Subject: [PATCH] mtd: rawnand: brcmnand: improve hamming oob layout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The current code generates 8 oob sections:
S1 1-5
ECC 6-8
S2 9-15
S3 16-21
ECC 22-24
S4 25-31
S5 32-37
ECC 38-40
S6 41-47
S7 48-53
ECC 54-56
S8 57-63
Change it by merging continuous sections:
S1 1-5
ECC 6-8
S2 9-21
ECC 22-24
S3 25-37
ECC 38-40
S4 41-53
ECC 54-56
S5 57-63

Subject: [PATCH] mtd: rawnand: brcmnand: correctly verify erased pages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The current code checks that the whole OOB area is erased.
This is a problem when JFFS2 cleanmarkers are added to the OOB, since it will
fail due to the usable OOB bytes not being 0xff.
Correct this by only checking that data and ECC bytes aren't 0xff.
Fixes: 02b88eea9f9c ("mtd: brcmnand: Add check for erased page bitflips")
