This patch adds generic board, start of day and basic build system
support for
the Allwinner A20 (sun7i) processor. This code will not been compiled
until the
build is hooked up in a later patch. It has been split out to keep
the patches
manageable.

v4: Based on d9fe0a1e061e "sunxi: mksunxiboot: remove unnecessary
casts."
v3: Based on c89867dca2e9 "sunxi: clocks: clock_get_pll5
prototype and coding style".
v2: Based on u-boot-sunxi.git#sunxi d9aa5dd3d15c "sunxi: mmc:
checkpatch whitespace fixes" with v2014.04-rc2 merged in:
- just init dram once
- remove clock ramping until power control is implemented
- add CONFIG_SUN7I to simplify future SUN?I support.
- fix a typo
v1: Based on u-boot-sunxi.git#sunxi commit d854c4de2f57 "arm: Handle
.gnu.hash
section in ldscripts" vs v2014.01.

Can we please fix these last two values which are obviously wrong (at
least on sun7i, they point to the SRAM controller address, as shown in
the documentation on page 18).
I've been carrying a patch for this in my tree:
http://git.kernel.org/cgit/linux/kernel/git/maz/u-boot.git/commit/?h=wip/psci-v4-a20&id=e8cea4226fdbf7718f0b888b32f24d2803b168c6
Can you squash it into your next version?
Thanks,
M.
