[U-Boot] [PATCH v2 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.

Allen Martin (9):
  tools, config.mk: add binutils-version
  arm: work around assembler bug
  tegra20: remove inline assembly for u32 cast
  arm: add _thumb1_case_uqi to libgcc
  arm: use thumb compatible return in arm720t
  arm: change arm720t to armv4t
  arm720t: add linkage macro for relocate_code
  arm: use thumb interworking returns in libgcc
  tegra20: enable thumb build
