Hi Sean:
 
I will withdraw this patch. I had a talk with the U-Boot guys. The reason for this
patch was to support those guys that had their ECC ordering at (213) on the older
version of the kernel. Upgrading to (123) may be problematic. Since without a jtag
it would be a bit complex.
 
I still think this NAND_ECC_SMC define is somewhat missleading. Given that
both 1-2-3 and 2-1-3 are supported by the correction routine.

Did you actually find a 44x PPC core that is not NAND_ECC_SMS format?
