No, we don't have this yet in U-Boot.

But that's a small problem - as long as we just need to parse for  an
expression  like "eth\d*addr" we can easily do this with ten lines of
C or so.

If we find we might need sscanf() more often, we might een go as  far
and   borrow   some   200+  lines  of  code  for  Linux  (i.e.,  from
"lib/vsprintf.c") :-)

Best regards,

Wolfgang Denk
