2012-09-13ARM: msm: Fix early debug uart mapping on some memory configsStephen Boyd
The uart mapping runs into the space allocated for lowmem on some 8960 boards when we have more than 512Mb of memory. We were getting lucky before and our mapping wasn't part of DDR. Move the mapping up into the vmalloc area which will always be outside of the lowmem mapping regardless of how much lowmem actually exists.

2012-09-13ARM: msm: Remove unused idle.cStephen Boyd
Forcing arm_pm_idle to be msm_idle() doesn't make sense in configurations that don't have CONFIG_MSM7X00A_IDLE=y (i.e. any targets that aren't 7x00a). Furthermore, that config doesn't even exist, so this entire file is dead code. Just remove it so we can use the default idle support on MSM.

2012-09-13ARM: msm: io: Change the default static iomappings to be sharedRohit Vaswani
With 3.4 kernel the static iomappings can be shared with the ioremap mappings. If ioremap is called with an address for which a static mapping already exists, then that mapping should be used instead of creating a new one. However, the MT_DEVICE_NONSHARED flag prevents this. Hence, get rid of this flag. Some targets (7X00) that require the static iomappings to be NONSHARED use the MSM_DEVICE_TYPE and MSM_CHIP_DEVICE_TYPE macros.

2012-09-13ARM: msm: Remove call to missing FPGA init on 8660David Brown
A previous patch[1] added code to initialize an FPGA register on the 8660 "SURF" development platform. Since this development platform is not widely available, and there is now a more available device "the Dragonboard" based on the same core SOC, this change was dropped. However, the DT code kept a lingering call to this FPGA init function. Remove it. [1] https://lkml.org/lkml/2011/8/12/357 Signed-off-by: David Brown <davidb@codeaurora.org>
