Subject: [PATCH 0/7] mtd: rawnand: sunxi: Bug fixes and cleanup

I have an A33 tablet with MLC NAND, and I wanted to use mainline Linux
to dump the NAND. To do that, I updated this driver's ECC ops to fully
utilize the hardware for ECC and scrambling. This made the driver
compatible with the existing (scrambled) on-flash bad block map, and I
was able to read the full NAND contents.

This series contains some initial bug fixes and cleanup from that
effort. The changes to the ECC ops will come as a separate series.
