ppc4xx: Generic architecture for xilinx ppc405

As "ppc44x: Unification of virtex5 pp440 boards" did for the xilinx ppc440 boards, this patch presents a common architecture for all the xilinx ppc405 boards.

Any custom xilinx ppc405 board can be added very easily with no code duplicity.

This patch also adds a simple generic board, that can be used on almost any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h

This patch is prepared to work with the latest version of EDK (10.1)

Please patch it against ppc4xx/next

As "ppc44x: Unification of virtex5 pp440 boards" did for the xilinx ppc440 boards, this patch presents a common architecture for all the xilinx ppc405 boards.

Any custom xilinx ppc405 board can be added very easily with no code duplicity.

This patch also adds a simple generic board, that can be used on almost any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h

This patch is prepared to work with the latest version of EDK (10.1)

Signed-off-by Ricardo Ribalda Delgado <[email protected]>

How about the existing Xilinx PPC405 boards like ml300? Should they somehow use this new infrastructure?
