Are you going to submit these > patches at last? Hi Xianwei, I made some progress, and now the SD card controller probes but fails to read blocks from the SD card. I do think my port of the clock driver is okay, but I will not send my clock driver until the SD card fully works, so I am sure the clocking driver is tested. But if you have something already done, please send it, and I will test and review it from my side. Any help with the sdcard controller is also much appreciated.
