Aren't we going to need it for other CPUs ? I've a similar patch for DMA, but if I change only BCM2835_ARM_IO_BASE, while it seems to work (sdhci attach fine and it can complete the transfers) the data is just garbage, you can't actually use the SD card, have you tried to verify the data read with this patch ? Thanks for your work, it is much appreciated. Regards, Luiz
