2011-12-22	88ce7ef Browse files » drivers/mtd: transfer NAND notions to MTD core ... Change NAND_WRITE into MTD_WRITE. Change "page_shift" references in the core, which are purely NAND, into mtd->writesize which is MTD generic. Rename all "info" (struct mtd_info) into "mtd". Also provide a parameter to add_mtd_device() so that legacy nand devices still appear as nand<N>.

2011-03-03	5fb8333 Browse files » ARM i.MX: cleanup boot modes ... The i.MX Processors support two different boot modes, the internal boot mode and the external boot mode. Traditionally the external NAND boot mode is handled in drivers/mtd/nand and the internal boot mode is handled in arch/arm/mach-imx. This patch consolidates the handling of both boot modes in arch/arm/mach-imx so that the user does not have to look in the mtd kconfig section for booting from NAND. Also, selecting between internal and external boot mode now is a clear choice. The external NAND boot mode has been independent of the mtd nand driver, but as the code was contained in the NAND driver it was not possible to support booting from NAND without a mtd nand driver. This is changed with this patch. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 3 Mar 2011

	5fcca46 Browse files » imx nand: move initialization to preset function ... This has two purposes. First we need to factor out initialization to be able to do something different on v3 type controllers, second with this patch we are independent of preinitialized register values.

	da1ad19 Browse files » mxc_nand: fix correct_data function ... The v2 controller has a totally different mechanism to check whether the data we read had ecc errors or not. Implement this. The mechanism in the v2 controller happens to be identical to the v3 controller. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 12 Nov 2010

	bb81ff7 Browse files » imx_nand: rework get_dev_status ... We save/restore the value in the buffer anyway, so it makes no difference whether we use main_area0 or main_area1. So, we can use main_area0 and remove main_area1 from the driver which is otherwise unused. Also, clean up the comments in get_dev_status.
