New subject: Change in coreboot[master]: mainboard/amd: Add padmelon board code

3 Jul 2019

Richard Spiegel has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/33993
Change subject: mainboard/amd: Add padmelon board code
......................................................................
mainboard/amd: Add padmelon board code
With almost everything in place, it's time to add padmelon board. There are
2 versions, one using a fanned version of 00670F00 and one using merlinfalcon
(00660F01, also fanned), both SOC FP4 sockets. This code was intended for
merlinfalcon version, but as there are some legal issues (documentation)
blocking its merge to coreboot, it'll be released for 00670F00, being replaced
later with merlinfalcon when the binaries can be merged to coreboot (PSP,
video and AGESA). Even both use fanned versions of SOC, the actual fan control
is done through a SIO, fintek f81803a.
BUG=b:none.
TEST=Both versions tested and boot to Linux using SeaBIOS.
