For i.MX31 3stack (a.k.a. PDK) there's really not that much porting that needs to be done. mx31 is supported in U-boot so the following is needed: * Update my basic i.MX31 PDK patch to apply on top of the current U-boot git (it's been a while since I updated it) * Add the NAND SPL patch I mentioned in my previous reply (update it with the review comments) * Test and submit the patches The above could be done in a couple of days if your're familiar with i.MX31 and U-boot. Add more time if you're a newcomer to U-boot and/or i.MX31. Since Freescale hasn't published much info on i.MX35 or the 3stack for that I can only guess that it would probably be pretty straight forward to do a NAND SPL for i.MX35 based on the one for i.MX31 (the NAND controller and possibly the SDRAM controller on i.MX35 seems to be different from i.MX31).
