Max Filippov d39af90265 xtensa: add alternative kernel memory layouts ... MMUv3 is able to support low memory bigger than 128MB. Implement 256MB and 512MB KSEG layouts: - add Kconfig selector for KSEG layout; - add KSEG base address, size and alignment definitions to arch/xtensa/include/asm/kmem_layout.h; - use new definitions in TLB initialization; - add build time memory map consistency checks. See Documentation/xtensa/mmu.txt for the details of new memory layouts. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>		2016-07-24 06:33:58 +03:00
