yes, I figured that too yesterday while testing. > Maybe the qemu_mips specific bootm stuff should be removed completely from > U-Boot? > > -Gabor I agree. Maybe we should convert the current MIPS Qemu port to MTI Malta. I have seen that BareBox already supports Qemu Malta. For supporting real MTI Malta hardware there is AFAIK some work in progress [1].
