So the bug you've found is that we don't parse "bootm #conf at 2"
correctly.  We cannot change what has been working and is likely in the
wild of "bootm ${loadaddr}#conf at 2".  I think what we have to do here is
correct the syntax file here to note that addr1 is not optional in that
case and add a new form.  I would first suggest seeing how it looks in
code to have "bootm conf at 2" just work.   If it ends up being too tricky
or complex, "bootm _conf@" is OK as the new one.
