[ Stephen, I'm only going to CC: on this email not the rest of the patch bomb, as I figured you'd have some at least cursory interest in this work. Thanks. ] A long time ago in a galaxy far far away we had no generic device layer and generic OF device driver infrastructure. Thus I created a bunch of ad-hoc interfaces and datastructures to support SBUS device drivers. Those days are gone but the rotting corpose of the SBUS device layer stays with us. It's time to end that :) This patch series follows roughly the following sequence: 1) Kill ad-hoc SBUS DVMA driver, only ESP and SUNLANCE use this and they can do so with local code. 2) Make dma_map_*() work for SBUS devices. 3) Make SBUS drivers use dma_*() instead of sbus_*(). 4) Convert SBUS drivers to use OF device driver style probing. This is probably the bulk of the patch series. 5) Add local IOMMU controller initialization and a OF node propagator helper routine so that the device->archdata.FOO fields get set on all child devices of a given bus where an IOMMU is discovered setup. 6) rm arch/sparc/include/sbus*.h drivers/sbus/*.c 7) Profit. All of my testing was done on an Ultra2 with ESP, SUNHME, CS4231 audio, and an SBUS Flash device. I plan to do the same for the EBUS bus layer as well. The only tricky case there is the CS4231 sound driver as it supports both EBUS and SBUS devices, but I have a plan to sort that out cleanly. This work will also make converting sparc32 over to the generic IRQ layer much easier as well. Anyways, after this sits for review for a day or two I'll push this into the sparc-next-2.6 tree.
