The imd (internal memory database) library provides a way to
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.

for the new varible, which will always be 0 for the old RO and can

This patch fixes a bug that caused non-x86 boards to use the poor man's
assert() version with a lot more instructions per invocation and
hexadecimal line numbers in __PRE_RAM__ environments. This was really
just an oversight in the ARM port... even x86 uses a proper printk() in
most cases (those with CAR) and there's no reason not to do so on the
generally even more flexible SRAM-based architectures.
Additionally, it adds a new Kconfig option to make failed assertions and
BUG() calls halt again. This seems to have been the original intention,
but was commented out once out of fear that this might prevent
production systems from booting. It is still a useful debugging feature
though (since otherwise assertions can easily just scroll past and get
overlooked), so the user should be able to decide the this based on his
needs.
(Also changed error messages for both to include the word "ERROR", since
grepping for that is the most sophisticated way we currently have to
detect firmware problems. Some automated Chromium OS suspend tests check
for that.)

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.

We've traditionally tucked the framebuffer at the end of memory (above
CBMEM) on ARM and declared it reserved through coreboot's resource
allocator. This causes depthcharge to mark this area as reserved in the
kernel's device tree, which may be necessary to avoid display corruption
on handoff but also wastes space that the OS could use instead.
Since rk3288 boards now have proper display shutdown code in
depthcharge, keeping the framebuffer memory reserved across the handoff
(and thus throughout the lifetime of the system) should no longer be
necessary. For now let's just switch the rk3288 implementation to define
it through memlayout instead, which is not communicated through the
coreboot tables and will get treated as normal memory by depthcharge.
Note that this causes it to get wiped in developer/recovery mode, which
should not be a problem because that is done in response to VbInit()
(long before any images are drawn) and 0 is the default value for a
corebootfb anyway (a black pixel).
Eventually, we might want to think about adding more memory types to
coreboot's resource system (e.g. "reserved until kernel handoff", or
something specifically for the frame buffer) to model this situation
better, and maybe merge it with memlayout somehow.

A payload may want to run erase operations on SPI NOR flash without
re-probing the device to get its properties. This patch passes up
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.

Coreboot is designed to have a single serial console at most, on top
of that it may have a CBMEM (virtual) console. Matters are complicated
by the fact that console interface is different between bootblock and
later stages.
A linker list of console driver descriptors is used to allow to
determine the set and type of console drivers at compile time. Even
though the upstream seems to have done away with this approach, which
does not seem the best idea.
As an alternative this patch introduces a common wrapper which
different UART drivers can plug in into. The driver exports a single
API which can be used both directly (in bootblock) and through the
wrapper (in later stages).
The existing drivers can be adjusted to fit this scheme one by one.
The common UART driver API also aligns fine with the upstream
approach.

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).

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.)

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.

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.

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.

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

This patch adds the macros __ROMSTAGE__ and __RAMSTAGE__ which get
predefined in their respective stages by make, so that we have one
specific macro for every stage. It also renames __BOOT_BLOCK__ and
__VER_STAGE__ to __BOOTBLOCK__ and __VERSTAGE__ for consistency.
This change is intended to provide finer control and clearer
communication of intent after we added a new (optional) stage that falls
under __PRE_RAM__, and will hopefully provide some robustness for the
future (we don't want to end up always checking for romstage with #if
defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) &&
!defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The
__PRE_RAM__ macro stays as it is since many features do in fact need to
differentiate on whether RAM is available. (Some also depend on whether
RAM is available at the end of a stage, in which case #if
!defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be
authoritative.)
It's unfeasable to change all existing occurences of __PRE_RAM__ that
would be better described with __ROMSTAGE__, so this patch only
demonstratively changes a few obvious ones in core code.
BUG=None
TEST=None (tested together with dependent patch).

Extend lib/reg_script.c to use a platform table to declare
additional platform specific register access routine functions.
REG_SCRIPT_TYPE_PLATFORM_BASE is the starting value for platform
specific register types. Additional register access types may be
defined above this value. The type and access routines are placed
into reg_script_type_table.
The Baytrail type value for IOSF was left the enumeration since it
was already defined and is being used for Braswell.
BRANCH=none
BUG=None
TEST=Use the following steps to test:
1. Build for a Baytrail platform
2. Build for the Samus platform
3. Add a platform_bus_table routine to a platform which returns the
address of an array of reg_script_bus_entry structures and the
number of entries in the array.

Instead of having different structures for loading
ramstage and payload align to using struct prog.
This also removes arch_payload_run() in favor of
the prog_run() interface.

The prog_run() function abstracts away what is required
for running a given program. Within it, there are 2
calls: 1. platform_prog_run() and 2. arch_prog_run().
The platform_prog_run() allows for a chipset to intercept
a program that will be run. This allows for CPU switching
as currently needed in t124 and t132.

The struct prog serves as way to consolidate program
loading. This abstraction can be used to perform more
complicated execution paths such as running a program
on a separate CPU after it has been loaded. Currently
t124 and t132 need to do that in the boot path. Follow
on patches will allow the platform to decide how to
execute a particular program.
Note: the vboot path is largely untouched because it's
already broken in the coreboot.org tree. After getting
all the necessary patches pushed then vboot will be
fixed.
