Hello build bot (Jenkins), Jason Glenesk, Raul Rangel, Marshall Dawson, Matt DeVillier, Fred Reitberger, Felix Held,

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

to look at the new patch set (#28).

Change subject: soc/amd/common/psp: Support PSP SMI handler
......................................................................

soc/amd/common/psp: Support PSP SMI handler

Enable optional support for registering an SMI handler for PSP
SPI flash read/write/erase operation requests.

The PSP SMI needs to be configured before the PSP can actually
issue SMI after being informed of the SMI trigger info via the
SMM_INFO command.

See AMD document 55570 revision 3.16 for additional details.

The PSP will not trigger SMI until informed via the SMM area
buffer that SMM requests are ready to be served.

See AMD document 55758 revision 2.00 for additional details.
