GCC 4.3.3 and 4.4.1 happily moves the dword load instruction out of the loop in orion_nand_read_buf. This patch makes the instruction volatile to avoid the issue. I've discussed this at gcc-help, refer to the thread at http://gcc.gnu.org/ml/gcc-help/2009-08/msg00187.html The early clobber is added to avoid the destination registers and the source register overlapping.
