Add a utility to generate a compressed BIOS image for AMD Family 17h.
If the input is an elf file, the utility extracts the program portion
for compression. Otherwise the file is compressed as-is.
In modern AMD systems, the PSP brings up DRAM then uncompresses the
BIOS image into memory prior to x86 beginning execution. The PSP

This patch removes all possible dependencies in order to build platform
with CONFIG_RAMPAYLOAD enable(without ramstage).
A. Create coreboot separate stage kconfigs
This patch creates seperate stage configs as below
1. HAVE_BOOTBLOCK
2. HAVE_VERSTAGE
3. HAVE_ROMSTAGE
4. HAVE_POSTCAR
5. HAVE_RAMSTAGE
B. Also ensures below kconfigs are aligned with correct stage configs
1. COMPRESS_RAMSTAGE and RELOCATABLE_RAMSTAGE are now enable if
CONFIG_HAVE_RAMSTAGE is selected.
2. COMPRESS_BOOTBLOCK will enable if CONFIG_HAVE_BOOTBLOCK is set
3. COMPRESS_PRERAM_STAGES will enable if CONFIG_HAVE_VERSTAGE
|| CONFIG_HAVE_ROMSTAGE is selected.
C. Also fix compilation issue with !CONFIG_HAVE_RAMSTAGE
On x86 platform:
Case 1: ramstage do exist: CONFIG_HAVE_RAMSTAGE=1
>> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_x86_32
Case 2: ramstage doesn't exist: CONFIG_HAVE_RAMSTAGE=0
>> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_
This patch fixes Case 2 usecase where platform doesn't select
CONFIG_HAVE_RAMSTAGE.
Also add option to create sipi_vector.manual based on $(TARGET_STAGE)
variable.
$(TARGET_STAGE)=ramstage if user selects CONFIG_HAVE_RAMSTAGE
$(TARGET_STAGE)=postcar if user selects CONFIG_RAMPAYLOAD

The option to specify a binary file name was added later for platforms
that do not provide microcode updates in our blobs repository. Alas,
it wasn't visible what platforms these are. And if you specified a file

Make it visible which platforms don't provide binaries with the new con-
figs MICROCODE_BLOB_NOT_IN_BLOB_REPO, MICROCODE_BLOB_NOT_HOOKED_UP and
MICROCODE_BLOB_UNDISCLOSED. Based on that we can decide if we want to

ded (default to CPU_MICROCODE_CBFS_NONE).
Also split CPU_MICROCODE_CBFS_GENERATE into the more explicit
CPU_MICROCODE_CBFS_DEFAULT_BINS and CPU_MICROCODE_CBFS_EXTERNAL_BINS.
And clean up the visibility of options: Don't show CBFS related options
on platforms that don't support it and don't show external file options
if the platform uses special rules for multiple files (CPU_MICROCODE_
MULTIPLE_FILES).

N.B. When the `clang-format' binary is not found we issue a warning

It happens, I think, because the rule generated by

build/util/kconfig/conf, and something also builds it, at the same time.
Fix this case, by making this rule depend on $(objutil)/kconfig/conf.

Just not leaving the recipes empty seems to help here. I seeemed to

There were so many pitfalls that I wrote my own version of this even-
tually. This version is inspired by the procedure of Alex Thiessen[1].
Instead of generating a `build.h` on demand, we always generate a tem-
porary version that, if it differs from the current one, is added as
a dependency.
As we use .SECONDEXPANSION on the prerequisites, special care is taken
that we won't generate the file twice. As it would be too late to add
the dependency if we'd run `genbuild_h.sh` inside a recipe, we have
to run it through the `$(shell)` function. But that brings us to the
next issue: The make variables used by `genbuild_h.sh` are not expor-
ted to this shell like they would be in a recipe. So we export them
manually. We could also make these variables explicit parameters of
`genbuild_h.sh` instead.
An alternative to always creating the temporary `build.h` would be
to add a phony target as dependency instead, and finally calling
`genbuild_h.sh` again in case we need an update. But, um, we create
so many files anyway...

This change adds a new config option OVERRIDE_DEVICETREE that allows
variants to provide an override devicetree file to override the
registers and/or add new devices on top of the ones provided by
baseboard devicetree using CONFIG_DEVICETREE.

Masked ROMs are the silent killers of boot speed on devices without
memory-mapped SPI flash. They often contain awfully slow SPI drivers
(presumably bit-banged) that take hundreds of milliseconds to load our
bootblock, and every extra kilobyte of bootblock size has a hugely
disproportionate impact on boot speed. The coreboot timestamps can never
show that component, but it impacts our users all the same.
This patch tries to alleviate that issue a bit by allowing us to
compress the bootblock with LZ4, which can cut its size down to nearly
half. Of course, masked ROMs usually don't come with decompression
algorithms built in, so we need to introduce a little decompression stub
that can decompress the rest of the bootblock. This is done by creating
a new "decompressor" stage which runs before the bootblock, but includes
the compressed bootblock code in its data section. It needs to be as
small as possible to get a real benefit from this approach, which means
no device drivers, no console output, no exception handling, etc.
Besides the decompression algorithm itself we only include the timer
driver so that we can measure the boot speed impact of decompression. On
ARM and ARM64 systems, we also need to give SoC code a chance to
initialize the MMU, since running decompression without MMU is
prohibitively slow on these architectures.
This feature is implemented for ARM and ARM64 architectures for now,
although most of it is architecture-independent and it should be
relatively simple to port to other platforms where a masked ROM loads
the bootblock into SRAM. It is also supposed to be a clean starting
point from which later optimizations can hopefully cut down the
decompression stub size (currently ~4K on RK3399) a bit more.
NOTE: Bootblock compression is not for everyone. Possible side effects
include trying to run LZ4 on CPUs that come out of reset extremely
underclocked or enabling this too early in SoC bring-up and getting
frustrated trying to find issues in an undebuggable environment. Ask
your SoC vendor if bootblock compression is right for you.

This patch adds the CCACHE_EXTRAFILES variable to the list of exported
environment variables, which can be useful as a target-specific variable
to make ccache aware of extra dependencies that it cannot figure out on
its own. It also adds a CPPFLAGS parameter to define the __BUILD_DIR__
constant for the preprocessor so that the current output build directory
can be referenced in C code if necessary.

This patch moves the objcopy invocation that changes the bootblock's
section flags to make sure .data and .bss are preserved in the binary
image from the generation of bootblock.raw.bin into a separate
bootblock.raw.elf file. Some SoCs (like SDM845) like to have an ELF
rather than a raw binary as input to their masked ROM wrapper
generation script.
Also move those objcopy flags out into a variable because I'll need them
again in a later patch.

As I mention in the comment, this is valid ASL, which was added as
a warning with the comment "This would appear to be worthless in
real-world ASL code." While code using empty resource templates
could probably be rewritten, this seems like an arbitrary choice
to generate this as a warning, since it's valid.
This gets rid of warnings such as this one:
dsdt.aml 2975: Return (ResourceTemplate() {})
Warning 3150 - Empty Resource Template (END_TAG only)
Which is generated by this code in google/rambi/acpi/mainboard.asl:

{
/* Only return interrupt if I2C1 is PCI mode */
If (LEqual (\S1EN, 0)) {
Return (^RBUF)

/* Return empty resource template otherwise */
