[U-Boot] [PATCH 0/4 v2]: ARM: vexpress: add support for more core tiles

[Andre Przywara]

This series adds support for the Cortex-A5 and Cortex-A15 core tiles
for the ARM Versatile Express boards.

The first two patches have been around for about one and a half
years in the Linaro tree now, they refactor the A9 support and add
support for A5. I kept the original commits and authors, just
resolved some trivial merge conflicts and checkpatch complaints.
As per request, I merged the first two original patches into one
for better readability.

Patch 3/4 adds support for the A15 core tile, this is actually the
same as the A5 for now, but will be extended later.

Patch 4/4 enables bootz and hush parser for all boards, just for
convenience.

Changes:
v2:
  - merge patch 1/5 and 2/5 as per Albert's request
  - add support for raw initrd for full bootz experience

Regards,
Andre.
