[coreboot-gerrit] Change in coreboot[master]: pcengines/apu2: implement POSTCAR_STAGE

[Krystian Hebel (Code Review)]

Hello Piotr Król, build bot (Jenkins), Patrick Georgi, Michał Żygowski, Martin Roth,

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

https://review.coreboot.org/c/coreboot/+/32363

to look at the new patch set (#6).

Change subject: pcengines/apu2: implement POSTCAR_STAGE

pcengines/apu2: implement POSTCAR_STAGE

This is done by removing BINARYPI_LEGACY_WRAPPER and adopting the code
to use hooks from state_machine.h.

No post codes are changed, except for those which were explicitly sent in
mainboard/romstage.c. Boot time is reduced by more than 7%, from 5.029s to
4.657s (coreboot timestamps, measured for loglevel 7).

POSTCAR_STAGE will be required starting October 2019.
