Some hardware, such as the enhanced local bus controller used on some mpc83xx chips, does ecc transparently when reading and writing data, rather than providing a generic calculate/correct mechanism that can be exported to the nand subsystem.
The subsystem should not BUG() when calculate, correct, or hwctl are missing, if the methods that call them have been overridden.

This should go through the 83xx custodian, but I haven't seen this yet?
Why should it go through 83xx? It's a patch against generic NAND code.
It seems to be 83xx specific code to me?
It's not. It is removing a restriction in the NAND code that happens to interfere with what the FSL NAND driver needs to do.
Did you try applying it against the 2.6.22.1 branch of the nand repository (IIRC, the non-commit-message patch comment specified that)?
No, I tried to apply this to the U-Boot repository. Maybe this was my fault? Is this supposed to go into Linux, then?
No, it's supposed to go into the 2.6.22.1 branch of Stefan's u-boot NAND tree. This change is already in the Linux NAND code.
