* arm64: Remove non-full-va map codeAlexander Graf2016-03-15-20/+0
| | | | | | | | | | | By now the code to only have a single page table level with 64k page size and 42 bit address space is no longer used by any board in tree, so we can safely remove it. To clean up code, move the layerscape mmu code to the new defines, removing redundant field definitions. Signed-off-by: Alexander Graf <agraf@suse.de>

* armv8: New MMU setup code allowing to use 48+ bits PA/VASergey Temerkhanov2016-01-19-6/+29
| | | | | | | | | | | | | This patch adds code which sets up 2-level page tables on ARM64 thus extending available VA space. CPUs implementing 64k translation granule are able to use direct PA-VA mapping of the whole 48 bit address space. It also adds the ability to reset the SCTRL register at the very beginning of execution to avoid interference from stale mappings set up by early firmware/loaders/etc. Signed-off-by: Sergey Temerkhanov <s.temerkhanov@gmail.com> Signed-off-by: Radha Mohan Chintakuntla <rchintakuntla@cavium.com>
