Merge remote-tracking branch 'u-boot/master'

Conflicts:
	boards.cfg

Conflicts were trivial once u-boot-arm/master boards.cfg was
reformatted (commit 6130c146) to match u-boot/master's own
reformatting (commit 1b37fa83).

+Sandbox Environment:
+--------------------
+
+U-Boot can be built natively to run on a Linux host using the 'sandbox'
+board. This allows feature development which is not board- or architecture-
+specific to be undertaken on a native platform. The sandbox is also used to
+run some of U-Boot's tests.

+See board/sandbox/sandbox/README.sandbox for more details.
