Add support for AMCC Sequoia PPC440EPx eval board
- Add support for PPC440EPx & PPC440GRx - Add support for PPC440EP(x)/GR(x) NAND controller in cpu/ppc4xx directory - Add NAND boot functionality for Sequoia board, please see doc/README.nand-boot-ppc440 for details - This Sequoia NAND image doesn't support environment in NAND for now. This will be added in a short while. Patch by Stefan Roese, 07 Sep 2006
