Vineet Gupta deaf7565eb ARCv2: ioremap: Support dynamic peripheral address space ... The peripheral address space is architectural address window which is uncached and typically used to wire up peripherals. For ARC700 cores (ARCompact ISA based) this was fixed to 1GB region 0xC000_0000 - 0xFFFF_FFFF. For ARCv2 based HS38 cores the start address is flexible and can be 0xC, 0xD, 0xE, 0xF 000_000 by programming AUX_NON_VOLATILE_LIMIT reg (typically done in bootloader) Further in cas of PAE, the physical address can extend beyond 4GB so need to confine this check, otherwise all pages beyond 4GB will be treated as uncached Signed-off-by: Vineet Gupta <vgupta@synopsys.com>		2016-03-19 14:34:10 +05:30
