I'm no Linux expert but "ERROR: could not get clock /sopc@0/dma@0xffda1000:apb_pclk(0)" doesn't look good. If DMA isn't working you won't be reading anything from your SD card. I'm not saying this is the case, but it's worth getting a Linux expert to take a look.

I assume your preloader and uboot are both on the SD card. This means the basic SD hardware is working. I think that neither preloader nor uboot use DMA, so the first use of DMA is in the Linux kernel.
