+
+ [PATCH] nand: Fix problem with oobsize calculation
+
+ Here the description from Brian Brelsford <Brian_Brelsford@dell.com>:
+
+ The Hynix part returns a 0x1d in the 4th ID byte. The Samsung part
+ returns a 0x15. In the code fragment below bits [1:0] determine the
+ page size, it is ANDed via "(extid & 0x3)" then shifted out. The
+ next field is also ANDed with 0x3. However this is a one bit field
+ as defined in the Hynix and Samsung parts in the 4th ID byte that
+ determins the oobsize, not a two bit field. It works on Samsung as
+ bits[3:2] are 01. However for the Hynix there is a 11 in these two
+ bits, so the oob size gets messed up.
+
+ I checked the correct linux code and the suggested fix from Brian is
+ also available in the linux nand mtd driver.
