2008-10-03[ARM] 5278/1: i2c-pxa fast mode supportJonathan Cameron
Add fast_mode option to i2c_pxa_platform_data and use it to set the ICR_FM bit appropriately when i2c_pxa_reset is called. Parameter called fast_mode rather than frequency as this driver is also used for the i2c_pxa_pwr bus which has different normal and fast frequencies.

2008-10-03[ARM] 5229/3: Replace some ARMv7 opcodes with the instruction nameCatalin Marinas
These instructions were placed in the code directly as opcodes because early compilers didn't support them. Toolchains supporting ARMv7 understand these instructions and the patch puts the mnemonics back.

2008-10-03[ARM] 5276/1: ep93xx: allow selecting UART for early kernel messagesHartley Sweeten
Currently on the EP93xx platform early kernel messages go to UART1. Since this UART is the only one that has modem control signals it might be used for another purpose and it is undesirable for those messages to appear. This patch allows one of the other UARTs to be selected in the kernel configuration. It is assumed that the bootloader has configured and initialized the UART since this was the previous assumption.

2008-10-02[ARM] 5274/1: simplify request_standard_resources()Nicolas Pitre
There is no point converting memory bank addresses from physical to virtual just to convert them back to physical addresses.

2008-10-01[ARM] Remove MT_DEVICE_IXP2000 and associated definitionsRussell King
As of the previous commit, MT_DEVICE_IXP2000 encodes to the same PTE bit encoding as MT_DEVICE, so it's now redundant. Convert MT_DEVICE_IXP2000 to use MT_DEVICE instead, and remove its aliases. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-10-01[ARM] Introduce new PTE memory type bitsRussell King
Provide L_PTE_MT_xxx definitions to describe the memory types that we use in Linux/ARM. These definitions are carefully picked such that: 1. their LSBs match what is required for pre-ARMv6 CPUs. 2. they all have a unique encoding, including after modification by build_mem_type_table() (the result being that some have more than one combination.)

2008-09-30[ARM] mm: move vmalloc= parsing to arch/arm/mm/mmu.cRussell King
There's no point scattering this around the tree, the parsing of the parameter might as well live beside the code which uses it. That also means we can make vmalloc_reserve a static variable. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-09-30[ARM] mm: move validation of membanks to one placeRussell King

2008-09-30[ARM] dma: don't touch cache on dma_*_for_cpu()Russell King
As per the dma_unmap_* calls, we don't touch the cache when a DMA buffer transitions from device to CPU ownership. Presently, no problems have been identified with speculative cache prefetching which in itself is a new feature in later architectures. We may have to revisit the DMA API later for these architectures anyway. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-09-29[ARM] dma: fix dmabounce dma_sync_xxx() implementationsRussell King
The dmabounce dma_sync_xxx() implementation have been broken for quite some time; they all copy data between the DMA buffer and the CPU visible buffer no irrespective of the change of ownership. (IOW, a DMA_FROM_DEVICE mapping copies data from the DMA buffer to the CPU buffer during a call to dma_sync_single_for_device().) Fix it by getting rid of sync_single(), moving the contents into the recently created dmabounce_sync_for_xxx() functions and adjusting appropriately. This also makes it possible to properly support the DMA range sync functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
