Makefile

   1 # Makefile for building the IXP4xx kernel.
   2 #
   3 #  Based on the build script for the Loft from Giant Shoulder, Inc.
   4 #    written by Tommy B.
   5 #  Based on the great work done in OpenEmbedded for the Linksys NSLU2
   6 #    written by the nslu2-linux development community.
   7 #
   8 #  This builds the kernel in the linux-${REVISION} directory.
   9 #  It then installs all the kernel modules in lib
  10 #  and creates a tarball there containing all the modules
  11 #  under the lib/modules/${REVISION} directory.
  12 #
  13 #  N.B. You may need to change your crosstool path
