Hi Brian, Pekon,

I believe all of your queries have either been answered or addressed
and I am hoping this will be the last submission. :)

/me crosses fingers!

Kind regards,
Lee

I didn't look through the patches yet, but my build tools tell me you
didn't compile-test this. Please compile, test, and resend your patches.

In file included from drivers/mtd/nand/stm_nand_bch.c:26:0:

These are due to a CONFIG rename I did lastminute.com.  I fixed it
~2mins after sending the set and will re-send today.

Particularly, take a hard look at rewriting
include/linux/mtd/stm_nand_bbt.h.

I don't think there is any need - although this change is required:

-#if defined(MTD_NAND_STM_BBT)
+#if defined(MTD_NAND_STM_BCH_BBT)

drivers/mtd/nand/stm_nand_bch.c: In function 'bch_calc_timing_registers':
drivers/mtd/nand/stm_nand_bch.c:1022:6: warning: variable 'ren_half_off' set but not used [-Wunused-but-set-variable]
drivers/mtd/nand/stm_nand_bch.c:1021:6: warning: variable 'ren_half_on' set but not used [-Wunused-but-set-variable]

This I have never seen.  I guess -Wunused-but-set-variable is normally
off.  This issue has been present since the beginning of this endeavour
and exists in the original (internal) code.

Will fix.
