-Subject: [PATCH v2 1/2] mtd: nand: pxa3xx: Fix PIO FIFO draining
-
-The NDDB register holds the data that are needed by the read and write
-commands.
-
-However, during a read PIO access, the datasheet specifies that after each 32
-bits read in that register, when BCH is enabled, we have to make sure that the
-RDDREQ bit is set in the NDSR register.
-
-This fixes an issue that was seen on the Armada 385, and presumably other mvebu
-SoCs, when a read on a newly erased page would end up in the driver reporting a
-timeout from the NAND.
