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)
