Merge master.kernel.org:/pub/scm/linux/kernel/git/cooloney/blackfin-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: (30 commits) Blackfin serial driver: supporting BF548-EZKIT serial port Video Console: Blackfin doesnt support VGA console Blackfin arch: Add peripheral io API to gpio header file Blackfin arch: set up gpio interrupt IRQ_PJ9 for BF54x ATAPI PATA driver Blackfin arch: add missing CONFIG_LARGE_ALLOCS when upstream merging Blackfin arch: as pointed out by Robert P. J. Day, update the CPU_FREQ name to match current Kconfig Blackfin arch: extract the entry point from the linked kernel Blackfin arch: clean up some coding style issues Blackfin arch: combine the common code of free_initrd_mem and free_initmem Blackfin arch: Add Support for Peripheral PortMux and resouce allocation Blackfin arch: use PAGE_SIZE when doing aligns rather than hardcoded values Blackfin arch: fix bug set dma_address properly in dma_map_sg Blackfin arch: Disable CACHELINE_ALIGNED_L1 for BF54x by default Blackfin arch: Port the dm9000 driver to Blackfin by using the correct low-level io routines Blackfin arch: There is no CDPRIO Bit in the EBIU_AMGCTL Register of BF54x arch Blackfin arch: scrub dead code Blackfin arch: Fix Warning add some defines in BF54x header file Blackfin arch: add BF54x missing GPIO access functions Blackfin arch: Some memory and code optimizations - Fix SYS_IRQS Blackfin arch: Enable BF54x PIN/GPIO interrupts ...
