Dear Christophe,
my MPC5200-based system stopped booting recently. I bisected the problem
to your commit below. If I revert that commit (on top of
807249d3ada1ff28a47c4054ca4edd479421b671 = v4.2-6663-g807249d), my
system boots again.
Do you use mainline code only, or do you have home-made code ?
memcpy() is not supposed to be used on non-cacheable memory.
memcpy_toio() is the function to use when copying to non-cacheble area.
When I submitted the patch, I looked for erroneous use of memcpy() and
memset().
I found one wrong use of memset() that I changed to memset_io() but I
didn't find any misuse of memcpy().
But I may have missed one.
Christophe
