[PATCH v2 04/31] arm64: MMU definitions

* Catalin Marinas [off-list ref] [120814 10:57]:

The virtual memory layout is described in
Documentation/arm64/memory.txt. This patch adds the MMU definitions for
the 4KB and 64KB translation table configurations. The SECTION_SIZE is
2MB with 4KB page and 512MB with 64KB page configuration.

PHYS_OFFSET is calculated at run-time and stored in a variable (no
run-time code patching at this stage).

Care to clarify this part a bit? Is the memory standardized somehow
now and not needed? Or do we still need to add that for various SoCs
later on?

Other than that:
