97a4b3edf0 binaryPI platforms: Drop any ACPI S3 support
No board with binaryPI currently supports HAVE_ACPI_RESUME. For
platforms with PSP the approach is also very different from what
we previously had here.

Furthermore, s3_resume.[ch] files under cpu/amd/pi do not
distinguish between NonVolatile and Volatile buffers of S3 storage.
This means the Volatile buffer that is maintained and available in
CBMEM is unnecessarily copied to SPI flash. This has been fixed on
open-source AGESA directory, so development of S3 suspend support
with binaryPI is better continued with that.

Unfortunately there are further complications and indications that
open-source AGESA may have always had a low-memory corruption
issue. This has to be investigated separately before restoring
or claiming S3 is supported on binaryPI.

03e6a455a3 amd/pi/hudson: Move APIC enable to CPU file
Relocate the enabling of the LAPIC out of the southbridge source and
surround it with a check for CONFIG_UDELAY_LAPIC (typical for AMD
systems).  The LAPIC is now enabled for all cores; not only the BSP,
and not only when the UART is used.

This solves the problem of APs not having their APICs enabled when
the timer is expected to be functional, e.g. verstage often uses
do_printk_va_list() instead of do_printk() which exits early for
APs when CONFIG_SQUELCH_EARLY_SMP=y.

The changes were tested with two Gardenia builds, one using verstage
and another with CONFIG_SQUELCH_EARLY_SMP=n.

75a3d1fb7c amdfam10: Perform major include ".c" cleanup
Previously, all romstages for this northbridge family
would compile via 1 single C file with everything
included into the romstage.c file (!)

This patch separates the build into separate .o modules
and links them accordingly.

Currently compiles and links all fam10 roms without
breaking other roms.

Both DDR2 and DDR3 have been completed

TESTED on REACTS: passes all boot tests for 2 boards
 ASUS KGPE-D16
 ASUS KFSN4-DRE

Some extra changes were required to make it compile
otherwise there were unused functions in included "c" files.
This is because I needed to exchange CIMX
for the native southbridge routines. See in particular:
 advansus/a785e-i
 asus/m5a88-v
 avalue/eax-785e

A followup patch may be required to fix the above boards.

c86c6b33e8 intel cache-as-ram: Move DCACHE_RAM_BASE
Having same memory region set as both WRPROT and WRBACK
using MTRRs is undefined behaviour. This could happen if
we allow DCACHE_RAM_BASE to be located within CBFS in SPI
flash memory and XIP romstage is at the same location.

As SPI master by default decodes all of top 16MiB below
4GiB, initial cache-as-ram line fills may have actually
read from SPI flash even in the case DCACHE_RAM_BASE was
below the nominal 4GiB - ROM_SIZE.

There are no reasons to have this as board-specific setting.

c28984d9ea spi: Clean up SPI flash driver interface
RW flag was added to spi_slave structure to get around a requirement on
some AMD flash controllers that need to group together all spi volatile
operations (write/erase). This rw flag is not a property or attribute of
the SPI slave or controller. Thus, instead of saving it in spi_slave
structure, clean up the SPI flash driver interface. This allows
chipsets/mainboards (that require volatile operations to be grouped) to
indicate beginning and end of such grouped operations.

New user APIs are added to allow users to perform probe, read, write,
erase, volatile group begin and end operations. Callbacks defined in
spi_flash structure are expected to be used only by the SPI flash
driver. Any chipset that requires grouping of volatile operations can
select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and
define callbacks for chipset_volatile_group_{begin,end}.

spi_claim_bus/spi_release_bus calls have been removed from the SPI flash
chip drivers which end up calling do_spi_flash_cmd since it already has
required calls for claiming and releasing SPI bus before performing a
read/write operation.

2bebd7bc93 cpu/x86/mtrr: allow temporary MTRR range during coreboot
Certain platforms have a poorly performing SPI prefetcher so even if
accessing MMIO BIOS once the fetch time can be impacted. Payload
loading is one example where it can be impacted. Therefore, add the
ability for a platform to reconfigure the currently running CPU's
variable MTRR settings for the duration of coreboot's execution.

The function mtrr_use_temp_range() is added which uses the previous
MTRR solution as a basis along with a new range and type to use.
A new solution is calculated with the updated settings and the
original solution is put back prior to exiting coreboot into the OS
or payload.

Using this patch on apollolake reduced depthcharge payload loading
by 75 ms.
