In order to make it easier to review, this change is being split into
multiple CLs. This is change 1/5 which moves .c files from arch/x86 to
acpi/.
The only acpi files that are still retained under arch/x86 are:
a. acpi_s3.c: This doesn't really deal with ACPI tables. Also, there
are some assumptions in there about SMM which will have to be resolved
if this file needs to be moved to common code.
b. acpi_bert_storage.c/bert_storage.h: This file is currently written
specifically with x86 in mind. So, not moving the file for now.
Motivation for this change: Not all stages on Picasso SoC are targeted
for the same architecture. For example, verstage (if runs before
bootblock) will be targeted for non-x86. This makes it difficult to
add device tree to verstage which would be required to get to SoC
configs from the tree. This is because the device tree on x86
platforms currently contains a lot of devices that require ACPI
related enums and structs (like acpi_gpio, acpi_pld, acpi_dp and so
on). Hence, this change removes all ACPI table support out of
arch/x86.

Hardware tests on the P2B-LS shows the generic hardware power button
is not working anyway - with FADT power button flag set, the board
could not power off with the button.
This change removes the generic hardware power button from all P2B
mainboards and relies completely on the fixed hardware power button.

AMD has rewritten AGESA (now at v9) for direct inclusion into UEFI
build environments. Therefore, unlike the previous Arch2008
(a.k.a. v5), it can't be built without additional source, e.g. by
combining with EDK II, and it has no entry points for easily
building it into a legacy BIOS.
AGESA in coreboot now relies on the FSP 2.0 framework published
by Intel and uses the existing fsp2_0 driver.
* Add fsp_memory_init() to romstage.c. Although Picasso comes out
of reset with DRAM alive, this call is added to maximize
compatibility and facilitate internal development. Future work
may look at removing it. AGESA reports the memory map to coreboot
via HOBs returned from fsp_memory_init().
* AGESA currently sets up MTRRs, as in most older generations.
Take ownership back immediately before running ramstage.
* Remove cbmem initialization, as the FSP driver handles this.
* Add chipset_handle_reset() for compatibility.
* Top of memory is determined by the FSP driver checking the HOBs
passed from AGESA. Note that relying on the TOM register happens
to be misleading when UMA is below 4GB.

The AMD64 Architecture Programmer's Manual, Volume 2: Systems
Programming says the following about variable MTRRs:
Variable Range Size and Alignment.
The size and alignment of variable memory-ranges (MTRRs) and I/O ranges
(IORRs) are restricted as follows:
* The boundary on which a variable range is aligned must be equal to the
range size. For example, a memory range of 16 Mbytes must be aligned on a
16-Mbyte boundary (i.e., naturally aligned).
* The range size must be a power of 2 (2^n , 52 > n > 11), with a minimum
allowable size of 4 Kbytes. For example, 4 Mbytes and 8 Mbytes are
allowable memory range sizes, but 6 Mbytes is not allowable.
Print out errors if these conditions are violated. I didn't assert since
`set_var_mtrr` can be used in boot block before the serial console is
enabled.
BUG=b:147042464
TEST=Boot trembyle and see MTRR errors:
MTRR Error: base 0xcc800000 must be aligned to size 0x1000000

Let's gather some documentation ideas for the season of docs. I reused
the project ideas style (thanks Patrick). Feel free to add yourself as a
mentor here. Also if you have more ideas, please add them to the
document.

Add GPIO_PCH_WP (GPP_C11) to associate GPP_PCH_WP with community
zero.
TEST=Build coreboot, flash, boot to
and log into kernel, execute "wp enable" in console,
execute "crossystem" at kernel prompt and verify that "wpsw_cur"
shows as being "1", Execute "wp disable" in console, execute
"crossystem" at kernel prompt and verify "wpsw_cur" is 0.
