* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: (60 commits)
  Blackfin arch: make sure we include the fix for SPORT hysteresis when reprogramming clocks
  Blackfin arch: Fix bogus str_ident check in gpio code
  Blackfin arch: AD7879 Touchscreen driver
  Blackfin arch: introducing bfin_addr_dcachable
  Blackfin arch: fix a typo in comments
  Blackfin arch: Remove useless head file
  Blackfin arch: make sure L2 start and length are always defined (fixes building on BF542)
  Blackfin arch: use the Blackfin on-chip ROM to do software reset when possible
  Blackfin arch: update anomaly headers to match the latest sheet
  Blackfin arch: bfin_reset() is an internal reboot function ... everyone should go through machine_restart()
  Blackfin arch: print out error/warning if you are running on the incorrect CPU type
  Blackfin arch: remove non-bf54x ifdef logic since this file is only compiled on bf54x parts
  Blackfin arch: update board defconfigs
  Blackfin arch: Add optional verbose debug
  Blackfin arch: emulate a TTY over the EMUDAT/JTAG interface
  Blackfin arch: have is_user_addr_valid() check for overflows (like when address is -1)
  Blackfin arch: ptrace - fix off-by-one check on end of memory regions
  Blackfin arch: Enable framebuffer support for the BF526-EZkit TFT LCD display
  Blackfin arch: flash memory map and dm9000 resources updating
  Blackfin arch: early prink code still use uart core console functions to parse and set configure option string
