The latest -rc version, or Linus git tree. During the development work,
don't stay on a fixed version: keep your patches updated until you
submit them for inclusion. For more details, ask on the
linux-arm-kernel mailing list
(http://www.arm.linux.org.uk/mailinglists/lists.php).

Definitely U-Boot.

Don't know about uCos, so I can't tell. Anyway you also need to make
sure that the license of your uCos drivers is GPLv2, another
compatible license, or that you are the author of these drivers and
that you can re-license them under GPLv2.

Sincerly,
