[PATCH ARM v7 00/13] mini-os: initial ARM support

[Thomas Leonard <talex5@gmail.com>]

This series is based on Karim's ARM support commits, further broken up into
smaller patches.

Changes since v6:

- Added missing includes in stubdom code.
- Move poor rand function to test.c.
- Fixed printk format types.
- Only build libfdt with read support, since that's all we need.
- Compiling with debug=n now works.

Addressed Andrew Cooper's comment:
- Use Xen's existing copy of libfdt instead of including our own copy.

Addressed Ian Campbell's comments:
- ARMv7 A8.8.247 says udf should not be used conditionally, so use
  a branch instead.
- Enable caching earlier (required setting the cacheability for the
  translation table walks).
- Added some extra dsb instructions to protect against reordering.
- Replace "mov pc" with "bx".
- Preserve all callee-saved registers on thread switch.

Addressed Julien Grall's comments:
- Note that TTBCR is zero (using short-descriptors, TTBR0 only).
- Note about relying on 0x8000 load offset.
- Remove wall-clock time support (doesn't work on ARM anyway).
- Converted an ?: to an if.
- paddr_t is now uint64_t.
