[U-Boot-Users] Porting U-Boot on to Cogent CSB535FS

[Midhun Agnihotram]

Hi Txema,

   I will indeed use your patch. But I would also like to have some
pointers as to how to develop this patch. I am new to the embedded
world although not that new to Linux. I want to fully port U-boot to
CSB535FS as we require the support for SD card and Compact Flash.

  How do I start porting U-Boot to a new board? I have read the README
of U-Boot. And I know that I need to set a lot of parameters - but
they are Greek and Latin for me. How do I start off? Any web sites??
Books?? Links?? Were do I get these parameters from?? From the board
manufacturer / supplier??


  Thanks and Regards,
  Midhun Agnihotram.
