The FSP-M binary needs to fit into the memory region that starts at
FSP_M_ADDR and is FSP_M_SIZE bytes large, so error out during build time
if the uncompressed FSP-M file is larger than the size of the region it
will be copied into.

PSP_Verstage will take almost the entire time to run that
is allotted to S0i3 resume. Since coreboot isn't running,
the PSP needs to handle any security requirements. The long-
term plan is that the PSP won't even load psp_verstage on S0i3
resume, but when it is loaded, this makes sure we exit
immediately

There are gremlins in the system. thread_coop_enable has an assert. This
is currently problematic for two reasons.
assert(current->can_yield <= 0);
When doing smm_do_relocate we are entering a deadlock. The root cause
hasn't been quite found yet, but it's related to co-op multi-threading.
For some reason the assert in thread_coop_enable is firing when
releasing the console_lock spin lock. I'm assuming cpu_info hasn't been
initialized yet. The assert tries to perform a printk, but since the
console_lock is still held we end up in a dead lock. This dead lock will
generally not happen after a warm reset. Again I'm assuming because the
cpu_info struct has some valid values at this point.
For now disable multi-tasking until we fix the cpu_info initialization.

Add a new Kconfig option to enable or disable the 4 DWORD burst support
of the SPI controller and use this setting to determine if the
corresponding feature bit in SPI100_HOST_PREF_CONFIG will be set or
cleared. Since fch_spi_disable_4dw_burst can now enable or disable the
feature, rename it to fch_spi_configure_4dw_burst. On Stoneyridge the
SPI_RD4DW_EN_HOST bit needs to be cleared (see the Rd4dw_en_host bit
definition in the SPIx2C SPI100 Host Prefetch Config register in the
public BKDG #55072 Rev 3.09), so add a SoC dependency to the Kconfig
option.

A valid GEVENT number is never negative. The local variable in
set_single_gpio still needs to be a signed integer, since the return
value of get_gpio_gevent being -1 indicates that the GPIO can't generate
a GEVENT. The check for that makes the function return before calling
program_smi of program_sci, so the parameter of those functions can be
changed to unsigned.

The biosram accessor support in soc/amd/common/block/acpimmio/biosram.c
is only used on Stoneyridge and the old amd/southbridge code and not on
Picasso or Cezanne. It also only builds as a 32 bit binary and breaks
when trying to build as a 64 bit binary, since the size of an uintptr_t
is different on those two. There is no support for using the 32 bit
binaryPI with a 64 bit coreboot while there is code to use a 32 bit FSP
with 64 bit coreboot, so not building this for FSP-based SoC support
moves us one step closer to be able to build coreboot as 64 bit binary
for Picasso and Cezanne.

It appears the pspp_policy enum is not the same as the FSP definition
currently being used. This means that the incorrect PSPP value setting
would get read by FSP. For Zork programs this meant we actually were
setting links as DXIO_PSPP_BALANCED instead of DXIO_PSPP_POWERSAVE.
This change adds DXIO_PSPP_DISABLED as the first enum value to properly
match the FSP definition and adjusts non AMD Customer Reference Boards
that reference the enum to still send the same value even though it has
now change definitions. If we actually want DXIO_PSPP_POWERSAVE for
those boards that can be adjusted in a future change.

This CL adds a method that can start the processes of reading the APOB
from SPI. It does require more RAM in ramstage since we no longer mmap
the buffer in the happy path. This will allow us to reduce our
boot time by ~10ms. The SoC code will need to be updated to call
start_apob_cache_read at a point where it makes sense.
BUG=b:179699789
TEST=With this and the patches above I can see a 10 ms reduction in
boot time on guybrush.

Those registers are architectural MSR and this also gets them in line
with IA32_MC0_CTL and IA32_MC0_STATUS. Also move them below the
definitions for IA32_MC0_STATUS, so that the numbers of the MSRs are
ascending.

Since initial_lapicid() returns an unsigned int, change the type of the
local variables the return value gets assigned to to unsigned int as
well if applicable. Also change the printk format strings for printing
the variable's contents to %u where it was %d before.

Use the common mca_get_bank_count function instead of open-coding the

Allow hot plug devices to subscribe to IOMMU services. Currently the
IOMMU end range is limited to device B:0 D:1f F:6. This prevents the
devices on bus 1 and higher to subscribe to IOMMU services. As per AMD
IOMMU spec v3 section 5.2.2.1 all possible device IDs must be defined,
whether the device ID is actually populated or not. Device entries are
used to report ranges when hot-plug and SR-IOV devices are possible.
With this change the hot plug devices can now bind to IOMMU services
(as tested on kernel v5.4), and below errors are not seen in dmesg.
AMD-Vi: Event logged [IO_PAGE_FAULT device=04:00.3 domain=0x0000]
AMD-Vi: Event logged [IO_PAGE_FAULT device=05:00.0 domain=0x0000]
AMD-Vi: Event logged [IO_PAGE_FAULT device=04:00.4 domain=0x0000]
TEST= Verify dGPU can enumerate on hotplug. No IO page fault errors seen.
The hot plug devices can successfully bind to IOMMU services in
kernel.

The next patches will add support for the SPI DMA controller. This will

Introduce the `ARCH_ALL_STAGES_X86` Kconfig symbol to automatically
select the per-stage arch options. Subsequent commits will leverage
this to allow choosing between 32-bit and 64-bit coreboot where all
stages are x86. AMD Picasso and AMD Cezanne are the only exceptions
to this rule: they disable `ARCH_ALL_STAGES_X86` and explicitly set
the per-stage arch options accordingly.

The original reason the BERT table was moved out of CBMEM was because
the OS was not able to access the region. This happened because the
CBMEM region was marked as type 16 in the e820 table. The OS isn't aware
of this type, so it prevents any drivers from accessing it. Depthcharge
now correctly labels the CBMEM region as reserved in the e820 table so
we can move the BERT table into CBMEM.
TEST=BERT ACPI table generation still works on AMD/Mandolin with SeaBIOS
as payload and BERT region inside CBMEM is inside a BIOS-e820 reserved
range. BERT generation also works on Zork with depthcharge.
