Thanks. Without this patch, memtest dies early on at physical address
0x05100000 due to an SError. With the patch, things work well, so:

Acked-by: Will Deacon <will.deacon@arm.com>
Tested-by: Will Deacon <will.deacon@arm.com>

Please also CC stable, because random SErrors under load aren't much fun ;)

Cheers,

Will
