Re: [U-Boot] Broken ecc.size when switching between sw and hw ecc (beagleboard)

ECC mode is normally not something that you want to be runtime switchable, as changing it usually changes the on-flash format. It also requires driver cooperation -- the actual implementation (as opposed to the command-line wrapper) is in drivers/mtd/nand/omap_gpmc.c.

Are you saying that it shouldn't be switchable through a command line option (but rather based on information in the partition table or something similar), or are you saying that we shouldn't need different ECC modes for different parts of the flash (boot ROM vs. software implementations, whether block 0 has different ECC requirement etc)?
