This patch series enables thumb compile for tegra SPL and u-boot. It is not ready for review yet as it still contains a few hacks, but I'm posting it in case anyone finds it useful. This reduces the size of the combined SPL/u-boot by about 20%. I havent' measured if there's any change in boot time.
This patch series depends on v6 of the SPL patch series.
This patch series is also available from: git://github.com/arm000/u-boot.git branch: tegra-thumb-v1
