OMAP34xx HW 1-bit ECC algorithm

Is there any source for code that generates a 3-byte subpage ECC that matches the ECC the bootrom is expecting when reading bootloader code out of the first block of NAND?

I'm dealing with a problem of the Micron MT46H256M32L4K1-5 that has a in-chip BCH ECC engine on our boards where a reset doesn't clear the in-chip ECC. The in-chip ECC resides at bytes 8-15, 24-31, 40-47, 56-63 of the OOB, and the first half-page ECC overlaps the 3rd and 4th page HW 1-bit ECC. I need to synthesize data in the 3rd/4th subpages for the code loaded from the bootloader that matches bytes 8-12 of the Micron in-chip ECC.

Thanks in advance!
