I suppose he is trying 64bit kernel on RBTX4938 board, but the board
dependent code seems not ready for 64bit.  For example, there are some
0xff1fXXXX constants there and all these constants must be sign
extended (0xffffffffff1fXXXX) for 64bit.  Also these virtual address
are mapped to 36bit physical address 0xfff1fXXXX so some assumption in
the 32bit kernel (virt==phys for TX49 internal regs) is not true in
64bit kernel.
