	e0965c4 Browse files » S3C24xx/NFC: Consider correct NAND page size for boot. ... When booting from NAND, its important to know the correct page size. When the NAND is used as the boot source, four dedicated pins are used to configure the correct page size and address cycles. These pins can be read back in one of the NFC registers to parametrize the load function. This patch also extends the read routine to support more than four address cycles on demand. BTW: At least some mini2440s are misconfigured to use five address cycles for a NAND device that is known to need only four address cycles. In this case the vendor is at our side: This NAND simply ignores any additional address cycles than required.

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
