Hello Jason Glenesk, Raul Rangel, Marshall Dawson, Fred Reitberger, Felix Held,

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

to look at the new patch set (#2).

Change subject: soc/amd/common/block/lpc: Add support to not clear port80 enable

soc/amd/common/block/lpc: Add support to not clear port80 enable

SMU locks up sometimes if the port80 enable bit is cleared in the ESPI
Decode register. Add a config to choose between clearing the entire ESPI
Decode Register vs retaining the port80 enable bit.

BUG=None
TEST=Build and boot to OS in Skyrim.
