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

	073f39c Browse files » MACH-S3C24XX: Add support for flash based BBT ... The default configuration of the current 2.6.37 kernel uses a flash based BBT. So, barebox must also use one, to be in sync with the kernel about bad blocks in the flash. Due to the used OOB layout, the generic BBT description coming with the framework can be used.
