Subject: [PATCH v3 00/10] Rework current Tegra support

Round 3 of the Tegra rework. A bit beefier this time, as I folded in
some real advancements. Most notable a working GPIO driver and
the 1st stage loading support. Barebox is now aware of the CPU it's
running on and boots the Tegra main CPU cluster if needed. Don't get
too exited yet, you most likely won't see anything when running first
stage, as the pinmux stays in reset state and there is no driver to
switch it to the state needed for your board. 2nd stage loading
should work as before from the same binary.

I've also converted Tegra to builtin DTB, as I would like to
follow the kernel and go a DT only way. Let's see how this works out,
but as U-Boot isn't far away from defining Tegra boards only through
the DT I'm almost sure we can make it work in barebox.

A note for the review: I won't split patches just for the sake of
it. I'm actively working on this code as long as it isn't pulled into
the basebox repo and it's already hard enough to keep track of which
hunks of code should go into the individual patches.

Antony: I've converted the serial and ramsize detection to the
standard used in U-Boot and Linux. Please test if this works for
your board. If not it's not really a barebox error, as your ODMdata
is most likely wrong in this case, but please let me know anyway as
I would like to avoid breaking existing boards.

Lucas Stach (10):
  tegra: pull in iomap.h from the Linux kernel
  tegra: define TEGRA20 arch type
  tegra: switch to DT only
  tegra: add driver for the clock and reset module
  tegra: add T20 timer driver
  tegra: add T20 power management controller driver
  tegra: add common lowlevel startup
  tegra: add generic debug UART support
  tegra: add generic meminit
  tegra: add GPIO controller driver
