David, I see the point you are trying to make.
Strictly speaking what I have done is correct. The issue is we need A different U-Boot(which I am using with the appropriate layout and all the NAND driver enhancements that I submitted to linux-mtd which I ported to U-Boot) and also the kernel NAND driver changes. Also the davinci git does not have all the stuff that you and I have have submitted to linux-mtd. Afcourse it is in my branch. I also see that in the DM355 board specific code you use NAND_ECC_HW_SYNDROME. BTW you have access to the LSP 2.10 beta release. In the GA release we rectify the layout issues. The GA release NAND drivers are same as what we submitted many moons ago in March. But even then there will be differences in the layout itself between the LSP 2.10 GA release and what we have in place at the moment.
