Last change on this file since db5651c was db5651c, checked in by Waldemar Brodkorb <wbx@…>, 19 years ago

merge wbx-target-cleanup to trunk.

  • mk directory for some top level makefiles (build.mk,vars.mk)
  • add a separate configfs partition to all models, 128 kb big
  • add model and platform specific startup files and kernel configs
  • delete target/linux/package, add all addon kernel packages to packages
  • simplify target/linux/brcm-2.4/Makefile, abstraction to mk/ comes later
  • add target/image directory, place where the different images are created
  • default off for all extra packages, be sure that you enable all packages you need to get a dsl-capable router. snapshots will be created by a specific config which contains all needed stuff (iptables, pppoe, pptp, haserl, webif)
