Hey All;
   
   I've got a series of kernel patch files to provide support for a new board.
What I'd like to know is where to place  board specific kernel   config  information.
 
Are there any docs on the build-system layout for implementing new board support ?

  I've  got my kernel patch files  under  target/linux/ixp4xx/patches-2.6.32
  my board profile under target/linux/ixp4xx/generic
  Am I suppose to stick my kernel config  settings  in the  target/linux/ixp4xx/config-default ?

It builds and loads if I just replace the config-default with a  .config file from a configured kernel source tree.
Also what files must I edit to get an image file built for the board ? 
This board requires the kernel on the same filesystem as the image so I assume as custom image build script is in order.

Thanks for any help  or  pointers to docs .

Thanks;  I looked at that documentation.

I guess I'm just a little confused about placement of patches for a "board profile".

  I've got the kernel patches for a new  ixp4xx board.
  I placed the patches under  target/linux/ixp4xx/patches-2.6.23 directory

  Most of the patches should apply fine to the main  target/ixp4xx/patches -2.6.23 directory, but I think there are 3 that may muck up other board-profiles.

  Where could I place patches that are specific to my board's profile so I don't muck up other ixp4xx targets during a build ?
  or do I simply create a new target arch type  and place them under there ?

If I get this patch placement sorted out today  I can chuck a test-patch set up on the developers mail-list .
