Hello all,

     I'm porting Linux 2.4.25 at my MPC852T.My first used is 2.4.4, I assign my board info ptr to 0x3400 and pass it to linux 2.4.4.
It works fine. But 2.4.25's head.S changes much code  I don't know how to porting it. I need help.

My add code  like this

li    r3, 0x3400
mr r11,r3 
(../arch/ppc/mbxboot/head.S)

to 2.4.4.

    Another question is where can i find older kernel like 2.4.10, 2.4.12,2.4.18 for PowerPC?I know DENX Linux kernel source tree
has the latest version, but i'm not sure there has above version that I want and I don't how to used cvs command to get it.If anyone
know where to download older kernel, please tell me,thanks.

Best Regards,
Rober Hsu

Ummm... are you sure you know what you are doing?

Just have  a  look  at  the  existing  code.  MPC8xx  is  a  standard
architecture and has been supported since a long,, long time ago.

You can find it for example in our CVS server.

If you don;t know the tools, and are not willing to try to  learn  to
use  these,  then  nobody  will  be able to help you. Try and hire an
expert.

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,

Specify image type "multi" when running the U-Boot "mkimge" tool.

This depends on the requirements. It may be very useful to be able to
change the application image while keeping the known  to  be  working
kernel constant.
