With commits 9987534 [southbridge/intel: Remove leftover TPM ACPI code]
and 66ce18c [soc/intel: Remove legacy static TPM asl code] removing
TPM ASL code from the southbridge's LPCB device, the LPC TPM chip driver
(drivers/pc80/tpm) must be added to devicetree in order to ensure the
new acpigen code is used to replace it.
Test: boot various google/samsung boards, verify SSDT created with
LPBC.TPM device and TPM visible to and usable by SeaBIOS and Linux

This effectively means it is possible to run another bootblock located at
top_of_flash - 64K.
The i82801gx southbridge has the ability to swap the two top 64K ranges by
flipping the BUC.TS bit (RCBA[3414] bit0).
This allows coreboot to build roms with a bootblock at the top swap offset by
selecting CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK.

Change f849972 (security/vboot: Enable TCPA log extension) enabled
support for adding TCPA log to CBMEM. However, if CBMEM is not online,
this function doesn't do anything and returns early. This condition is
not really a valid error condition as it depends on when the call to
tcpa_log_add_table_entry is made. Since tcpa_log_add_table_entry
returns -1 when cbmem is not online, tpm_extend_pcr prints an error
message with prefix "ERROR:". This can confuse any scripts trying to
catch errors in boot flow.
This CL makes the following changes:
1. Removes the print in tpm_extend_pcr since tcpa_log_add_table_entry
already prints out appropriate ERROR messages in case of failure to
add log entry.
2. Since the return value of tcpa_log_add_table_entry is not used
anymore, return type for tcpa_log_add_table_entry is changed to void.

the smm relocation code relies on some southbridge functions provided

This also caches the TSEG region and therefore increases MTRR usage a

This change primarily moves the PowerResource up to a more common scope so
that the _PRx references are simpler. The ^ scope modifier isn't well
supported everywhere amongst OSes and drivers. Windows 10 will BSOD
early during boot with ACPI_BIOS_ERROR (code 0x6, which means it could
not find the object referenced by a _PRx) with the way things are currently
laid out).
I've also not seen a firmware outside of coreboot that tries to reference
count _ON and _OFF. Isn't it up to the OS to deference count, and whatever
it tells ACPI is what should happen (i.e., on means on and off means off)?
Some of the _UIDs are also duplicated. This change makes them unique.
A few cosmetic changes are made so that diffing cam0.asl against
cam1.asl has fewer extraneous differences.

RTC BUC control register provides a software interface to
configure the top swap feature. This patch adds implementation
to enable/disable top swap feature and gets it accessible in
romstage as well.
The top swap control functions are exposed only if INTEL_HAS_TOP_SWAP
is selected.
To use the topswap feature a second bootblock has to be added
to the cbfs. Below configs aid in doing that,
INTEL_HAS_TOP_SWAP
INTEL_ADD_TOP_SWAP_BOOTBLOCK
INTEL_TOP_SWAP_BOOTBLOCK_SIZE
Enabling and Disabling topswap, using the added API enables user
to boot alternatively from either bootblock.
