That's useful to know. The PL180 code is also used for U8500, I don't know if that implements the peripheral ID register; though I guess any probing could be limited to vexpress anyway. However, I think that if smaller and simpler code will work on all hardware then that is preferable. -- Tixy _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
