2010-02-15omap2/3: Update omap3_defconfig to build in all the 2420 based boardsTony Lindgren
Note that booting 2420 depends on another patch posted earlier to not select CONFIG_CPU_32v6K if CONFIG_ARCH_OMAP2 is selected. Also note that we cannot add omap2430 in yet because of the different clock addresses compared to 2420. Also note that we cannot have CONFIG_CPU_32v6K=y in order to boot on 24xx.

2010-02-15omap2/3: Make get_irqnr_and_base common for mach-omap2 multibootTony Lindgren
Make get_irqnr_and_base common for mach-omap2 multiboot Thanks to a tip from Russell King <rmk+kernel@arm.linux.org.uk>, this also optimizes the code for non-multiboot configurations by using get_irqnr_preamble. Note that this will only work currently for 24xx and 34xx. Support for 44xx can be added later on for basic multiboot, and similar patch should be done for mach-omap1/entry-macro.S.

2010-02-15omap: Make uncompress code and DEBUG_LL code genericTony Lindgren

2010-02-15omap: Clean the serial port definesTony Lindgren
This way we don't have conflicts with the defines with compiling in multiple omaps. Set the addresses for uarts in struct omap_globals for the early serial init code. Signed-off-by: Tony Lindgren <tony@atomide.com>
2010-02-15arm/mx2: define seperate imx_nand devices for imx21 and imx27Uwe Kleine-König
As the NFC controller has different addresses on imx21 and imx27 there are two different devices needed if not relying on the overloaded cpp macro NFC_BASE_ADDR. So some cpp magic is added to minimize code duplication. As obviously these two defines need different names, the name of the old device is #defined to the new one when building for only one of imx21 or imx27.

2010-02-15ARM: dma-mapping: fix for speculative prefetchingRussell King
ARMv6 and ARMv7 CPUs can perform speculative prefetching, which makes DMA cache coherency handling slightly more interesting. Rather than being able to rely upon the CPU not accessing the DMA buffer until DMA has completed, we now must expect that the cache could be loaded with possibly stale data from the DMA buffer. Where DMA involves data being transferred to the device, we clean the cache before handing it over for DMA, otherwise we invalidate the buffer to get rid of potential writebacks. On DMA Completion, if data was transferred from the device, we invalidate the buffer to get rid of any stale speculative prefetches.

2010-02-14ARM: 5935/1: [U300] Fix the DMA configurationLinus Walleij
This fixes a few bugs in the DMA configuration for the COH 901 318 DMA engine used in U300. It also removes the directional parameter for each channel: separate DMA engine patches (submitted to the DMA engine maintainer) switches that mechanism over to using dynamic configuration of this, to handle bidirectional DMA channels.
