I have a bunch of sc520 fixes from a board port I did. This one is cause
by a bad linker directive file (u-boot.lds).
I believe I fixed the other sc520's also. I need to check and submit a
patch.
My board has a 512k 8-bit flash - you will have to adjust the flash
address in the linker file and in the 16 bit .S if your flash is larger.
