- * This is a workaround for issues on the MPC5200, where unaligned
- * 32-bit-accesses to the local bus will deliver corrupted data. This
- * happens for example when trying to use memcpy() from an odd NOR
- * flash address; the behaviour can be also seen when using "md" on an
- * odd NOR flash address (but there it is not a bug in U-Boot, which
- * only shows the behaviour of this processor).
- *
- * For memcpy(), we test if either the source or the target address
- * are not 32 bit aligned, and - if so - if the source address is in
- * NOR flash: in this case we perform a byte-wise (slow) then; for
- * aligned operations of non-flash areas we use the optimized (fast)
- * real __memcpy().  This way we minimize the performance impact of
- * this workaround.
