This southbridge can route POST codes written to port 0x80 to either
LPC or PCI, but currently always route them to LPC. Change it so that
POST codes are routed to PCI if CONFIG(POST_DEVICE_PCI_PCIE) is
selected, LPC otherwise.
Rename the static function because POST codes no longer always go to
LPC.

This patch follows the BWG recommendation (doc 729123) by clearing
the SPI SYNC_SS bit before disabling the WPD bit in
SPI_BIOS_CONTROL. This prevents boot hangs due to a 3-strike error.
Unable to follow this guideline would result into boot hang
(3-strike error).

The physical address size of the System-on-Chip (SoC) can be different
from the CPU physical address size. These two different physical
address sizes should be used for settings of their respective field.
For instance, the physical address size related to the CPU should be
used for MTRR programming while the physical address size of the SoC
should be used for MMIO resource allocation.
Typically, on Meteor Lake, the CPUs physical address size is 46 if TME
is disabled and 42 if TME is enabled but Meteor Lake SoC physical
address size is always 42. As a result, MTRRs should reflect the TME
status while coreboot MMIO resource allocator should always use
42 bits.
This commit introduces `SOC_PHYSICAL_ADDRESS_WIDTH' Kconfig to set the
physical address size of the SoC for those SoCs.

With earlier flow, a chunk of CBMEM region was allocated for each SRAM
e.g., PUNIT SRAM, SOC PMC SRAM and IOE PMC SRAM. Then entire SRAM
content was copied to dedicated CBMEM region. Later in acpi_bert.c, the
BERT table was getting created for each chunk of CBMEM. This flow was
not considering creating separate entries for each region of crashlog
records. It resulted in only the first entry getting decoded from each
SRAM.
New flow aims to fix this issue. With new flow, a simple singly linked
list is created to store each region of crashlog records from all
SRAMs. The crashlog data is not copied to CBMEM. The nodes are
allocated dynamically and then copied to ACPI BERT table and then
freed. This flow also makes the overall crashlog code much simpler.

As we look at unifying the format of coreboot code (/src, excluding
src/vendorcode), we need a code-beautifier configuration that works
well with the coreboot style. This patch is an attempt to match the
existing code styles as much as possible.
There are going to be some trade-offs in any code formatter. Tables
which have been hand-formatted probably won't look as good. These
can be specifically marked to be excluded from the formatter, however
this should be the exception, not the rule.
