In AGESA specification AmdInitEnv() is to be called once
host memory allocator has started. In coreboot context this
could mean either availability of CBMEM or malloc heap.
As for AmdS3LateRestore(), there is no requirement to have
it run as part of the romstage either.

We define AGESA_LEGACY_WRAPPER a method of calling AGESA
via functions in agesawrapper.c file. The approach implemented
there makes it very inconvenient to do board-specific
customisation or present common platform-specific features.
Seems like it also causes assertion errors on AGESA side.
The flag is applied here to all boards and then individually
removed one at a time, as things get tested.
New method is not to call AGESA internal functions directly,
but via the dispatcher. AGESA call parameters are routed to
hooks in both platform and board -directories, to allow for
easy capture or modification as needed.
For each AGESA dispatcher call made, eventlog entries are
replayed to the console log. Also relocations of AGESA heap
that took place are recorded.
New method is expected to be compatible with binaryPI.

This was guarded because AGESA.h only defined it starting from fam15
header files. We can simply test if it has been defined.
The way coreboot currently handles this request, is to make the
allocation outside the heap, since heap may not be in CBMEM and thus
not available runtime. The acquired buffer from Allocate() would not
be found with Locate() or Deallocate(), so move the alloc_cbmem()
call for better code symmetry.

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.

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.

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.

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.

Therefore, the error appears to be triggered by an upstream C1E request.
This was eventually traced to concurrent access to the SP5100's SPI Flash controller by
multiple APs during startup. Calls to the nvram read functions get_option and read_option
call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash

The existing code did not properly detect various link attributes
on Family 10h/15h processors. With the addition of new HT3- and
IOMMU-specific code, proper detection has become critical to avoid
system deadlocks.

All modern Opteron processors support the HT probe filter,
which helps to increase coherent fabric performance by
reducing the number of HT transactions per cache probe.
AMD recommends that the probe filter be enabled on all
systems with more than two nodes, and it does not hurt
to enable it on systems with 2 nodes.

This patch adds CC6 power save support to the AMD Family 15h
support code. As CC6 is a complex power saving state that
relies heavily on CPU, northbridge, and southbridge cooperation,
this patch alters significant amounts of code throughout the
tree simultaneously.
Allowing the CPU to enter CC6 allows the second level of turbo
boost to be reached, and also provides significant power savings
when the system is idle due to the complete core shutdown.
