You can use Ocotea code (kernel and/or U-Boot) as-is for your board only in one case - your board is _identical_ to Ocotea. I doubt that this is the case, so you have to modify U-Boot and/or kernel board support code to accommodate any differences between Ocotea and your design. Start with asking your hardware people about such differences. -- Eugene
