Calling disable_cache_as_ram() with valuables in stack is not
a stable solution, as per documentation AMD_DISABLE_STACK
should destroy stack in cache.
While we still preserve cache contents (there is wbinvd deep
inside AMD_DISABLE_STACK macro), we now actually do a stack
switch and much more closely meet the specification of CAR
teardown sequence in AGESA specifications.
We now somewhat incorrectly include files from agesa/ tree,
but the whole agesawrapper.c file removal will address the
issue of overall directory layout.

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.

1. Explicitly add LOGICAL to the reset macro name to make it explicit
that the values are logical.
2. Reword some of the comments and combine them into single comment
instead of scattering the comments throughout.
3. Use c99 struct initializers for the reset mapping array.
4. For the chipset specific values use literals that match the hardware.
5. Use 'U' suffixes on the literals so we don't trip up compiler being
over zealous on undefined behavior.
6. Use unsigned and fixed-width types for the reset mapping structure
since the code is reliant on matching up with a register definition.
7. Fix formatting that can fit < 80 cols.

Big core uses a single device while small cores use one ACPI device

to retain the correct behavior.

The function find_fsp() parses the FSP header and returns either a valid
pointer to the FSP_INFO_HEADER or an error code. The caller of
find_fsp() only takes care about a NULL-pointer but not about a possible
error code. This leads to memory access violations in case of error when
FspTempRamInit is called.
To avoid this and to let the user know that there was an error while
parsing the FSP header show an error message and the error code.

This patch adds a new kind of compile-time assertion based on Linux'
compiletime_assert(). The difference to the existing use of
_Static_assert() in coreboot (which should continue to be used where
appropriate) is that this new assertion only hits if the call to it is
not optimized out at compile time. It is therefore ideal to assert that
certain code paths are not included in the image if a certain Kconfig
option is (not) set. For example,
assert(!IS_ENABLED(CONFIG_THAT_MAKES_THIS_INAPPROPRIATE));
can be rewritten as
if (!IS_ENABLED(CONFIG_THAT_MAKES_THIS_INAPPROPRIATE))
dead_code("This code shouldn't be built for config X");
to turn it into a compile-time check.

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.
