since this also omapl138-based, can't you re-use the board-omapl138-hawk.c board-file ? I mean, this is only initializing console and that's it. What else does this board have ? Does it have USB, that EMAC/MDIO device ? To me it looks like you could re-use that board-file and just add a few machine checks for the different part (??) > -- > 1.7.4.1 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to [email protected] > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ -- balbi
