  memory: tegra: Explicitly mark defines unsigned (2015-04-03 00:01:09 +0200)

This is essentially the same as the earlier pull requests, except that
it contains fixes for the linux-next build errors reported by Mark
Brown.

Thanks,
Thierry

ARM: tegra: Core code changes for v4.1-rc1

The biggest chunk of these changes is Mikko and Tomeu's external memory
controller driver. It allows the frequency of the external memory to be
changed and also puts the initial pieces into place to enable automatic
scaling of the EMC frequency.

There are also a couple of improvements such as the move to a restart
handler to make it easier for boards to override restart behaviour in a
board-specific way. There are also some preparatory patches to enable
Tegra to run in big-endian mode.

Finally there's a fix for a regression that was introduced in v3.17,
causing suspend/resume to break.
