2009-08-29iop-adma: P+Q support for iop13xx adma enginesDan Williams2-0/+77
iop33x support is not included because that engine is a bit more awkward to handle in that it can either be in xor mode or pq mode. The dmaengine/async_tx layers currently only comprehend static capabilities. Note iop13xx does not support hardware PQ continuation so the driver must handle the DMA_PREP_CONTINUE flag for operations across > 16 sources. From the comment for dma_maxpq: /* When an engine does not support native continuation we need 3 extra * source slots to reuse P and Q with the following coefficients: * 1/ {00} * P : remove P from Q', but use it as a source for P' * 2/ {01} * Q : use Q to continue Q' calculation * 3/ {00} * Q : subtract Q from P' to cancel (2) */ Signed-off-by: Dan Williams <[email protected]>
2009-08-29async_tx: add sum check flagsDan Williams1-2/+3
Replace the flat zero_sum_result with a collection of flags to contain the P (xor) zero-sum result, and the soon to be utilized Q (raid6 reed solomon syndrome) zero-sum result. Use the SUM_CHECK_ namespace instead of DMA_ since these flags will be used on non-dma-zero-sum enabled platforms.

2009-08-18iop3xx: ATU and PCI memory configuration correctedAaro Koskinen1-0/+1
There are two 64 MB outbound memory windows at bus addresses 0x80000000..0x83ffffff and 0x84000000..0x87ffffff for PCI memory. Currently, on iop32x, only the lower window is available for allocations, limiting the available space to 64 MB. On iop33x the full 128 MB can be allocated, but the translation value is wrong for the upper window. The patch enables the full 128 MB space on iop32x and corrects the initialization of OMWTVR1. Redundant definitions are deleted. Tested using a Thecus N2100 board with a graphics adapter in the expansion slot. Both windows are in use: 00:05.0 VGA compatible controller: XGI Technology Inc.

2009-05-30RealView: Add support for the RealView/PBX platformColin Tuckley1-0/+2
This is a RealView platform supporting core tiles with ARM11MPCore, Cortex-A8 or Cortex-A9 (multicore) processors. It has support for MMC, CompactFlash, PCI-E. Signed-off-by: Colin Tuckley <[email protected]> Signed-off-by: Catalin Marinas <[email protected]>

2009-05-18[ARM] S3C64XX: DMA supportBen Dooks1-0/+138
Add support for the DMA blocks in the S3C64XX series of CPUS, which are based on the ARM PL080 PrimeCell system. Unfortunately, these DMA controllers diverge from the PL080 design by adding another DMA controller register and configuration for OneNAND.

2009-05-17[ARM] smp: fix cpumask usage in ARM SMP codeRussell King1-1/+1
The ARM SMP code wasn't properly updated for the cpumask changes, which results in smp_timer_broadcast() broadcasting ticks to non-online CPUs. Signed-off-by: Russell King <[email protected]>
2009-05-07[ARM] VIC: Add power management deviceBen Dooks1-1/+1
Add power management support to the VIC by registering each VIC as a system device to get suspend/resume events going. Since the VIC registeration is done early, we need to record the VICs in a static array which is used to add the system devices later once the initcalls are run. This means there is now a configuration value for the number of VICs in the system. Signed-off-by: Ben Dooks <[email protected]>
2009-03-25[ARM] 5431/1: scoop: completely drop old-style SCOOP GPIO accessorsDmitry Baryshkov1-2/+0

2008-12-15[ARM] VIC: Update asm/hardware/vic.h with PL192 informationBen Dooks1-4/+6
The original arch/arm/include/asm/hardware/vic.h was written for the PL190 ARM VIC implementation, and as such does not have any information about the PL192 version. Add details about the PL192 and PL190 specific registers and any changes between the two units. Signed-off-by: Ben Dooks <[email protected]>
