That's currently not the case. At least some MVEBU (Armada XP / 38x)
boards don't have it enabled. Here a short (most likely incomplete)
list:

clearfog
db-88f6820-gp
db-mv784mp-gp_defconfig
ds414
maxbcm

And probably some (most?) Orion & Kirkwood based board as well. I
assume that most boards that include "mv-common.h" have it not
enabled (I didn't check all of them).

Some board, like theadorable have HUSH support enabled but
CMDLINE not. These boards are not broken.

Run-time.

Thanks,
