[U-Boot] [PATCH] ARM DaVinci Leopard Board Support
s-paulraj at ti.com

Wed May 13 16:32:40 CEST 2009
The patch applies to arm/next. It was tested on a leopard board.
After testing had to change the MACH TYPE as this board is not present
in the list of mach types at the moment. So the patch itself is going
to give a compilation failure.
Further details on this board can be found at www.leopardboard.org
This patch does not do the NAND initialization yet. Will send an update
to this patch after David Brownell's NAND updates get merged
Jean-Christophe can you please do a new sync for this board
