[U-Boot] Issue with running commands

[Sughosh Ganu]

hi,
While testing on hawkboard with the latest commit, i hit an issue of
commands not being accepted.

hawkboard > reset
Unknown command '�����' - try 'help'
hawkboard >

Running git bisect showed that this is caused due to commit 054ea170f271:
cmd_mem: cmp: unify size code paths. Has anyone seen this issue -- i don't
think this is board/arch specific.
