I added smc91x support but turns out we currently do not set the smc91x timings in gpmc.c but rely on the bootloader timings. This produces the following error unless the smc91x GPMC timings are initialized by the bootloader: Unhandled fault: external abort on non-linefetch (0x1008) at 0xd080630e ...
