I can't seem to find anything that says we can do thus, but wondering if there was any way to get simple math (addition) out of the u-boot shell? Was looking for something like 'expr'.

hush doesn't do expressions - everything's a string - you need to import something like shell/ash.c from the busybox package into u-boot. If you have an extremely limited amount of math, it can be done with trivial comparison logic already available in hush.

btw, u-boot users and developers should start prepending new hex values with "0x", btw.
