How to use an existing cross compiler / boards to make an Emdebian distribution ?

[张增波 <zengbo.zhang@gmail.com>]

Hi all,
I am an new "em-debianer"。I am working on an existing ARM9 based board,
the cpu manufacturer provide us an cross compiler and an modified
version of Kernel , Uboot, and basic root filesystem plus some libraries
dedicated to this chip。After searching real-world approachs to manage
the embedded linux packages ,I found that the emdebian way is the best
。So I want to use the debian package mechnism to manage many open
source packages, but I don't know how to use an existing compiler (which
is not generated by emsetup、emchain) to make such an "distribution".
Could any one give me some suggestions or guides or even hints?
