From: David Brownell Date: Fri, 15 May 2009 21:47:13 +0000 (+0200) Subject: davinci dm6446evm NAND update X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=269dfea017b09c5a999d3053d00505c19789c350;p=project%2Fbcm63xx%2Fu-boot.git davinci dm6446evm NAND update This updates the optional (non-default!) NAND support for the DaVinci DM6446 EVM: - include MTD partitioning, defaulting to what Linux uses - use a flash-based BBT, which among other things speeds bootup This matches code that's now queued for mainline Linux, and might even merge in an upcoming 2.6.30-rc; and the MTIDS are set up so that the U-Boot $mtdparts environment variable can be passed as-is on the kernel command line as a cmdlinepart override.
