[PATCH v2 0/2] ARM: support PHYS_OFFSET minimum aligned at 64KiB boundary

[Zhen Lei]

v1 --> v2:
Nothing changed, but add mail list: patches@xxxxxxxxxxxxxxx

v1:
Currently, only support the kernels where the base of physical memory is
at a 16MiB boundary. Because the add/sub instructions only contains 8bits
unrotated value. But we can use one more "add/sub" instructions to handle
bits 23-16, to support PHYS_OFFSET minimum aligned at 64KiB boundary.

This function is required at least by some Huawei boards, such as Hi1380
board. Becuase the kernel Image is loaded at 2MiB boundary.
