* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: (24 commits)
  [Blackfin] arch: import defines for BF547 -- it is just like the BF548, but no CAN
  [Blackfin] arch: fix build fails only include header files when enabled
  [Blackfin] arch: declare default INSTALL_PATH for Blackfin ports
  [Blackfin] arch: Encourage users to use the spidev character driver: Provide platform support
  [Blackfin] arch: Enable UART2 and UART3 for bf548
  [Blackfin] arch: Enable NET2272 on BF561-EZkit - remove request_mem_region
  [Blackfin] arch:Fix BUG [#3876] pfbutton test for BTN3 on bf533 don't show complete info
  [Blackfin] arch: remove duplicated definitions of the line discipline numbers N_* in asm-blackfin/termios.h
  [Blackfin] arch: fix building with mtd uclinux by putting the mtd_phys option into the function it actually gets used in
  [Blackfin] arch: simpler header and update dates
  [Blackfin] arch: move the init sections to the end of memory
  [Blackfin] arch: change the trace buffer control start/stop logic in the exception handlers
  [Blackfin] arch: fix typo in printk message
  [Blackfin] arch: this is an ezkit, not a stamp, so fixup the init function name
  [Blackfin] arch: add slightly better help text for CPLB_INFO
  [Blackfin] arch: Fix BUG - Enable ISP1362 driver to work ok with BF561
  [Blackfin] arch: Fix header file information
  [Blackfin] arch: Add Support for ISP1362
  [Blackfin] arch: add support for cmdline partitioning to the BF533-STAMP flash map driver and enable it as a module by default
  [Blackfin] arch: hook up set_irq_wake in Blackfin's irq code
