[U-Boot] [PATCH 00/26] dm: tegra: Move nyan-big to livetree

[Simon Glass]

This moves an entire board to use a live device tree as an example of the
impact.

Nyan-big was chosen because I can easily and boot U-Boot without any
media swapping, etc.

Total code size impact on this board is approximately 9KB on U-Boot and
64 bytes on SPL:

27: dm: tegra: nyan-big: Move to livetree
       arm: (for 1/1 boards) all +9264.0 bss -16.0 data +44.0 rodata +92.0
          spl/u-boot-spl:all +326.0 spl/u-boot-spl:rodata +262.0
          spl/u-boot-spl:text +64.0 text +9144.0

Tegra does not use Thumb2, which would likely reduce the code size by about
25%, indicating a code-size impact of perhaps 7KB.

I have not yet collected reliable detailed timing information. I will do
that with the next version of this series, after comments are received.
I expect that building the live tree will take a little time, and that
using it will be very slightly faster.

The use of livetree is controlled by a the CONFIG_OF_LIVE option. When
enabled, U-Boot builds a livetree immediately after relocation and uses
it from then on.

This series is available at u-boot-dm/livet-working

(note that some work remains for apalis-tk1, jetson-tk1, cei-tk1-som)
