[U-Boot] [PATCH v3 0/9] enable thumb for tegra20

[Allen Martin]

Add changes necessary to enable thumb compilation for tegra20.  This
series includes two patches to work around a bug in gas that
incorrectly optimizes short jumps in thumb mode that were posted
separately.  They can be dropped from this series when they are applied.
