* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: Blackfin SPORTS UART Driver: converting BFIN->BLACKFIN Blackfin serial driver: add extra IRQ flag for 8250 serial driver 8250 Serial Driver: Added support for 8250-class UARTs in HV Sistemas H8606 board Blackfin arch: Fix bug - USB fails to build for BF524/BF526 Blackfin arch: update boards defconfig files Blackfin arch: IO Port functions to read/write unalligned memory Blackfin arch: enable a choice to provide 4M DMA memory Blackfin arch: cleanup the icplb/dcplb multiple hit checks Blackfin arch: Add workaround to read edge triggered GPIOs Blackfin arch: Sync channel defines with struct dma_register dma_io_base_addr. Blackfin arch: Check for Anomaly 05000182 [Blackfin] arch: rename bf5xx-flash to bfin-async-flash [Blackfin] arch: Blackfin checksum annotations
