From: Brian Swetland Date: Wed, 10 Sep 2008 21:00:53 +0000 (-0700) Subject: [ARM] msm: clean up iomap and devices X-Git-Tag: firefly_0821_release~17115^2~5^2~3 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=bcc0f6af0798e60e7527485f7125ed26632ce698;p=firefly-linux-kernel-4.4.55.git [ARM] msm: clean up iomap and devices - Add some more peripherals (sdcc, etc) to the iomap. - Remove virtual base addresses for devices that we should be passing physical addresses to drivers via resources and ioremap()ing. - don't try to use uarts for ll debug once the mmu is enabled due to problems with the peripheral window - make base addresses void __iomem * and fixup irq.c and timer.c - Remove common.c and bring in devices.c/devices.h similar to the PXA architecture.
