ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.h Based on earlier discussions[1] we attempted to find a suitable location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP: DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion to dmaengine is complete. Unfortunately that was before I was able to try to test compile of the ARM multiplatform builds for omap2+, and the end result was not very good. So I'm creating yet another all over the place patch to cut the last dependency for building omap2+ for ARM multiplatform. After this, we have finally removed the driver dependencies to the arch/arm code, except for few drivers that are being worked on. The other option was to make the <plat-omap/dma-omap.h> path to work, but we'd have to add some new header directory to for multiplatform builds. Or we would have to manually include arch/arm/plat-omap/include again from arch/arm/Makefile for omap2+. Neither of these alternatives sound appealing as they will likely lead addition of various other headers exposed to the drivers, which we want to avoid for the multiplatform kernels. Since we already have a minimal include/linux/omap-dma.h, let's just use that instead and add a note to it to not use the custom omap DMA functions any longer where possible. Note that converting omap DMA to dmaengine depends on dmaengine supporting automatically incrementing the FIFO address at the device end, and converting all the remaining legacy drivers. So it's going to be few more merge windows.

ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+ As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.

ARM: OMAP: clocks: Delay clk inits atleast until slab is initialized clk inits on OMAP happen quite early, even before slab is available. The dependency comes from the fact that the timer init code starts to use clocks and hwmod and we need clocks to be initialized by then. There are various problems doing clk inits this early, one is, not being able to do dynamic clk registrations and hence the dependency on clk-private.h. The other is, inability to debug early kernel crashes without enabling DEBUG_LL and earlyprintk. Doing early clk init also exposed another instance of a kernel panic due to a BUG() when CONFIG_DEBUG_SLAB is enabled.

So move them to a point just before the timer code starts using clocks and hwmod. This should at least pave way for clk inits on OMAP moving to dynamic clock registrations instead of using the static macros defined in clk-private.h. The issue with kernel panic while CONFIG_DEBUG_SLAB is enabled was reported by Piotr Haber and Tony Lindgren and this patch fixes the reported issue as well.

ARM: OMAP4: Fix errata i688 with MPU interconnect barriers. On OMAP4 SOC, intecronnects has many write buffers in the async bridges and they need to be drained before CPU enters into standby state. Patch 'OMAP4: PM: Add CPUX OFF mode support' added CPU PM support but OMAP errata i688 (Async Bridge Corruption) needs to be taken care to avoid issues like system freeze, CPU deadlocks, random crashes with register accesses, synchronisation loss on initiators operating on both interconnect port simultaneously. As per the errata, if a data is stalled inside asynchronous bridge because of back pressure, it may be accepted multiple times, creating pointer misalignment that will corrupt next transfers on that data path until next reset of the system (No recovery procedure once the issue is hit, the path remains consistently broken). Async bridge can be found on path between MPU to EMIF and MPU to L3 interconnect. This situation can happen only when the idle is initiated by a Master Request Disconnection (which is trigged by software when executing WFI on CPU). The work-around for this errata needs all the initiators connected through async bridge must ensure that data path is properly drained before issuing WFI. This condition will be met if one Strongly ordered access is performed to the target right before executing the WFI. In MPU case, L3 T2ASYNC FIFO and DDR T2ASYNC FIFO needs to be drained. IO barrier ensure that there is no synchronisation loss on initiators operating on both interconnect port simultaneously. Thanks to Russell for a tip to conver assembly function to C fuction there by reducing 40 odd lines of code from the patch.
