We need to address the redundat image case and undestand if the image is corrupted or not. In error case we need to try the fallback copy. The function used before was always return 0 without any evaluation of the error. We try to make it work properly Signed-off-by: Michael Trimarchi <michael@amarulasolutions.com> --- Changes V1->V2: Address the comments on using the err variable --- common/spl/spl_nand.c | 34 +++++++++++++++++++++++++--------- 1 file changed, 25 insertions(+), 9 deletions(-)
