 10% of total firmware boot time. When the
window where the cache is disabled is minimized, both this and the new
implementation were about 30ms faster than the original boot time.
For the variable MTRRs, we now store what we want to set the MSRs to and then
write them all at once at the end of commit_var_mtrrs(). This way we don't
have some set and some not, but we still minimize the time we spend with the
caches disabled.

This is essentially a revert of commit 10bd772d. The CAR_MIGRATE
mechanism is only useful to migrate variables from a special region
(e.g. cache as RAM) into DRAM-backed CBMEM between different parts of
the romstage (it does not persist into ramstage). Since ARM devices use
SRAM for which there is no reason to become inaccessible in later parts
of the romstage, this mechanism isn't useful for them. Removing it makes
the romstage.ld script much simpler, which has the nice side-effect of
putting the BSS at the end of the memory image (so that cbfstool can
actually figure out that it doesn't need to be part of the ROM image).

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.
The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

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.

ways to do this. Unfortunately changing this ends up touching nearly
every Exynos5 file, but I hope you agree that it's worth it (and the
sooner we get it over with, the better... I can't bring myself to make
another device fit into that ugly scheme).
This also removes the redundant EXYNOS5 base address definitions from
the 5420 directory when there are EXYNOS5420 ones, to avoid complete
confusion. The new scheme tries to use EXYNOS5 for base addresses and
exynos5 for types that are common between the two processors, and
EXYNOS5420/exynos5420 for things that have changes (although I probably
didn't catch all differences).

This cleans up a few minor things (mostly #defines) of the memory code
for exynos5420, pit, and kirby. Specifically:
- CONCONTROL.empty is read-only, so don't try to set it and also
get rid of the unneeded DMC_CONCONTROL_EMPTY_ENABLE #define.
- MEMBASECONFIG* overlaps members of the mem_timings struct and
are mainboard-dependent anyway, so get rid of 'em.
- DMC_MEMCONTROL_TP_DISABLE corresponds to a reserved bit. It may
have been deprecated.
- Same with TIMING* #defines.
- Clarify DDR_MODE_* usage and use mem->mem_type when appropriate.

This changes the number of chip selects that we configure from 2 to 1.
On current setups with (x16 memory 4Gbit chips) that means that we're
at 2GByte.
Technically we should add a second setting in the ares_ddr3_timings
and select between the two of the based on board strappings. That
would make the CONFIG_RUN_TIME_BANK_NUMBER work properly. I've
changed the ddr3_mem_ctrl_init() so it should handle that, but I'm not
actually doing the board strapping read right now.
This change means that accesses to 0xA0000000 - 0xFFFFFFFF on 2G
systems will no longer put the system in a messed up state (leading to
a hang). It also prevents some of the weird boot behavior that we've
seen that comes and goes depending on U-Boot alignment. See

This patch intends to remove all code which enables hardware read
leveling. We need to disable h/w read leveling because new ASV table
is merged in kernel (which is based on the new characterization
condition) and new characterization environment has h/w read leveling
disabled, so we should also disable this. Also, disabling h/w read
leveling improves the MIF LVcc value (LVcc value is the value at which
DDR will fail to work properly), improve LVcc means we have enough
voltage margin for MIF. When h/w leveling is enabled, we have almost
zero volatge margin.

As per hardware recommendation, CKE PAD retention release must
happen just before gate leveling enable and only in case of resume.
Hence, this patch moves pad retention release from dmc_common.c to
dmc_init_ddr3_exynos5420.c. In addition to this we are providing
125 (+3 extra being safe) times auto refresh to DRAM by sending
REFA direct command. This is required because when CKE PAD retention
release happens, self refresh mode of DDR3 is disabled.
Hence, auto refresh 125 times.
This is ported from https://gerrit.chromium.org/gerrit/#/c/65573
Note: Since WAKEUP_DIRECT does not go thru memory init, it should be
safe to move CKE PAD retention out of bootblock.c.

Also removes a superfluous invalidation line from the bootblock code...
dcache_mmu_enable/disable already take care of that.

snow and pit: turn on FET4 (for SD card) at bootup
Explictly enable FET4 on Snow and Pit.
Historically we haven't needed to do this because:
* On snow there's a bypass around FET4 which effectively eliminates
it. Even if we don't turn on FET4 the SD card is still powered.
Turning on FET4 doesn't hurt though and is technically correct.
* On pit the EC turns on FET4 on cold bootup.
On pit we run into a problem if the kernel turns off FET4 like in
<https://gerrit.chromium.org/gerrit/#/c/65332/> and then we get a
software reset or warm reset. In this case the EC won't know to turn
it back on.

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

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

access the banked registers of SVC mode from a different exception mode,
it changes Coreboot (and its payloads) to run in System mode instead. As
both modes can execute all privileged instructions, this should not have
any noticeable effect on firmware operation (please correct me if I'm
wrong!).

This improves firmware boot time substantially. Because cbmem isn't available
yet, we need to allocate some space in sram for the ttb. Doing cache
initialization in the bootblock means we can implement this once per CPU
instead of once per mainboard.

exynos5420: flush caches and disable MMU in resume path
This patch flushes the caches and disables the MMU before resuming.
c32b9b3 ("Set up caching in the bootblock.") had a bug where the
dcache and MMU remained enabled in the resume path. This caused
the machine to hang on resume. However, other bugs were preventing
us from testing this properly earlier on so it went unnoticed until
now.
