Linux kernel for MIPS architecture

["santosh kumar gowda" <ipv6_san@rediffmail.com>]

Hi,
I want to compile the entire Linux Kernel 2.4.20
for MIPS architecture.
I have mipsel-linux-gcc cross compiler.
Is this cross compiler enough or i need something else..??
Can any one suggest me from where to start with...??
What changes to be made in the Makefile..???
