So, I should copy whole "mach-orion" folder to new kernel source tree, am I 
correct? An then what to do?

Sertac,

Starting point will be, arch/arm.
make 
  platform base CPU SoC code and serial up.
If u able to make these things 
  up, then its addition of pheripherals.

    Harishkumar,

    I already know my SoC name, it is Celestial CSM1203, 
    and it is not available in any official kernel source tree ( the last one I 
    checked it 3.4.1 10 minutes ago).

    Since it is not available in the original kernel 
    source, we had to make those thousands of changes one-by-one, and it would 
    take years, right?

    Am I correct?

Sertac,

Also, if u know ur chip SoC name, u can find 
      whether open source linux kernel may have already support inbuilt in it. u 
      can google around it, before deciding to port.

      Sertac,

From your present source, u can find 
        the Celestial SoC change.
check for arch/arm folder. 

then in 
        corresponding drivers, like usb,serial,video etc.

          Dear Harishkumar;

          Thank you very much for your quick

          Where can I find related Celestial SoC & 
          driver patch file?

Sertac,

Basically u need to have Celestial SoC 
            & drivers related patch.
Then, u can download desired kernel 
            or latest 3.3.x.

Apply and do the forward porting. It won't 
            be straight forward, u need to re-write a bit.
U can always refer 
            any other celectial SoC family in latest kernel source or other ARM9 
            family.

see -> arch/arm/

              Dear All;

              I have a digital satellite receiver (named 
              Chipbox), which uses linux kernel 2.6.12.5.

              Main chipset name is Celestial CSM1203 ( It 
              is ARM926EJ-S core).

              The original kernel source (and all other 
              sources) can be downloaded here: http://www.merihvideo.com.tr/chipbox-source.php

              I would like to add some functionality (Such 
              as CIFS, USB WIFI...) to my STB. In order to do that, I need to 
              cross compile new kernel.

              However, the chipset provider ( Celestial) 
              does not provide a new kernel to do this. They just compiled 
              2.6.12.5 for about 5-6 years ago, and they didn't do a new kernel 
              from that time.

              So, I need your helps:

              1) Celestial has done a lot of modifications 
              on the original 2.6.12.5 source ( drivers, headers, 
              definitions...) All these changes can be seen by using MELD 
              tool.

              2) In order to have a new kernel ( Such as 
              2.6.35.13) which can be running on my chipbox, what are the steps 
              should be done one by one?

              Can you please explain for a newbie 
              please?

              Best Regards

              Sertac
