about linux 2.4.25 on MPC852T

Hello all,

     I'm porting Linux 2.4.25 at my MPC852T.I can make uImag and ramdisk.tar.gz  now.
My question is how to combine these two file to linux.bin  let linux auto mount ramdisk.image.gz.
I think one file would be easy to maintain and download.

PS:I used 2.4.25 and u-boot 1.1.3.I want linux.bin = uImage+ramdisk.image.gz and let u-boot autorun linux.bin 
      at board start up. 


Best Regards,
Rober Hsu
