ARM: davinci: sram: switch from iotable to ioremapped regions
The current davinci init sets up SRAM in iotables. There has been an observed failure to boot a da850 with 128K specified in the iotable. Make the davinci sram allocator do an ioremap of the region specified by the entries in davinci_soc_info before registering with gen_pool_add_virt(). Remove all iotable SRAM mappings and SRAM_VIRT. Regression tested suspend/resume on AM180x EVM. Signed-off-by: Ben Gardiner <bengardiner@nanometrics.ca> Signed-off-by: Matt Porter <mporter@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
