Currently ifdtool --validate will not correctly validate the FMAP
against the IFD regions, since it will compare the IFD bios region with
an FMAP region called SI_BIOS.
It's probably a good idea to define default name for the BIOS FMAP
region like we have for 'COREBOOT' or 'FMAP' FMAP region.

On systems that do not provide their own *.fmd (Flashmap) file, we
fall back to a default flashmap file. That file however does not contain
the blobs (ME, GBE ...), that are usually placed below the BIOS Flashmap.
It can therefore easily happen that the placement of the blobs collides
with the placement of the BIOS region (e.g. if CBFS_SIZE is big enough).
The fmaptool can't catch that, since it does not know of the blobs
placement.
This patch basically maps the regions described in the IFD (Intel
Firmware Descriptor) to the default Flashmap.
Test: Build and see that build/fmap.fmd contains all blobs now (on intel
systems that are supported by the ifdtool)

Use the pstate_msr union in get_pstate_info to check if the P state
enable bit is set. Also drop the now unused PSTATE_DEF_HI_ENABLE_SHIFT
and PSTATE_DEF_HI_ENABLE_MASK definitions.

Add the pstate_msr union of a bitfield struct and a raw uint64_t to
allow easier access of the bitfields of the P state MSRs which will be
implemented in a following patch. PPR #57254 Rev 1.52 was used as a
reference. This patch adds and uses the cpu_vid_8 bit which is the 9th
bit of the voltage ID specified in the SVI3 spec. The way the CPU
frequency is encoded in the PSTATE MSR has changed compared to Phoenix,
so also update the comment in the SoC's Kconfig file that the selected
SOC_AMD_COMMON_BLOCK_TSC_FAM17H_19H is likely incompatible which will be
addressed in the future.

Intel Client PCIe* controller expects each device should drive the
SRCCLKREQ#. If the GPIO is set to native mode for a device, which does
not support SRCCLKREQ#, then during RTD3 exit link would not be
established. Because controller samples the SRCCLKREQ# before
detecting the device and break L1 as the system might enter L1SS as
controller detects SRCCLKREQ# as de-asserted.
As a workaround the Pins must not be configured in Native Mode (CLKREQ
native function). Therefore here they are not configured at all.
source: 689882 (intel document ID)
So apparently hardware doesn't sample SRCCLKREQ Pin if it's not
configured as such.
That workaround suggestion however also brought a patch to FSP, which
in turn causes the same bug (even if SRCLKREQ are not configured).
Usually in order to make use of root port power saving features (e.g.
clock gating), the Root port must either be disabled or a CLKREQ Pin
must be configured. The patch however removed that check before
enabling power management for the rootport.
Workaround (until FSP is fixed):
pretend to FSP that the rootports have a CLKREQ Pin attached, by
supplying them in the FSP UPDs. That will cause FSP to configure the
CLKREQ Pin and enable power management for said rootport, but it will
not crash on L1 entry/exit. That has been done on the Atlas board
(as workaround) for a short period of time (before applying FSP Fix)
like this:
// RP 5 (the rootport you want to fix)
- memupd->FspmConfig.PcieClkSrcUsage[2] = 4;
// e.g. choose a clkreq pin that is not routed out
- memupd->FspmConfig.PcieClkSrcClkReq[2] = 0;
Furthermore disable CpuPcieRpClockReqMsgEnable FSP-M options to prevent
the same issue, but for CPU root ports. If not done the following will
happen in coreboot:

This patch is only a workaround for the issue and it will be reverted as
soon as FSP is fixed.
