Come on, is it really that big a problem?
You define all your needed settings (foo, bar, baz, and maybe uuid),
and then you run a single command
setenv bootargs "${foo} ${bar} %{baz} ${uuid}"
?
Yes, it takes one additional step, but it's simple and does not need
extra code.
[And if someone bothered to update hush to a recent version, and
while doing so revisited the adaptions needed for U-Boot, we could
also do much better. IIRC, things like command substitution were
omitted then because of the code size it would have required; given
today's resources this might be an optional feature for many.]
Best regards,
Wolfgang Denk
