OMAP34xx HW 1-bit ECC algorithm

OMAP34xx HW 1-bit ECC algorithm

[Peter Barada]

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!
