1. Install Tool Chain for RedBoot
% tar zxfv i686-pc-linux-gnulibc2.2-x-xscale-elf.tar.Z
% cp i686-pc-linux-gnulibc2.2-x-xscale-elf/ H-i686-pc-linux-gnulibc2.2 /opt/redhat/ xscale-030422
% cd /opt/redhat/xscale-030422/H-i686-pc-linux-gnulibc2.2/bin
% ln -s xscale-elf-gcc arm-elf-gcc
% ln -s xscale-elf-ar arm-elf-ar
% ln -s xscale-elf-objcopy arm-elf-objcopy
% export PATH=/opt/redhat/xscale-030422/H-i686-pc-linux-gnulibc2.2/bin:$PATH
2. Building Redboot
