Steps to build the kernel:

Download and install the cross toolchain gcc version 3 for Linux 2.4.

$ cd /opt
$ tar xzf mipseltools-gcc331-lnx24.tar.gz
$ export PATH=/opt/mipseltools-gcc331-lnx24/bin:$PATH

Download the linux kernel tarball celinux-040503.tar.bz2 and unpack it:

$ tar xjf celinux-040503.tar.bz2

Download the latest kernel patch and patch it to the kernel tree:

$ cd celinux-040503
$ gzip -cd ../celinux-040503-jz-yyyymmdd.patch.gz | patch -p1

Make defconfig of the JZSOC based platform, eg:

$ make defconfig-pavo (JZ4740 PAVO board)
$ make defconfig-pmpv2 (JZ4730 PMP Ver 2.x board)
$ make defconfig-virgo (JZ4720 VIRGO board)

Build the kernel:

$ make xconfig
$ make dep
$ make uImage or make zImage

To build the celinux kernel, you need to install a mipsel-linux-gcc
version 3.3.x.
