This allows setting the ATAG_REVISION so it gets passed to
the kernel. This is useful for systems that share the same id
but have some small hardware differences between board
revisions.

This patch adds an exec option (-v) to set the board revision

What's it used for? (Why do you need this tag)
I think it would be better in this case to have this provided
automatically. Whatever value you would be passing seems to
be specific to your target, so just define it as a platform
defined value and make the RedBoot exec code pass it.
Define it wherever you've defined HAL_PLATFORM_MACHINE_TYPE, e.g.
#define HAL_PLATFORM_REVISION 123
Then in the code
#if defined(HAL_PLATFORM_REVISION)
...
#endif
Otherwise, you pollute the command with options which do nothing
on most platforms and will just be confusing to users.
