-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
