Did you find any differences in the NAND code? > And I have no chance to detect this difference, when using > "git am -3 ..." ... it just remains in the code ... > > I vote for copying the linux files, marking U-Boot specific code > with __UBOOT__ ... Yes, the 3-way merge approach requires that we know where and when the old code came from. Unfortunately that information is not present outside of drivers/mtd/nand, so for those directories starting from scratch is reasonable (unless we can figure it out based on when the code was added to U-Boot...). Once that's been done, future updates can be done with 3-way merges. I still disagree with #ifndef __UBOOT__ as it will hurt more than it helps with future merges. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
