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.
