ppc4xx: Initial framework of the AMCC PPC460SX redwood reference board. Add AMCC Redwood reference board that uses the latest PPC 464 CPU processor combined with a rich mix of peripheral controllers. The board will support PCIe, mutiple Gig ethernet ports, advanced hardware RAID assistance and IEEE 1588. Signed-off-by: Feng Kan <fkan@amcc.com> Signed-off-by: Stefan Roese <sr@denx.de>

Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>" The appropriate include/asm-$ARCH directory should already by symlinked to include/asm so using the whole "asm-$ARCH" path is unnecessary. This change should also allow us to move the include/asm-$ARCH directories into their appropriate lib/$ARCH/ directories. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

ppc4xx: Use common NS16550 driver for PPC4xx UART This patch removes the PPC4xx UART driver. Instead the common NS16550 driver is used, since all PPC4xx SoC's use this peripheral device. The file 4xx_uart.c now only implements the UART clock calculation function which also sets the SoC internal UART divisors. All PPC4xx board config headers are changed to use this common NS16550 driver now. Tested on these boards: acadia, canyonlands, katmai, kilauea, sequoia, zeus Signed-off-by: Stefan Roese <sr@denx.de>

ppc4xx: TLB init file cleanup This patch adds new macros, with frequently used combinations of the 4xx TLB access control and storage attibutes. Additionally the 4xx init.S files are updated to make use of these new macros. Resulting in easier to read TLB definitions. Additionally some init.S files are updated to use the mmu header for the TLB defines, instead of defining their own macros. Signed-off-by: Stefan Roese <sr@denx.de>
