I have a patch for this in my Linux tree too so I sent that: https://lore.kernel.org/lkml/[email protected]/T/#mab66837bb90c30916fd0fc066245bdeb9918e96c It would seem our versions of readl(), writel() etc are broken. For Linux the nommu versions are broken, for u-boot it seems they are all broken. By broken I mean they should be expecting a little endian value from the access and then converting to the CPU endian. (I think) Cheers, Daniel
