31d49ec117 soc/amd/common/block/gpio_banks: Use configure_scimap()
There is no need to stash the SCI trigger register configuration and
apply it at the end. Remove this to make SCI and SMI programming more
symmetrical and to use available configure_scimap function instead of
implementing it again, but without the additional checks. Using this
function also allows removing soc_route_sci.

43cd1c0bbe soc/amd/common/block/pm: rework pm_set_power_failure_state
Picasso and Stoneyridge didn't do a read-modify-write operation on the
lower nibble of PM_RTC_SHADOW_REG, but just wrote the upper nibble as
all zeros. Since the upper nibble might be uninitialized before the
lower nibble gets written, do what Picasso and Stoneyridge did here
instead of what the reference code does. Also add a comment why and how
this register behaves a bit weird.

151cc6c14b soc/amd/common/block/pm: remove POWER_STATE_DEFAULT_ON_AFTER_FAILURE
Not selecting POWER_STATE_DEFAULT_ON_AFTER_FAILURE brings Cezanne that
is currently the only SoC using this functionality in line with Picasso
where the default is that the board remains in power off mode after
power was lost and later restored. Boards can change this behavior by
selecting POWER_STATE_OFF_AFTER_FAILURE, POWER_STATE_ON_AFTER_FAILURE or
POWER_STATE_PREVIOUS_AFTER_FAILURE.

a643e212c2 soc/amd/common/block/gpio: remove SoC type check in gpio_fill_wake_state
Verified that all accessed registers exist in all SoCs that use this
code (Carrizo, Mullins, Stoneyridge, Picasso and Cezanne at the moment)
and that the bit definitions match as well. Also at the time of writing
this patch only Picasso calls gpio_fill_wake_state, so dropping the
check won't change behavior. This also avoids having SoC specific code
that doesn't get selected by Kconfig options in the common AMD SoC
directory and also avoids having to add a check for SOC_AMD_CEZANNE to
support this functionality on Cezanne in a follow-up patch.

b95f848766 soc/amd: Make espi_clear_decodes private

change consolidates the clear logic into one spot.

This shouldn't result in a behavior change on Picasso. Picasso already
has the eSPI decodes clear on boot, so this change is a nop.

This sets the eSPI registers to the reset values specified in the PPR.

On Cezanne, the PSP modifies these registers such that the eSPI

These reset values are identical to what is currently used on Zork.

opens if-statement package, acpigen_write_if_end() closes it.
Now acpigen_write_else() closes previously opened acpigen_write_if(),
so acpigen_pop_len() is not required before it.

4f87ae1d4a soc/amd/common/block/i2c: Move SoC agnostic parts into common
The logic behind I2C bus initialization, I2C MMIO base address getter
and setter, I2C bus ACPI name resolution are identical for all the AMD
SoCs. Hence moving all the SoC agnotic parts of the driver into the
common driver and just configure the SoC specific parts into individual
I2C drivers.

0dbea48d46 soc/amd/common: Introduce I2C driver common to all AMD SoCs
I2C driver is replicated in each generation of AMD SoCs. Introduce a
common I2C driver that can be used across all the AMD SoCs. To begin
with, peripheral reset functionality is moved into this common driver.
SoC specific I2C driver passes the SCL pin configuration in order for
the common driver to reset the peripherals. More functionality can be
moved here in subsequent changes.

Also sb_reset_i2c_slaves() is renamed as sb_reset_i2c_peripherals() as
an effort towards using inclusive language.

77639e4537 cbfs: Replace more instances of cbfs_boot_locate() with newer APIs
In pursuit of the eventual goal of removing cbfs_boot_locate() (and
direct rdev access) from CBFS APIs, this patch replaces all remaining
"simple" uses of the function call that can easily be replaced by the
newer APIs (like cbfs_load() or cbfs_map()). Some cases of
cbfs_boot_locate() remain that will be more complicated to solve.

81dc20e744 cbfs: Move stage header into a CBFS attribute
The CBFS stage header is part of the file data (not the header) from
CBFS's point of view, which is problematic for verification: in pre-RAM
environments, there's usually not enough scratch space in CBFS_CACHE to
load the full stage into memory, so it must be directly loaded into its
final destination. However, that destination is decided from reading the
stage header. There's no way we can verify the stage header without
loading the whole file and we can't load the file without trusting the
information in the stage header.

To solve this problem, this patch changes the CBFS stage format to move
the stage header out of the file contents and into a separate CBFS
attribute. Attributes are part of the metadata, so they have already
been verified before the file is loaded.

Since CBFS stages are generally only meant to be used by coreboot itself
and the coreboot build system builds cbfstool and all stages together in
one go, maintaining backwards-compatibility should not be necessary. An
older version of coreboot will build the old version of cbfstool and a
newer version of coreboot will build the new version of cbfstool before
using it to add stages to the final image, thus cbfstool and coreboot's
stage loader should stay in sync. This only causes problems when someone
stashes away a copy of cbfstool somewhere and later uses it to try to
extract stages from a coreboot image built from a different revision...
a debugging use-case that is hopefully rare enough that affected users
can manually deal with finding a matching version of cbfstool.

The SELF (payload) format, on the other hand, is designed to be used for
binaries outside of coreboot that may use independent build systems and
are more likely to be added with a potentially stale copy of cbfstool,
so it would be more problematic to make a similar change for SELFs. It
is not necessary for verification either, since they're usually only
used in post-RAM environments and selfload() already maps SELFs to
CBFS_CACHE before loading them to their final destination anyway (so
they can be hashed at that time).

2e973942bc program_loading: Replace prog_rdev() with raw start pointer and size
Since prog_locate() was eliminated, prog_rdev() only ever represents the
loaded program in memory now. Using the rdev API for this is unnecessary
if we know that the "device" is always just memory. This patch changes
it to be represented by a simple pointer and size. Since some code still
really wants this to be an rdev, introduce a prog_chain_rdev() helper to
translate back to that if necessary.

1de8708fe5 cbfs: Remove prog_locate() for stages and rmodules
This patch removes the prog_locate() step for stages and rmodules.
Instead, the stage and rmodule loading functions will now perform the
locate step directly together with the actual loading. The long-term
goal of this is to eliminate prog_locate() (and the rdev member in
struct prog that it fills) completely in order to make CBFS verification
code safer and its security guarantees easier to follow. prog_locate()
is the main remaining use case where a raw rdev of CBFS file data
"leaks" out of cbfs.c into other code, and that other code needs to
manually make sure that the contents of the rdev get verified during
loading. By eliminating this step and moving all code that directly
deals with file data into cbfs.c, we can concentrate the code that needs
to worry about file data hashing (and needs access to cbfs_private.h
APIs) into one file, making it easier to keep track of and reason about.

This patch is the first step of this move, later patches will do the
same for SELFs and other program types.
