The 601 processor will generate an alignment exception for accesses which cross a page boundary. In the boot wrapper code, OF is still handling all exceptions, and it doesn't have an alignment exception handler that emulates the instruction and continues. This changes the memcpy and memmove routines in the boot wrapper to avoid doing unaligned accesses. If the source and destination are misaligned with respect to each other, we just copy one byte at a time. Signed-off-by: Paul Mackerras <paulus@samba.org> |
