Minimal device tree for CMM bmc board to boot into a console over UART with some drivers functional.
Signed-off-by: Matthew Conolly <mattconolly@fb.com>
---
I'm going to start looking at the UART1 pinctl that Andrew mentioned
v3:
Changed fmc compatible string to use "aspeed,ast2400-fmc" as per review
v2:
Rebased patch on the openbmc github dev-4.7 branch
Removed commented out eeprom
Removed of_machine_is_compatible for LPC/UART config
checkpatch whitespace fixup
