-Subject: [PATCH] mtd: pxa3xx_nand: Fix initial controller configuration
-
-The Data Flash Control Register (NDCR) contains two types
-of parameters: those that are needed for device identification,
-and those that can only be set after device identification.
-
-Therefore, the driver can't set them all at once and instead
-needs to configure the first group before nand_scan_ident()
-and the second group later.
-
-Let's split pxa3xx_nand_config in two halves, and set the
-parameters that depend on the device geometry once this is known.
