Author: sparky

New Revision: 6783

Added:
   ppcrcd/trunk/fill_conf.pl   (contents, props changed)
   ppcrcd/trunk/mkvmlinuz   (contents, props changed)
Modified:
   ppcrcd/trunk/Makefile
Log:
- mkvmlinuz: stripped and a little changed script for preparing bootable
  ppc kernel image
- fill_conf.pl: script filling yaboot configuration
- Makefile: prepare vmlinuz - chrp-bootable image with initrd;
  ppcrcd will work on pegasos 2 soon !!!
