  Blackfin arch: Fix PM building on BF52x: No ROTWE on BF52x, add USBWE
  Blackfin arch: sram: use 'unsigned long' for irqflags
  Blackfin arch: let PCI depend on BROKEN
  Blackfin arch: move include/asm-blackfin header files to arch/blackfin
  Blackfin arch: fix bug - MPU crashes under stress
  Blackfin arch: Fix bug - when to rmmod the L1_module, it stucks and then reboot the board.
  Blackfin arch: dont actually need to muck with EMAC_SYSTAT for BF52x for demuxing
  Blackfin arch: Add MTD Partitions for MTD_DATAFLASH, increase max SPI SCLK
