The PL330 driver probes the peripheral and primecell IDs of the device to make sure that it is indeed an AMBA PL330. However, it does this by making byte accesses to a device mapping of the word-aligned ID registers, which is either UNPREDICTABLE or generates an alignment fault (depending on the presence of the virtualisation extensions). Rather than fix this code, we can actually rip most of it out and let the AMBA bus driver correctly do the probing for us.

2013-07-04Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linuxLinus Torvalds8-25/+19
Pull device tree updates from Grant Likely: "This branch contains the following changes: - Removal of CONFIG_OF_DEVICE, it is always enabled by CONFIG_OF - Remove #ifdef from linux/of_platform.h to increase compiler syntax coverage - Bug fix for address decoding on Bimini and js2x powerpc platforms. - miscellaneous binding changes One note on the above. The binding changes going in from all kinds of different trees has gotten rather out of hand. I picked up some during this cycle, but even going though my tree isn't a great fit. Ian Campbell has prototyped splitting the bindings and .dtb files into a separate repository. The plan is to migrate to using that sometime in the next few kernel releases which should get rid of a lot of the churn on binding docs and .dts files" * tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux: of: Fix address decoding on Bimini and js2x machines of: remove CONFIG_OF_DEVICE usb: chipidea: depend on CONFIG_OF instead of CONFIG_OF_DEVICE of: remove of_platform_driver ibmebus: convert of_platform_driver to platform_driver driver core: move to_platform_driver to platform_device.h mfd: DT bindings for the palmas family MFD ARM: dts: omap3-devkit8000: fix NAND memory binding of/base: fix typos of: remove #ifdef from linux/of_platform.h
