2014-03-04sh: prefix sh-specific "CCR" and "CCR2" by "SH_"Geert Uytterhoeven
Commit bcf24e1daa94 ("mmc: omap_hsmmc: use the generic config for omap2plus devices"), enabled the build for other platforms for compile testing. sh-allmodconfig now fails with: include/linux/omap-dma.h:171:8: error: expected identifier before numeric constant make[4]: *** [drivers/mmc/host/omap_hsmmc.o] Error 1 This happens because SuperH #defines "CCR", which is one of the enum values in include/linux/omap-dma.h. There's a similar issue with "CCR2" on sh2a. As "CCR" and "CCR2" are too generic names for global #defines, prefix them with "SH_" to fix this.

2012-05-19sh: Tidy up some of the cpu legacy dma header mess.Paul Mundt
This has turned in to quite a mess, and with CPUs that care using dmaengine now it's about time to start cleaning up after the legacy DMA code. For starters, kill off the stubs for the CPUs that don't do anything, as well as all of the unused definitions. This leaves us with a set of IRQs and base addresses we can deal with later.

2010-02-17sh: Fix up more 64-bit pgprot truncation on SH-X2 TLB.Paul Mundt
Both the store queue API and the PMB remapping take unsigned long for their pgprot flags, which cuts off the extended protection bits. In the case of the PMB this isn't really a problem since the cache attribute bits that we care about are all in the lower 32-bits, but we do it just to be safe. The store queue remapping on the other hand depends on the extended prot bits for enabling userspace access to the mappings. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-01-20sh: mach-sdk7786: Probe system FPGA area mapping.Paul Mundt
This implements dynamic probing for the system FPGA. The system reset controller contains a fixed magic read word in order to identify the FPGA. This just utilizes a simple loop that scans across all of the fixed physical areas (area 0 through area 6) to locate the FPGA. The FPGA also contains register information detailing the area mappings and chip select settings for all of the other blocks, so this needs to be done before we can set up anything else.

This paves the way for allowing individual CPUs to overload the individual flushing routines that they care about without having to depend on weak aliases.
