This allows us to do basic math in hush shell. For example:
U-Boot# r1=10
U-Boot# r2=20
U-Boot# setexpr.l r3 $r1 + $r2
U-Boot# echo $r3
30

This needs to be done in the configs/ files now instead as we have
CMD_EXPR there. In fact I'm not sure right now which would win, the
define here or the disable currently in the config files :)
yeah, I do many defconfigs define CONFIG_CMD_SETEXPR..
We dont have a common config file there(similar to ti_armv7_common) ..
we'd have to introduce this for every board config then... is'nt that
in-efficient?
Much like the kernel we try and pick sensible defaults. In this case
you'd be removing a line from the defconfig files.
But you're not the first to suggest that something better could be done
here and maybe further down the line we'll play with the upstream tools
for merging defconfig snippets so that we could have some common ones
pulled together.
I just curious whether setexpr.l will work with 64bit variable, which
required to represent initrd address with LPAE enabled. Does the
setexpr have uint_64_t version?
