Here a few examples: Boards with NAND: omap3_beagle: ~5k increase Boards with NOR : TQM5200: ~7k increase I have to admit that this is more than I expected. After thinking a bit more it came to my mind that I don't need to add mtdcore.o and mtdpart.o for those boards. mtdcore is sufficient and mtdpart is only needed for UBI support right now. So I only enabled mtdcore creation for those boards and here are the new results: omap3_beagle: ~800 bytes increase TQM5200: ~2k increase This looks much better. I'll wrap up another patch with this new structuring shortly and perhaps I'll create a branch in my u-boot-cfi-flash repository for all those MTD infrastructure changes so that users and board maintainers can easier test those changes. Thanks.
