ddf137f822 nb,soc/amd/*/iommu: fix comment about IOMMU MMIO resource
This comment was added with the AMD family 15h Trinity IOMMU support in
commit 88ebbeb7e2 and looks like a copy of
the comment about the subtractive decode ranges in the LPC device. The
IOMMU doesn't have any subtractively decoded I/O or MMIO ranges and this
is also not what the code does. This resource is the MMIO region to
configure the IOMMU instead, so fix the comment in all copies of the
IOMMU support code.

6c170e6b3c soc/amd/common/include/acpimmio: drop 16 and 32 bit PM2 access functions
The PM2 ACPIMMIO region should only be accessed with 8 bit accesses.
Using 16 or 32 bit read accesses will return the data from the first
byte for all 2 or 4 bytes and 16 or 32 bit write accesses will result in
only the first byte being written which is both unexpected behavior.

e5592d3d99 soc/amd/common/block/acpimmio/print_reset_status: extend bit name table
Bit 23 in the PM_RST_STATUS register is called LtReset on Stoneyridge
and ShutdownMsg on Picasso/Cezanne/Sabrina. Bit 30 is reserved on
Stoneyridge and defined as SdpParityErr on the newer SoCs. Bit 31 is
only defined for Sabrina. Since the default value of undefined bits is 0
it isn't a problem to have descriptions for reserved reset status bits
on some SoCs.

3bdbdb77a2 soc/amd/common/block/i2c/i23c_pad_ctr: add & use I23C pad configuration
I2C bus 0..2 on Sabrina uses a different pad type which supports 1.1V
and 1.8V levels, but doesn't support 3.3V I2C levels. Compared to the
existing I2C pad control registers the bit definitions are different, so
add a separate function to configure those pads which however still has
the same function signature and is compatible with same data structs
used for the devicetree settings. PPR #57243 Rev 1.50 was used as a
reference.

TEST=None

556d1cc17f soc/amd/*/i2c: factor out common I2C pad configuration
The I2C pad control registers of Picasso and Cezanne are identical and
the one of Sabrina is a superset of it, so factor out the functionality.
To avoid having devicetree settings that contain raw register bits, the
i2c_pad_control struct is introduced and used. The old Picasso code for
this had the RX level hard-coded for 3.3V I2C interfaces, so keep it
this way in this patch but add a TODO  for future improvements.

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.

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.

> 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.
