* powerpc/8xxx: Add additional cycle to write-to-read turnaound for DDR3York Sun2011-02-101-1/+1
| | | | | | | | | When DDR data rate is higher than 1200MT/s or controller interleaving is enabled, additional cycle for write-to-read turnaround is needed to satisfy dynamic ODT timing. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Move arch/ppc to arch/powerpcStefan Roese2010-04-211-0/+81
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
