[U-Boot] Issue with running commands

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.
