[coreboot-gerrit] Change in coreboot[master]: mb/google/dedede: Add a board specific reset

[Karthik Ramasubramanian (Code Review)]

Hello build bot (Jenkins), Furquan Shaikh, Justin TerAvest, Tim Wawrzynczak, Marco Chen,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/44189

to look at the new patch set (#5).

Change subject: mb/google/dedede: Add a board specific reset

mb/google/dedede: Add a board specific reset

When CSE Lite jumps from RO to RW, global reset is initiated. When AP is
reset as part of global reset, TPM initialization fails. This is because
AP reset is not detected by TPM hosting an older firmware version. Request
Embedded Controller (EC) to perform AP reset so that TPM can detect that
event.

BUG=b:162290856, b:162386991
TEST=Ensure that the device boots to OS with the board-specific reset
sequence when CSE Lite jumps from RO to RW with an older and newer Cr50
firmware.
