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.

forgot to actually make it do that. This patch fixes that.
Since there is no more use case for do_cbfs_locate() having to figure
out the file size on its own, and that generally seems to be a bad idea
(as the original issue shows), also remove that part of it completely

The OEM may create and sign an Audio component to extend the Audio

signature and public key are entered into the header of the manifest
to create the final signed component binary. This creates a secure

Manifest was signed with a key owned by a trusted owner. Once OEM KM
is authenticated, each public key hash stored within the OEM KM is

In cbfs_add_component(), the |offset| variable confusingly jumps back
and forth between host address space and flash address space in some
cases. This patch tries to clean that logic up a bit by converting it
to flash address space very early in the function, and then keeping it
that way afterwards. convert() implementations that need the host
address space value should store it in a different variable to reduce
the risk of confusion. This should also fix a tiny issue where
--gen-attribute might have previously encoded the base address as given
in CBFS -- it probably makes more sense to always have it store a
consistent format (i.e. always flash address).
Also revert the unnecessary check for --base-address in
add_topswap_bootblock() that was added in CB:59877. On closer
inspection, the function actually doesn't use the passed in *offset at
all and uses it purely as an out-parameter. So while our current
Makefile does pass --base-address when adding the bootblock, it actually
has no effect and is redundant for the topswap case.

coreboot will interpret port numbers as 0 and 2, but since only 2 ports
are enabled in the system EC will assign port numbers as 0 and 1.
This creates a port number mismatch while communicating between EC and
coreboot. This patch addresses issue where SoC can implement function
to map correct EC port as per port enabled in mainboard.
BUG=b:207057940
BRANCH=None
TEST=Check if code compiles successfully. Functionality will work once
function is implemented in SoC code.

For additional power savings during RTD3, the PMC can power-gate the
ModPHY lanes that are used by the PCH PCIe root ports. Therefore,
using the previous PCIe RP-type detection functions, implement ModPHY
PG support for the PCH PCIe RPs.
This involves:
1) Adding a mutex so only one power resource accesses the PMC registers
at a time
2) OperationRegions to access the PMC's PG registers
3) Adding ModPHY PG enable sequence to _OFF
4) Adding ModPHY PG disable sequence to _ON
