Not if you want to read/write from/to the uboot partition from Linux.
Per-partition ECC setup is not supported, so the only solutions we have right now are: 1/ use the same ECC config as the one use by the bootrom 2/ only access uboot partition in raw mode from Linux (that implies generating images containing the ECC bytes so that they can be flashed to the device in raw mode) 3/ never access uboot partitions from Linux (not sure we want that)

Hm, I don't find it over-engineered.
