When computing oobavail from the list of free areas in the OOB, don't assume there will always be an unused slot at the end.
Signed-off-by: Sandeep Paulraj s-paulraj@ti.com --- Applies to u-boot-nand-flash/next This particular issue was found by TI while testing the DaVinci DM3xx with new 4 KB page sized NAND devices. I am going to attempt to send patches to sync up the MTD NAND driver in u-boot with what is in the kernel.I am already using this feature in our internal releases. drivers/mtd/nand/nand_base.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-)
