Patrick Georgi submitted this change.
mainboard/amd: Add padmelon board code
Padmelon board code was written for Merlin Falcon (family 15h models 60h-6fh),
but as the needed binaries are not yet merged (commit 33615), a config
HAVE_MERLINFALCON_BINARIES was added. If the binaries are not available,
the board defaults to Prairie Falcon, which use the same binaries as Stoney
Ridge. Once the binaries are merged, the config will be eliminated. Fan
control is done through F81803A SIO, and IRQ/GPIO and other board
characteristics are the same regardless of Merlin Falcon or Prairie Falcon.
Padmelon board was created to accept Prairie Falcon, Brown Falcon and Merlin
Falcon. The requested development was for Merlin Falcon. There are some small
spec changes (such as number of memory channels) between SOCs. Brown Falcon
was not investigated, Prairie Falcon is very similar to Stoney Ridge.
Started from Gardenia code, added changes created by Marc Jones and finally
revised against schematic, which added changes to GPIO settings.
BUG=none.
TEST=Both versions tested and boot to Linux using SeaBIOS.
