Hauke Mehrtens 1a8218d6e4 brcm47xx: add initial support for kernel 3.8
This contains the following new bigger changes:
 * new partition parser which still could lake some features or have bugs
 * new nand flash driver
 * using physmap-flash flash driver for parallel flash
 * some changes to the serial flash driver

With these changes OpenWrt starts using more of the mainline flash drivers.
