When I generate a project for the MPC5643L I get the file __ppc_eabi_init.c
This contains the __flush_cache routine which starts with (cleaned up a bit):
asm void __flush_cache(register void *address, register unsigned int size)
{
. nofralloc
. lis r5, 0xffff
. ori r5, r5, 0xfff1
. and r5, r5, r3 /* make address 8-byte aligned */
. subf r3, r5, r3 /* get unaligned-aligned difference */
. add r4, r4, r3 /* increase size accordingly */
So r5 is loaded with a mask 0xFFFF_FFF1 to make it 8-byte aligned.
Should it not be loaded with 0xFFFF_FFF8 ?
