Today I used crosstool to create an arm-linux cross-compilation toolchain

Today I used crosstool to create an arm-linux cross-compilation toolchain, and successfully compiled and ran u-boot-1.3.0.
Learn about crosstool at http://www.kegel.com/crosstool/.
The cross-compilation toolchain version to be created is 3.3.2.
The specific steps are as follows:
Download crosstool-0.43.tar.gz
mkdir /home/wxm/crosstool
cp crosstool-0.43.tar.gz /home/wxm/crosstool
cd /home/wxm/crosstool
tar -jxvf crosstool-0.43.tar.gz
mkdir downloadsDownload
source package:
binutils-2.15.tar.bz2
gcc-3.3.2.tar.gz
glibc-2.3.2.tar.gz
glibc-linuxthreads-2.3.2.tar.gz
linux-2.6.9.tar.bz2Copy
to /home/wxm/crosstool/downloadsModify
arm.dat
KERNELCONFIG=`pwd`/arm.config
TARGET=arm-linux
TARGET_CFLAGS="-O"
Modify demo-arm.sh:             
#!/bin/sh
# This script has one line for each known working toolchain
# for this architecture. Uncomment the one you want.

# Really, you should do the mkdir before running this,
# and chown /opt/crosstool to yourself so you don't need to run as root.
