While the SoC-level defaults for VGA_BIOS_ID are the expected correctly
remapped PCI VID/PID of the GPU which matches the PCI VID/DID inside the
VBIOS file, some mainboards override the VGA_BIOS_ID setting to the
non-remapped PCI ID. This resulted in coreboot not finding the VBIOS
file after commit 42f0396a10 ("device/pci_rom: rework PCI ID remapping
in pci_rom_probe"). The proper solution would be to not override this
SoC-level config in neither the mainboard code nor some external config
file. This however requires adding/using some mechanism to tell SeaBIOS
which VBIOS image to use for the GPU device. Once this is implemented,
the SoC default for VGA_BIOS_ID shouldn't be overridden any more and
this patch can be reverted again.
This sort-of reverts parts of commit 42f0396a10 ("device/pci_rom:
rework PCI ID remapping in pci_rom_probe"), but it still tries to find
the VBIOS image with the expected remapped PCI ID and only adds trying
the non-remapped PCI ID as a fallback when the file with the remapped
PCI ID doesn't exist and prints a notice in that case. Before the patch
referenced above, using the correct remapped PCI VID/DID resulted in a
warning about the CBFS file with the non-remapped name not being found,
but first checking the remapped version solves that problem.

The CHECK_REV_IN_OPROM_NAME Kconfig option was introduced to solve the
problem of the PCI VID/DID combination of the Picasso iGPU not being
sufficient information to know which VGA BIOS file to run, so a new
function that additionally checks the PCI revision of that device was
introduced. Later it turned out that there might be a case where even
that isn't sufficient, so the soc_is_raven2() function is used in the
remap function to always use the correct VBIOS file.
Picasso is the only SoC that selected the CHECK_REV_IN_OPROM_NAME
Kconfig option, so all other SoCs are unaffected by this change.
Now that we use the VBIOS images with only the PCI VID and DID in the
CBFS file name for Picasso, SeaBIOS will find the VBIOS with the same ID
as the iGPU in CBFS and we don't need the workaround to add a third
VBIOS image via VGA_BIOS_DGPU_* that has the name that SeaBIOS expects.
This will result in SeaBIOS now running the VBIOS that has the same PCI
VID/DID as the hardware which will be the wrong one in the RV2 silicon
showing the PCO silicon PCI VID/DID, but that was also the case with the
VGA_BIOS_DGPU_* workaround where the board's Kconfig just selected one
of the two possible images during build time and hoped that it was the
correct one for that actual hardware. The only board where this patch
might cause a regression compared to the old behavior is the AMD Cereme
reference board with Pollock APU, but I'm not even sure if any coreboot
developer still has one of those boards, so I'm willing to accept that.
To properly solve the problem with SeaBIOS using the correct VBIOS file
in all cases, we'd need to generate that info during coreboot runtime
and somehow pass it to SeaBIOS, but that's out of scope for this patch.
TEST=On Mandolin with PCO silicon, the display output in both SeaBIOS
and Ubuntu still works. Booting Windows 10 via the pre-built EDK2
payload that I'm using also resulted in the display output working.

Current implementation assumes that the endpoint device is connected
directly to the PCIe Root Port, which does not always have to be true.
In a case where there is a PCIe switch between the endpoint and the
root port, the Max Payload Size capability may differ across the
devices in the chain and coreboot will not set a correct Max Payload
Size. This results in a PCIe device malfunction in pre-OS environment,
e.g. if the Ethernet NICs are connected behind a PCIe switch, the iPXE
fails to obtain the DHCP configuration.
Fix this by traversing the topology and programming the highest common
Max Payload Size in the given PCIe device chain during enumeration.
Once finished, the root port has the highest common Max Payload Size
supported by all the devices in the chain. So at the end of root port
bus scan, propagate the root port's Max Payload Size to all downstream
devices to keep Max Payload Size in sync within the whole chain.

Historically resource allocation in coreboot was 32bit x86 thing. To
remain compatible with this behavior (e.g. to keep 32bit payloads
happy), resource allocation limits resources to 32 bits unless
explicitly overridden. However this behavior is not always appropriate:
e.g. on non x86 platforms the PCIe mem decode window could be above 4G.
Another case on x86 is where the decode window(s) below 4G are not
adequate for fitting all resources and the payload is 64bit
capable (e.g. Linux).
This adds a Kconfig flag to override the behavior to limit resources to
32bit by default and to allocate resources according to the real
hardware limits.

The physical address size of the System-on-Chip (SoC) can be different

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

To help identify the licenses of the various files contained in the
coreboot source, we've added SPDX headers to the top of all of the
.c and .h files. This extends that practice to Makefiles.
Any file in the coreboot project without a specific license is bound
to the license of the overall coreboot project, GPL Version 2.
This patch adds the GPL V2 license identifier to the top of all
makefiles in the commonlib, console, northbridge, security, and
southbridge directories that don't already have an SPDX license line
at the top.

EDK2 seems to have problems at least with the resource allocation for
Intel's IGD. While the investigation is ongoing, disable top-down
allocation by default if the payload is known to be EDK2.

The prefix POSTCODE makes it clear that the macro is a post code.
Hence, replace related macros starting with POST to POSTCODE and
also replace every instance the macros are invoked with the new
name.
The files was changed by running the following bash script from the
top level directory.
sed -i'' '30,${s/#define POST/#define POSTCODE/g;}' \
src/commonlib/include/commonlib/console/post_codes.h;
myArray=`grep -e "^#define POSTCODE_" \
