Looks okay to me, some minor comments below:

I was playing around before and my test scripts noticed checkpatch
complained about the spacing with the array indexing: "[PALMETTO_BMC]"
fixed the error.

I feel like we should pass a "struct AspeedBoardConfig *" rather than
the "int board_model", cleaning up the repeated indexing into
aspeed_boards the body. Thoughts? </bikeshed>
