* BCM2708 defines no longer assume 0x20 address We will be throwing away the blob memory mapping and using our own. * Use existing blob mapping to turn GPIO led on pre mmu_init * Remap MMU hardware addresses from 0x7E. We could map each device, however the kernel will throw away the mappings again anyway. For now we just map the whole range and use offsets. * Serial uart no longer works, however at least we know why now :). Serial driver now needs to use mapped address.
