Hash table containing hashes of all signed PSP binaries is compiled at
build time and installed into the concerned CBFS. During boot, PSP
verstage reads the hash table binary and passes it to PSP bootloader.
PSP bootloader in turn uses the hash table to verify the signed PSP
binaries. Currently the hashes for all the signed PSP binaries are
compiled into one hash table. On upcoming platforms with more number of
signed PSP binaries, PSP bootloader does not have resources to handle
one monolithic hash table. Instead PSP bootloader recommends splitting
them into smaller hash tables (currently limited to 3 hash tables).
Update amdfwtool tool to support splitting hash tables. This is done by
adding an optional hash table id to the entries in the amdfw.cfg file.
By default, one hash table binary is always compiled and it's name is of
the format ${signed_rom}.hash. If an entry has a hash table id defined,
then this utility will compile a separate hash table binary whose name
is of the format ${signed_rom}.${N}.hash where N is the hash table id.

Enable early caching of the TOM region to optimize the boot time by
selecting `SOC_INTEL_COMMON_BASECODE_RAMTOP` config.
Purpose of this feature is to cache the TOM (with a fixed size of
16MB) for all consecutive boots even before calling into the FSP.
Otherwise, this range remains un-cached until postcar boot stage
updates the MTRR programming. FSP-M and late romstage uses this
uncached TOM range for various purposes (like relocating services
between SPI mapped cached memory to DRAM based uncache memory) hence
having the ability to cache this range beforehand would help to
optimize the boot time (more than 50ms as applicable).

When the default pci_domain_read_resources() is used,
keep 32-bit memory resources below the limit given by
CONFIG_DOMAIN_RESOURCE_32BIT_LIMIT. This serves as a
workaround for missing/wrong reservations of chipset
resources.
This will help to get more stable results from our own
allocator, but is far from a complete solution. Indvi-
dual platform ASL code also needs to be considered, so
the OS won't assign conflicting resources.
Most platforms have reserved space between 0xfe000000
and the 4G barrier. So use that as a global default.
In case of `soc/intel/common/`, use 0xe0000000 because
this is what is advertised in ACPI and there are traces
of resources below 0xfe000000 that are unknown to core-
boot's C code (PCH_PRESERVED_BASE?).

Don't assume only one IO and one MEM domain resource.
Currently the code is awkward for bridge devices where loops over
resources are done twice. This would be avoided on top of other patches
that improve the allocator (topic:allocator) by adding a top-down mode.
However those patches break the tree and having the option to have
multiple resources per type would make it easier to get those patches in
without breaking the tree.

This patch refers and backport some of previous work from Linux Kernel
(https://lore.kernel.org/all/1561689337-19390-3-git-send-email-ricardo.
neri-calderon@linux.intel.com/T/#u) that optimizes the MTRR register
programming in multi-processor systems by relying on the CPUID
(self-snoop feature supported).
Refer to the details below:
Programming MTRR registers in multi-processor systems is a rather
lengthy process as it involves flushing caches. As a result, the
process may take a considerable amount of time. Furthermore, all
processors must program these registers serially.
`wbinvd` instruction is used to invalidate the cache line to ensure
that all modified data is written back to memory. All logical processors
are stopped from executing until after the write-back and invalidate
operation is completed.
The amount of time or cycles for WBINVD to complete will vary due to the
size of different cache hierarchies and other factors. As a consequence,
the use of the WBINVD instruction can have an impact on response time.
As per measurements, around 98% of the time needed by the procedure to
program MTRRs in multi-processor systems is spent flushing caches with
wbinvd(). As per the Section 11.11.8 of the Intel 64 and IA 32
Architectures Software Developer's Manual, it is not necessary to flush
caches if the CPU supports cache self-snooping (ss).
"Flush all caches using the WBINVD instructions. Note on a processor
that supports self-snooping, CPUID feature flag bit 27, this step is
unnecessary."
Thus, skipping the cache flushes can reduce by several tens of
milliseconds the time needed to complete the programming of the MTRR
registers:

This patch removes the wbinvd call preceding CR0.CD setting in
disable_cache() to improve the boot time performances. According to
some experimental measurements, the wbinvd execution takes between 1.6
up and 6 milliseconds to complete so it is preferable to call it only
when necessary.
According to Intel Software Developer Manual Vol 3.A - 12.5.3
Preventing Caching section there is no need to flush and invalidate
the cache before settings CR0.CD. The documented sequence consists in
setting CR0.CD and then call wbinvd.
We also could not find any extra requirements in the AMD64
Architecture Programmer’s Manual - Volume 2 - Memory System chapter.
This extra wbinvd in coreboot disable_cache() function does not seem
documented and looking into the history of the project got us all the
way back to original commit 8ca8d7665d ("- Initial checkin of the
freebios2 tree") from April 2003.
Even the original disable_cache() implementation (see below) is a bit
curious as the comment list two actions:
1. Disable cache cover by line 74, 75 and 77
2. Write back the cache and flush TLB - Line 78
But it does not provide any explanation for the wbinvd call line 76.
68 static inline void disable_cache(void)
69 {
70 unsigned int tmp;
71 /* Disable cache */
72 /* Write back the cache and flush TLB */
