Kyösti Mälkki b6a0fe59fc AGESA boards: Fix regressions with LATE_CBMEM_INIT
Some configurations of AGESA boards fail to boot after commit
  61be360 AGESA: Fix UMA calculations

Implementation of cbmem_find() for ENV_ROMSTAGE expects
that CBMEM has already been initialized. In the case of
LATE_CBMEM_INIT boards, this is not the case and cbmem_top()
returned NULL prior to the offending commmit.

By definition LATE_CBMEM_INIT does not have known cbmem_top()
in ENV_ROMSTAGE except for possible ACPI S3 resume path.

Marshall Dawson ce9c88348c arch/x86/assembly_entry: Align stack for car_stage_entry
At process _start, the stack is expected to be aligned to a
16-byte boundary.  Upon entry to any function the stack frame
must have the end of any arguments also aligned.  In other words
the value of %esp+4 or %rsp+8 is always a multiple of 16 (1).

Align the stack down and change the method for executing
car_stage_entry from jmp to call which should preserve proper
alignment regardless of a 32- or 64-bit build.

Although 4-byte alignment is the minimum requirement for i386,
some AMD platforms use SSE instructions which expect 16-byte.

   See "Initial Stack and Register State" and "The Stack Frame"
   in the supplements.

Julius Werner cd6b22f9a0 arch: Unify basic cache clearing API
Caching is a very architecture-specific thing, but most architectures
have a cache in general. Therefore it can be useful to have a generic
architecture-independent API to perform simple cache management tasks
from common code.

We have already standardized on the dcache_clean/invalidate naming
scheme that originally comes from ARM in libpayload, so let's just do
the same for coreboot. Unlike libpayload, there are other things than
just DMA coherency we may want to achieve with those functions, so
actually implement them for real even on architectures with
cache-snooping DMA like x86. (In the future, we may find applications
like this in libpayload as well and should probably rethink the API
there... maybe move the current functionality to a separate
dma_map/unmap API instead. But that's beyond scope of this patch.)

Julius Werner baa3e70084 arm64: Align cache maintenance code with libpayload and ARM32
coreboot and libpayload currently use completely different code to
perform a full cache flush on ARM64, with even different function names.
The libpayload code is closely inspired by the ARM32 version, so for the
sake of overall consistency let's sync coreboot to that. Also align a
few other cache management details to work the same way as the
corresponding ARM32 parts (such as only flushing but not invalidating
the data cache after loading a new stage, which may have a small
performance benefit).

until after AmdInitEnv().

Modify code such that weak backup functions are only defined

Aaron Durbin bc17cdef0d arch/x86: remove CAR global migration when postcar stage is used
When a platform is using postcar stage it's by definition not
tearing down cache-as-ram from within romstage prior to loading
ramstage. Because of this property there's no need to migrate
CAR_GLOBAL variables to cbmem.

Julius Werner e91d170d21 Remove libverstage as separate library and source file class
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.

There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.

This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).

Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

Julius Werner 58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

Julius Werner 94d9411415 vboot: Remove CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL Kconfig option
CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL allows the SoC directory to
provide its own main() symbol that can execute code before the generic
verstage code runs. We have now established in other places (e.g. T210
ramstage) a sort of convention that SoCs which need to run code in any
stage before main() should just override stage_entry() instead. This
patch aligns the verstage with that model and gets rid of the extra
Kconfig option. This also removes the need for aliasing between main()
and verstage(). Like other stages the main verstage code is now just in
main() and can be called from stage_entry().

Due to an unfortunate race between adding verstage support and reverting
an earlier hack that disabled the optimized assembly versions of
memcpy(), memmove() and memset() on ARM64, it seems that we never
enabled the optimized code for the verstage. This should be fixed so
that all stages use the same architecture support code.

AGESA vendorcode was always built with SSE enabled, but until

like GCC-6.3 more likely emits instructions that depend on the
16 byte alignment of stack.
