[Ghorai] Agree, the NAND type (i.e. x8 NAND or x16 NAND) is a board specific, So I will change the definition of board_nand_init() to pass the devsize form board file. And I will submit the patch-series again. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH 1/7] omap3630: nand: fix device size to work in polled mode
zoom3 and 3630-sdp having the x16 nand device. This patch configure gpmc as x16 and select the currect function in driver for polled mode (without prefetch enable) transfer.
