[PATCH] OneNAND: Simple Bad Block handling support

[Kyungmin Park]

Hi

Which directory are you patch? MTD-CVS or kernel?

In MTD-CVS I also have similar message 

$ patch --dry-run -p1 < ../onenand-bbm.patch
patching file drivers/mtd/onenand/Makefile
Hunk #1 FAILED at 3.
1 out of 1 hunk FAILED -- saving rejects to file
drivers/mtd/onenand/Makefile.rej
patching file drivers/mtd/onenand/onenand_base.c
Hunk #1 FAILED at 311.
Hunk #2 succeeded at 1033 (offset -29 lines).
Hunk #4 succeeded at 1158 (offset -29 lines).
Hunk #6 succeeded at 1504 (offset -35 lines).
1 out of 6 hunks FAILED -- saving rejects to file

Hunk #3 FAILED at 101.
Hunk #4 succeeded at 109 (offset -1 lines).
1 out of 4 hunks FAILED -- saving rejects to file
include/linux/mtd/onenand.h.rej

I think the patch scenario is following

1. patching onenand-syncread.patch (check previous e-mail)
2. onenand-bbm.patch
3. omap-onenand.patch

Try again and If you have same problem. please let me know

In my test there's two .rej file

./drivers/mtd/onenand/Makefile.rej
./drivers/mtd/onenand/onenand_base.c.rej

I tried to solve this problem

Thank you
