I think you can avoid this define altogether, you're using it anyway.
Hi Marek,
I'm not sure I understand.
I need to define CONFIG_REVISION_TAG in order to get bootm to add
the tag:
http://git.denx.de/?p=u-boot.git;a=blob;f=arch/arm/lib/bootm.c;h=afa0093df7620606ee12b4dc1dd2ee37adee347c;hb=master#l137
I made get_board_rev() conditional so we can get rid of it if (once)
we're only using DT kernels.
