Flash prefers 32-bit sequential access. On some platforms ROM is
not cached due to i.a. MTRR shortage. Moreover ROM caching is not

The punit is responsible for a number of things. Without
performing the sequence included it won't change processor
frequency when requested and apparently there are some bizarre
hangs introduced if this sequence isn't included either. Lastly,
this needs to come after microcode has been loaded. As that is
done in bootblock the ordering is correct.
One other side effect is that this fixes the graphics devices'
device id. Before it was showing up as the same device id of the
SoC transaction router.

Original intention was to set the frequency for 'Fast Read' command

Modified register contains SPI frequency for 'Normal Read' command
in bits 13..12. Default for this is 11b for 16.5 MHz. Existing code
unintentionally clears these bits, increasing SPI frequency to 66MHz
for 'Normal Read' command.
This is above specifications for many common SPI flash components
and also makes flashrom older than 0.9.7-r1750 to operate unreliably

This completes the improvements to the ELF file parsing code. We can
now parse section headers too, across all 4 combinations of word size
and endianness. I had hoped to completely remove the use of htonl
until I found it in cbfs_image.c. That's a battle for another day.
There's now a handy macro to create magic numbers in host byte order.
I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe
we can use it for the others too, but this is sensitive code and
I'd rather change one thing at a time.
To maximize the ease of use for users, elf parsing is accomplished with
just one function:
int
elf_headers(const struct buffer *pinput,
Elf64_Ehdr *ehdr,
Elf64_Phdr **pphdr,
Elf64_Shdr **pshdr)
which requires the ehdr and pphdr pointers to be non-NULL, but allows
the pshdr to be NULL. If pshdr is NULL, the code will not try to read
in section headers.
To satisfy our powerful scripts, I had to remove the ^M from an unrelated
microcode file.

The AGESA resumes the GPP ports in the romstage using FchInitResetGpp(),
which does FchGppPortInitS3Phase() for S3 resume. The PreInitGppLink()
looks into CMOS to figure out what ports to just force to Gen1 or
Gen2 PCIe. Then boot continues and in the ramstage the rest of GPP
init is executed. There is a problem that nobody sets properly the
PortDetected flags in the S3 path. As the consequence FchGppDynamicPowerSaving()
thinks the GPP port is not enabled and shut downs it.
The best fix would be also to remove the CMOS dependency which
might be some left over, because AGESA does not use CMOS much for
anything else. There could be also some way how to pass the GPP state
structure from romstage to ramstage possibly via hudson/resume.c
but I don't know how to do that. Similar problem is that the "late"
stage of init again "forgets" the PortDetected state.
This fix fixes the resume issue on Asus F2A85-M. With this patch applied
both GPP ports (used as PCIe x1 and internal ethernet) are working again
after resume.

The initial Bay Trail code is intended to support
the mobile and desktop version of Bay Trail. This support
can train memory and execute through ramstage. However,
the resource allocation is not curently handled correctly.
The MRC cache parameters are successfully saved and reused
after the initial cold boot.

In the past the turbo disable setting (bit 38) of the
IA32_MISC_ENABLES msr has been package scoped. That means
knocking the turbo disable bit down enabled turbo for the
entire package. Sadly, that's no longer true on all Intel
processors. Therefore, allow non-packaged scoped turbo
setting by introducing the CPU_INTEL_TURBO_NOT_PACKAGE_SCOPED
Kconfig option. It defaults to false which was the original
assumption.

In order for the cpu code to start SMM relocation 2 new
functions are added to be shared:
- void smm_initiate_relocation_parallel()
- void smm_initiate_relocation()
The both initiate an SMI on the currently running cpu.
The 2 variants allow for parallel relocation or serialized
relocation.

Provide a common entry point for bringing up the APs
in parallel. This work is based off of the Haswell one
which can be moved over to this in the future. The APs
are brought up and have the BSP's MTRRs duplicated in
their own MTRRs. Additionally, Microcode is loaded before
enabling caching. However, the current microcode loading
support assumes Intel's mechanism.
The infrastructure provides a notion of a flight plan
for the BSP and APs. This allows for flexibility in the
order of operations for a given architecture/chip without
providing any specific policy. Therefore, the chipset
caller can provide the order that is required.

Haswell was the original chipset to store the cache
in another area besides CBMEM. However, it was specific
to the implementation. Instead, provide a generic way
