63e7b70641 soc/amd/common/block/psp/psp_gen2: factor out pspv2_mbox_command union
The pspv2_mbox struct contained an unnamed union that covered the 32
bits of the command register of the PSP v2 mailbox. Since the pspv2_mbox
struct is mainly used for hardware register accesses and the union part
is mostly used to access the different bits before/after writing/reading
the command register, split this functionality. For the register access
a command field is added to the pspv2_mbox struct instead of the unnamed
union and for accessing the separate bits of the command register a new
named union is added.

81d0d89613 soc/amd/common/block/psp/psp_gen2: rename cmd_response to buffer
The cmd_response field in the pspv2_mbox struct is the buffer used to
pass data to the PSP and back to the x86 side, so rename it to buffer.
This also aligns the code a bit more with the reference code. Also
rename the wr_mbox_cmd_resp function to wr_mbox_buffer_ptr.

ed32977a39 soc/amd/common/block/i2c/i23c_pad_ctrl: only configure mode and voltage
The fch_i23c_pad_init implementation was written without looking at any
reference code and turned out to not work properly on hardware. Before
this function writes to the MISC_I23C_PAD_CTRL registers, the value read
back is 0x3000003c which results in the I2C bus communication to work
while the 0x300003fc the code writes to the register breaks the I2C
communication. Removing the code that sets bits 6..9 fixes the I2C bus
communication.

54786fece8 soc/amd/{common/vboot,cezanne}: Copy S0i3 verstage logs into cbmem
Now that SMM can write to CBMEM we can simply replay the transfer buffer
cbmem console to move it into the main cbmem console.

replay_transfer_buffer_cbmemc() relies on the EARLY_RAM linker symbols.
Since the SMM rmodule get linked with a different linker script than
bootblock/romstage it doesn't have access to these symbols. In order to
pass these symbols into SMM, we parse the bootblock.map file and
generate an early_ram.ld script. This script is then used when linking
SMM.

I replay the buffer in `smm_soc_early_init` because this call happens
before `console_init()`. `console_init()` prints the SMM header and we
want to append the verstage contents before printing the header to avoid
confusion.

BUG=b:221231786
TEST=Perform S0i3 cycles and verify PSP verstage logs now show up when

This patch aims to make timestamps more consistent in naming,

- TS_START_*/TS_END_*
- TS_BEFORE_*/TS_AFTER_*
- TS_*_START/TS_*_END
This change also aims to indicate, that these timestamps can be used
to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

282d715133 soc/amd/common/block/i2c: Add support for shared TPM_I2C controller
There are platforms equipped with AMD SoC where I2C3 controller
connected to TPM device is shared between X86 and PSP. In order to
handle this, PSP acts as an I2C-arbitrator, where x86 (kernel) sends
acquire and release requests to be accepted by PSP. An example of
implementation within Linux kernel is available [1].

There is a need to introduce new ACPI_ID ("AMDI0019") so that dedicated
driver on OS side can bind to it and handle this special setup. Since
PSP takes care of I2C controller power management, we need to remove
PowerResource object from DSDT.

The and-mask passed to the gpio_update32 call needs all 32 bits to be
set to ones. When building as 32 bit binary the -1UL will result in the
needed bit mask, but for a 64 bit build the constant would have 64 bits
set to ones which then gets truncated to 32 bits causing a compiler
error. Use 0xffffffff as bit mask instead which behaves correctly in
both cases and also clarifies what this is doing.

399d3cf878 soc/amd/common/include/ioapic: make IOAPIC IDs not depend on MAX_CPUS
Since the APIC bus isn't used since a long time and the IOAPIC and LAPIC
talk to each other via the system bus, there is no longer the
requirement that the IOAPIC IDs mustn't overlap with the LAPIC IDs that
start at 0 and end at CONFIG_MAX_CPUS - 1. The current Intel code uses 2
as the IOAPIC ID while most of their CPUs have more than 2 logical cores
resulting in the IOAPIC having the same ID as one of the LAPICs.

All chipsets in soc/amd use the defines for FCH_IOAPIC_ID and
GNB_IOAPIC_ID for initializing the IOAPIC register, writing both MADT
and IVRS ACPI tables and there's no MPTable support for those SoCs that
might also rely on those IDs being consistent.

This patch changes the definitions for FCH_IOAPIC_ID and GNB_IOAPIC_ID
from CONFIG_MAX_CPUS and CONFIG_MAX_CPUS + 1 to 0 and 1. This also makes
sure that the IOAPIC IDs still fit in 4 bits despite Cezanne having a
CONFIG_MAX_CPUS of 16 resulting in the IOAPIC IDs being larger than 4
bits with the old code. While the Cezanne FCH IOAPIC supports 8 bits of
IOAPIC IDs, this is non-standard.

TEST=AMD Mandolin and Google Liara still work.

1e25fd426a soc/amd/common/block/psp: introduce AMD_SOC_SEPARATE_EFS_SECTION
On systems that use the first 128kByte of the SPI flash for the EC
firmware, it is not possible to place the EFS/amdfw part at the lowest
location in flash where the on-chip PSP firmware will look for the EFS,
since this is at an offset of 128kByte into the flash which is where the
cbfs master header resides when the main CBFS is placed right after the
EC firmware. This patch introduces the AMD_SOC_SEPARATE_EFS_SECTION
option that allows putting the EFS in a separate FMAP section that can
be located right after the EC firmware FMAP section. The EFS FMAP
partition is checked to ensure it begins at the expected location.

421c7d1a99 soc/amd/common/block/include/psp_efs: update defines for sabrina
Document #55758 Rev. 1.13 says that family 17h models 30h-3Fh and later
use the spi_readmode_f17_mod_30_3f struct element for SPI_MODE_FIELD and
spi_fastspeed_f17_mod_30_3f for SPI_SPEED_FIELD, so also use this for
The AMD Sabrina SoC which is family 17h models A0h-AFh.

86302a806c soc/amd/{common,cezanne,picasso}: Add PRE_X86_CBMEM_CONSOLE_SIZE
This change splits the size of the console transfer region and size of
the bootblock/romstage Pre-RAM console region. This allows having a
larger Pre-RAM console while not impacting the size of the PSP verstage
console.

Instead of directly using the PRE_X86_CBMEM_CONSOLE_SIZE symbol in
`setup_cbmem_console`, I chose to use the offsets provided in the
transfer buffer. It would be nice to eventually do this for all the
fields in the transfer buffer.

espi_get_configuration returning CB_ERR, espi_get_configuration didn't
write to the local config variable, so if this happens in the first pass
of the do-while loop, the following espi_slave_is_channel_ready call
would use the uninitialized local config variable as parameter. Fix this
by checking the return value of espi_get_configuration.

6b0f45199c soc/amd/common/include/spi: add Cezanne-specific comment
The Cezanne PPR #56569 Rev 3.03 has one more SPI FIFO bytes defined
compared to the previous generations. It is unclear if adding some
special handling for Cezanne would be worth the effort, since the
current code just doesn't use the last byte which should be safe to do,
since this only affects the maximum number of bytes that can be used for
one SPI transaction. Having another byte to use on Cezanne wouldn't
reduce the number of SPI transactions to write a 256 byte data block.

According to https://uefi.org/specs/ACPI/6.4/04_ACPI_Hardware_Specification/ACPI_Hardware_Specification.html#pm1-event-grouping

> For ACPI/legacy systems, when transitioning from the legacy to the G0

This means we don't want to clear the PM1 register on resume. By
clearing it the linux kernel can't correctly increment the wake count
when the power button is pressed. The AMD platforms implement the _SWS
ACPI methods, but the linux kernel doesn't actually use these methods.

f6205d3deb soc/amd/common/block/lpc: use 32 bit accesses in lpc_enable_port80
When using 32 bit PCI accesses in lpc_enable_port80, we can use the
LPC_IO_OR_MEM_DECODE_ENABLE and DECODE_IO_PORT_ENABLE4 defines and don't
need to re-define bits with offsets from the beginning of the third byte
within this 32 bit register. This allows to drop the
LPC_IO_OR_MEM_DEC_EN_HIGH register definition which points to
LPC_IO_OR_MEM_DECODE_ENABLE + 2 and to drop the re-definitions of the
bit re-definitions with a different offset.

The code in lpc_enable_port80 was originally copied from sb/amd/agesa/
hudson/early_setup.c which might be sort-of a copy from what the AGESA
reference code does.

The corresponding bit is marked as reserved in the following versions of
the documentation for all SoCs using this code:

Mullins: BKDG #52740 Rev 3.05
Stoneyridge: BKDG #55072 Rev 3.04
Raven1, Picasso: PPR #55570 Rev 3.16 & 3.18
Raven2: PPR #55772 Rev 3.08
Cezanne: PPR #56569 Rev 3.03

The old Rev 3.14 of the Picasso PPR #55570 had the bit 19 defined as
PullUpSel, but this is no longer the case in newer versions. It is
unclear if this got de-featured or if it was never present in the
silicon. To be consistent with the current documentation, drop this
define.

This patch also change the definition of GPIO_PULL_MASK to only cover
the bits used for the feature. The Cezanne PPR #56569 Rev 3.03 states a
default value of 0 for this bit after reset, so the resulting values in
the register aren't expected change. The other PPRs/BKDGs don't specify
a reset value for this bit, but it's likely safe to assume that all SoCs
that use the new GPIO interface use the same GPIO building block.

571e7f02de lib/prog_loaders, soc/amd/: Make payload_preload use cbfs_preload
Now that CBFS has this functionality built in, we no longer need to
manually code it.

payload_preload used to use the payload_preload_cache region to store
the raw payload contents. This region was placed outside the firmware
reserved region, so it was available for use by the OS. This was
possible because the payload isn't loaded again on S3 resume.

cbfs_preload only uses the cbfs_cache region. This region must be
reserved because it gets used on the S3 resume path. Unfortunately this
means that cbfs_cache must be increased to hold the payload. Cezanne is
the only platform currently using payload_preload, and the size of
cbfs_cache has already been adjusted.

In the future we could look into adding an option to cbfs_preload that
would allow it to use a different memory pool for the cache allocation.

BUG=b:179699789
TEST=Boot guybrush and verify preloading the payload was successful

issue due to renaming of existing macros due to scoping the Memory
Type.
2. Use dedicated Memory Type and Module type for `Form Factor`
and `TypeDetail` conversion using `get_spd_info()` function.
3. Create a new API (convert_form_factor_to_module_type()) for
`Form Factor` to 'Module type' conversion as per `Memory Type`.
4. Add new argument as `Memory Type` to
smbios_form_factor_to_spd_mod_type() so that it can internally
call convert_form_factor_to_module_type() for `Module Type`
conversion.
5. Update `test_smbios_form_factor_to_spd_mod_type()` to
accommodate different memory types.
6. Skip fixed module type to form factor conversion using DDR2 SPD4
specification (inside dimm_info_fill()).

82faefb339 cpu/x86/mp_init: use cb_err as status return type in remaining functions
Using cb_err as return type of mp_run_on_aps, mp_run_on_all_aps,
mp_run_on_all_cpus and mp_park_aps clarifies the meaning of the
different return values. This patch also adds the types.h include that
provides the definition of the cb_err enum and checks the return value
of all 4 functions listed above against the enum values instead of
either checking if it's non-zero or less than zero to handle the error
case.

Before this patch, gpio_configure_pads_with_override called
program_gpios once for each GPIO that needed to be configured which
resulted in base_num_pads - 1 unneeded master_switch_set/
master_switch_clr sequences for the gpio_configure_pads_with_override
call. Instead implement gpio_configure_pads_with_override as the more

passes an empty override configuration and override pad number to
gpio_configure_pads_with_override.

b4fe8c5948 soc/amd/common/block/gpio_banks: add remote GPIO support
Some AMD SoCs have a 5th GPIO bank, the remote GPIO bank, which isn't
located right after the 4th GPIO bank, but instead at a different
location inside the APCIMMIO region. A difference to the first 4 GPIO
banks is that the corresponding GPIO MUX registers aren't in a separate
bank, but at the end of the remote GPIO region. So this remote GPIO
region only supports 48 GPIOs with a 32 bit configuration register each
and has the 8 bit GPIO MUX registers beginning at offset 0xc0 in the
remote GPIO region.

For now using the remote GPIOs from verstage on PSP isn't supported. To
support this, it would need to map acpimmio_remote_gpio and update the
pointer like it already does for acpimmio_gpio0, acpimmio_iomux and a
few others.

96c4882d25 soc/amd/common/block/i2c: use common GPIO API in drive_scl
No need to do raw GPIO MMIO accesses when basically the same
functionality can be achieved by using existing APIs. Using the existing
GPIO API instead of raw GPIO MMIO register accesses allows containing
all direct GPIO MMIO accesses inside the common AMD GPIO code which will
be done in subsequent patches. Since the value parameter of gpio_set is
int, change the type of the val parameter of drive_scl to int as well
even though I'm not sure why a signed integer was used for this in the
common GPIO API. Since program_gpios already configures the SCL GPIOs as
outputs, gpio_set can be used in drive_scl which only sets the output
value, but doesn't configure the direction.

TEST=The waveform on the SCL pin of I2C3 on a barla/careena Chromebook
looks similar to the same as before during the reset_i2c_peripherals
call, but due to the additional overhead of the read-modify-write to the
GPIO register instead of just a write, the pulse width gets about 50%
longer. Since the udelay call in drive_scl still has an open TODO to
make this configurable and the pulses being longer is in the safe side,
this side-effect can be addressed in a follow-up patch.

8d268e9bda soc/amd/common/fsp/fsp_validate: add runtime check for FSP-M binary size
When modules are added to the FSP and they won't fit into the FSP binary
any more, the size can be increased in the FSP build. Especially in the
case of debug builds the increased size might not fit into the memory
region it gets decompressed into which starts at FSP_M_ADDR and has a
size of FSP_M_SIZE. SoCs can implement the soc_validate_fspm_header
function that ends up being called by the FSP driver in romstage to do
some additional checks on the FSP binary's header that includes the
version number and the image size. We can use the image size field to
check if it fits into the reserved region. Since the FSP-M memory region
is located after romstage loading it won't clobber the romstage code
where we do the check.

This runtime check is added in addition to the build-time check to also
cover the case when the FSP binaries in CBFS get replaced with ones that
don't fit into the reserved memory region after the coreboot build.

BUG=b:186149011
TEST=Mandolin still boots fine with the patch applied. When as a test
the FSP_M_SIZE Kconfig option in soc/amd/picasso is decreased to 0x10000
which is by far not enough for the decompressed FSP-M binary to fit into
it prints the newly added error message on the console and then stops.

e44dad3096 soc/amd/common/fsp/Makefile: check if FSP-M is larger than FSP_M_SIZE
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.

b90e6fdd25 soc/amd/common: Skip psp_verstage on S0i3 resume
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

90ac882a32 soc/amd/common/block/spi: introduce SOC_AMD_COMMON_BLOCK_SPI_4DW_BURST
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.
