Instead of including globalnvs.asl in the mainboard's dsdt.asl, include
it in Genoa's soc.asl. This aligns Genoa with Cezanne and newer and also
moves more SoC-common code to the SoC folder.

Earlier entire SPI ROM was mapped to memory. With limited TLB resources
in PSP, this approach hit the limit on systems using 32 MiB SPI ROM.
Therefore regions in SPI ROM were mapped on need basis. This works well
on Picasso, Mendocino and Phoenix SoCs. But unfortunately this causes
boot hangs in Cezanne SoC. Add a configuration to map the entire SPI ROM
and enable it in Cezanne SoC. For other SoCs, keep the configuration
disabled so that only the required SPI ROM region is mapped.

The Genoa SoC has 6 I2C controllers. In order to support those, select
SOC_AMD_COMMON_BLOCK_I2C and implement the SoC-specific functions and
data structures needed by the common AMD I2C code. Since the common AMD
I2C code also reports if the controller is enabled or not in the SSDT,
change the corresponding DSDT code to use this information. In this
patch the I2C pad control registers don't get configured by coreboot yet
and we rely on ABL already having those set up correctly which seems to
be an assumption that the reference firmware is making too. PPR #55901
Rev 0.26 was used as a reference for the I2C controllers and the GPIO
pins being used.

Drop the hda_soc_ssdt_quirks function since it doesn't apply for any of
the SoCs supported by the Stoneyridge code which was the only SoC
implementing it. This code was added when commit 91a7abf25c72
("soc/amd/hda: Move HDA PCI device from DSDT to SSDT") rewrote the code
originally added in commit 1587dc8a2b4d ("soc/amd/stoneyridge: Add
northbridge support") as a copy from northbridge/amd/pi/00670F00. This
code was moved around in commit 6580408a7e0a ("amd/pi/hudson: Move audio
to northbridge"), since the HDA controller was moved from the FCH to the
northbridge complex. When the controller was moved, the PCI config space
interface also changed, so those bits are no longer the DisableNoSnoop,
DisableNoSnoopOverride, and EnableNoSnoopRequest bits of the Misc
Control register of the HDA controller, but some bits within the
ClassCodeW field of the ACGAZ Mirrot Reg Ctrl 0 register.
BKDG #55072 Rev 3.04 (Stoneyridge), BKDG #50742 Rev 3.08 (family 15h
model 60h-6fh / 00670F00), and BKDG #52740 Rev 3.05 (family 16h model
30h-3fh) were used as a reference. Only the SoC with BKDG #52740 still
has the HDA controller in the FCH; the other two have it in the
northbridge.

This reverts commit 44a48ce7a46c36df69f7b2cf3552bf10fa5f61b6.
Reason for revert: It breaks wakeup from suspend on a bunch of boards.
While this approach of eyeballing "correct" values by chipset _should_
be fixed, it should also be accompanied by compile time verification
that the memory map works out.
Since nobody seems to care enough, let's just revert this, instead of
keeping the tree broken for a bunch of configurations.

Commit e728766f4596 ("soc/amd/mendocino: Do not load MP2 Firmware when
in RO") added logic to ensure that the MP2 disable soft fuse bit was set
for the RO section, but failed to check if the bit was already set
otherwise (as it is for non-ChromeOS builds). This caused the bit to
appear twice in the PSP_RO_SOFTFUSE_BITS string, and when the string
was converted to a series of numeric values and added together, bit
(n+1) ended up being set instead of bit n.
To mitigate this, use the makefile sort() function to ensure the
PSP_[RO_]SOFTFUSE_BITS string does not contain any duplicates before
the bitmask is calculated. Apply this to all AMD SoC makefiles where
the softfuse bits are added.
TEST=build/boot google/skyrim (frostflow). Use a verbose build (V=1)
to verify that the correct soft fuse value is passed to amdfwtool for
RO and RW_A/B for both ChromeOS and non-ChromeOS builds.

Move all security patch level (SPL) related Kconfig options to the
common AMD PSP Kconfig file. Commit 4ab1db82bb30 ("soc/amd: rework SPL
file override and SPL fusing handling") already reworked the SPL
handling, but missed that another Kconfig option
SOC_AMD_COMMON_BLOCK_PSP_FUSE_SPL controlled if the PSP mailbox command
to update the SPL fuses was sent by the code that got added to the build
when PERFORM_SPL_FUSING was selected.
To make things less unexpected, rename PERFORM_SPL_FUSING to
SOC_AMD_COMMON_BLOCK_PSP_SPL since it actually controls if the SPL
support code is added to the build and also rename
SOC_AMD_COMMON_BLOCK_PSP_FUSE_SPL to PERFORM_SPL_FUSING. This changes
what PERFORM_SPL_FUSING will do from including the code that could do
the fusing if another option is set to being the option that controls if
the fusing mailbox command will be set. All SoCs that support SPL now
select SOC_AMD_COMMON_BLOCK_PSP_SPL in their Kconfig, which won't burn
any SPL fuses.
The logic in the Skyrim mainboard Kconfig file is reworked to select
PERFORM_SPL_FUSING for all boards on which the SPL fuses should be
updated; on Guybrush PERFORM_SPL_FUSING default is changed to y for all
variants. The option to include the code that checks the SPL fusing
conditions and allows sending the command to update the SPL fuses if the
corresponding Kconfig is set doesn't need to be added on the mainboard
level, since it's already selected at the SoC level.

Supports a brand new ACP driver for STONEY / Grunt chromebooks.
AMD's Audio CoProcessor handles i2s/tdm audio, and is located on the
GPU.
On Windows the PCIe device for the GPU is owned by the AMD proprietary
driver, hence a separate device has to be added for the ACP driver.
Fortunately since IOMMU is disabled on STONEY, the driver itself can
pull BAR5 from the GPU and use that to initialize, so no special
configuration is required in ACPI other than the ID.

Update the filename for the PSP_SMUFW2_SUB1_FILE to use the compressed

version (.sbin), in order to be consistent with the other SMU firmware
files. This will also facilitate dropping the duplicate files in an
upcoming update to the amd_blobs repo and updating the SMU files (all
of which are .csbin).
This change is actually a no-op since the .csbin and .sbin are the same
file; it appears that the .sbin file was incorrectly named when added,
and then the same file was added later with the correct extension.

especially with CBFS verification enabled. Also with RW CBFS
verification enabled, the entire firmware body is not loaded during
verstage for verification. Instead the files are verified as and when

Having a CBFS cache scratchpad offers a generic way to decompress CBFS
files through the cbfs_map() function without having to reserve a
per-file specific memory region.
This commit introduces the x86 `PRERAM_CBFS_CACHE_SIZE' Kconfig to set
the pre-memory stages CBFS cache size. A cache size of zero disables
the CBFS cache feature. The default value is 16 KB which seems a
reasonable minimal value enough to satisfy basic needs such as the
decompression of a small configuration file. This setting can be
adjusted depending on the platform needs and capabilities.
We have set this size to zero for all the platforms without enough
space in Cache-As-RAM to accommodate the default size.

Crypto Engine in PSP prefers the buffer from Static RAM (SRAM). Hence if
a buffer comes from within SRAM address range, then it is passed
directly to Crypto Engine. Otherwise a bounce bufer from the stack is
used. But on SoCs like Picasso where PSP Verstage stack is mapped to a
virtual address space this check fails causing a bounce buffer to be
used and hence a stack overflow. Fix this issue by assuming that the
buffer comes from the SRAM always in such SoCs and pass the buffer
directly to crypto engine.

We have a tiny HEAP_SIZE by default, except when we don't, and
mainboards that override it, or not.
Since memory isn't exactly at a premium these days, and unused heap
doesn't cost anything extra, just crank it up to the highest value
we have in the tree by default and remove all overrides.

Commit 26d54b70e282 ("soc/amd/common/cpu: use TSC_MONOTONIC_TIMER for
SOC_AMD_COMMON_BLOCK_TSC") updated all the AMD SoCs with Zen-based CPU
cores to use TSC_MONOTONIC_TIMER. The same change adjusted the PSP
Verstage timestamps (in microseconds) to the x86 TSC rate. But it
included only the base_time during the adjustment leaving the individual
entry timestamp. This leads to incorrectly adjusted PSP Verstage
timestamps. Fix the adjustment logic.
BUG=None
TEST=Build and boot to OS in Skyrim. Ensure that the PSP Verstage
timestamps in cbmem -t output are adjusted correctly.

The SPL_TABLE_FILE and SPL_RW_AB_TABLE_FILE Kconfig options provide a
way to override the default SPL file configured in the SoC's fw.cfg file
by passing the '--spl-table' parameter to amdfwtool which will then use
the override instead of the SPL file from the fw.cfg file. When
SPL*_TABLE_FILE is an empty string, the corresponding add_opt_prefix
call in the makefile will result in no '--spl-table' parameter being
passed to amdfwtool, so it'll use the default SPL file from fw.cfg. In
order to not pass an SPL override by default, remove the default from
the SPL_TABLE_FILE in the SoC's Kconfig. The SoC default pointed to the
same SPL file as in fw.cfg file anyway. Now only when a mainboard sets
this option to point to a file, that file will be used as an override.
This override is used to include a special SPL file needed for the
verstage on PSP case on the Chromebooks. Since SPL_TABLE_FILE is an
empty string by default, neither the SPL_TABLE_FILE Kconfig option nor
it being evaluated in the Makefile need to be guarded by HAVE_SPL_FILE,
so remove the dependency in the Kconfig and the ifeq in the Makefile.
Before this patch, the HAVE_SPL_FILE option controlled two things that
shouldn't be controlled by the same Kconfig option: Only when
HAVE_SPL_FILE was set to y, the SPL_TABLE_FILE override was taken into
account, and it also controls if spl_fuse.c got added to the build which
when added will send the SPL fusing command to the PSP. So the case of
needing an SPL file override, but not updating the SPL fuses wasn't
supported before.
The SPL file in the amdfw part will be used by the PSP bootloader for
the anti-rollback feature which makes sure that the SPL file version
isn't lower than what is in the SPL fuses. For this the SPL file needs
to be present in the PSP directory table. The SPL version check happens
way before we're running code on the x86 cores. The SPL fusing PSP
command that can be sent by coreboot will tell the PSP to update the SPL
fuses so that the fused minimal SPL version will be updated to the
current SPL version.
Since the former HAVE_SPL_FILE option now only controls if the SPL
fusing command will be sent to the PSP mailbox, rename it to
PERFORM_SPL_FUSING to clarify what this will do and update the help text
correctly describe what this does.
TEST=With INCLUDE_CONFIG_FILE set to n, timeless builds for both Birman
with Phoenix APU and Skyrim result in identical binaries.

Instead of having the get_usable_physical_address_bits function that
only got used in the data fabric domain resource reporting code, drop
this function, select RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT in the
common AMD non-CAR CPU and rename get_sme_reserved_address_bits to
get_reserved_phys_addr_bits so that the common cpu_phys_address_size
function will return the correct number of usable physical address bits
which now can be used everywhere. The common AMD CAR CPU support is only
selected by Stoneyridge which doesn't support secure memory encryption,
so RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT isn't selected by the
SOC_AMD_COMMON_BLOCK_CAR Kconfig option.
Before only the MMIO region reporting took the reserved physical address
bits into account, but now also the MTRR calculation will take those
reserved bits into account. See the AMD64 Programmers Manual volume 2
(document number 24593) for details. Chapter 7.10.5 from revision 3.41
of this document was used as a reference. The MTRR handling code in
older Linux kernels complains when the upper reserved bits in the MTRR
mask weren't set, but sets them after complaining and then continues to
boot. This issue is no longer present in version 6.5 of the Linux
kernel.
The calculation of the TSEG mask however still needs to take all
physical bits into account, including the ones reserved for the memory
encryption. When not setting the reserved bits in the TSEG mask, the
Mandolin board with a Picasso APU won't boot to the OS any more due to
not returning from SeaBIOS calling into the VBIOS. Haven't root-caused
what exactly causes this breakage, but I think previously when something
else was wrong with the SMM initialization, also something went wrong
when calling into the VBIOS.
TEST=Ubuntu 2023.10 nightly build boots on Mandolin via SeaBIOS and EDK2
and Windows 10 boots on it via EDK2.
TEST=On Ubuntu 2022.04 LTS, the kernel complained with the following
warning, but it still continues the boot process as described above:
mtrr: your BIOS has configured an incorrect mask, fixing it.

result developers are required to include runtime initialization code
instead of relying on C global variable definition.
To illustrate the impact of this lack of `.data` section support, here
are two limitations I personally ran into:
1. The inclusion of libgfxinit in romstage for Raptor Lake has
required some changes in libgfxinit to ensure data is initialized at
runtime. In addition, we had to manually map some `.data` symbols in
the `_bss` region.
2. CBFS cache is currently not supported in pre-memory stages and
enabling it would require to add an initialization function and
find a generic spot to call it.
Other platforms do not have that limitation. Hence, resolving it would
help to align code and reduce compilation based restriction (cf. the
use of `ENV_HAS_DATA_SECTION` compilation flag in various places of
coreboot code).
We identified three cases to consider:
1. eXecute-In-Place pre-memory stages
- code is in SPINOR
- data is also stored in SPINOR but must be linked in Cache-As-RAM
and copied there at runtime
2. `bootblock` stage is a bit different as it uses Cache-As-Ram but
the memory mapping and its entry code different
3. pre-memory stages loaded in and executed from
Cache-As-RAM (cf. `CONFIG_NO_XIP_EARLY_STAGES`).
eXecute-In-Place pre-memory stages (#1) require the creation of a new
ELF segment as the code segment Virtual Memory Address and Load Memory
Address are identical but the data needs to be linked in
cache-As-RAM (VMA) but to be stored right after the code (LMA).
Here is the output `readelf --segments` on a `romstage.debug` ELF
binary.
Program Headers:
Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align
LOAD 0x000080 0x02000000 0x02000000 0x21960 0x21960 R E 0x20
LOAD 0x0219e0 0xfefb1640 0x02021960 0x00018 0x00018 RW 0x4
Section to Segment mapping:
Segment Sections...
00 .text
01 .data
Segment 0 `VirtAddr` and `PhysAddr` are at the same address while they
are totally different for the Segment 1 holding the `.data`
section. Since we need the data section `VirtAddr` to be in the
Cache-As-Ram and its `PhysAddr` right after the `.text` section, the
use of a new segment is mandatory.
`bootblock` (#2) also uses this new segment to store the data right
after the code and load it to Cache-As-RAM at runtime. However, the
code involved is different.
Not eXecute-In-Place pre-memory stages (#3) do not really need any
special work other than enabling a data section as the code and data
VMA / LMA translation vector is the same.
TEST=#1 and #2 verified on rex and qemu 32 and 64 bits:
- The `bootblock.debug`, `romstage.debug` and
`verstage.debug` all have data stored at the end of the `.text`
section and code to copy the data content to the Cache-As-RAM.
- The CBFS stages included in the final image has not improperly
relocated any of the `.data` section symbol.
- Test purposes global data symbols we added in bootblock,
romstage and verstage are properly accessible at runtime
#3: for "Intel Apollolake DDR3 RVP1" board, we verified that the
generated romstage ELF includes a .data section similarly to a
regular memory enabled stage.
