It looks like arch/arm/cpu/armv7/tegra2/board.h and
arch/arm/cpu/armv7/tegra2/uart.c are added in the first patch, then
moved in this patch.  It'd be ideal to just add them once in the proper
location.

On a side note, if you pass "git format-patch" the -M and -C options it
will make pretty diffs that only show what lines changed during a move.
In the case that you do move files in the future its nice to use those
options to ease review.

How about:
#if defined(CONFIG_TEGRA2_ENABLE_UARTA) || defined(CONFIG_TEGRA2_ENABLE_UARTD)
	init_uart();
#endif

Best,
