ok, then start with that. But, do understand the normal kernel changes betwwen ur kernel source and current one.

    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.

        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.

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.

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
