[U-Boot] [PATCH V2 1/3 CORRECTED] Initial support for Marvell Orion5x SoC
Albert Aribaud
albert.aribaud at free.fr
Sun Nov 15 08:56:57 CET 2009
** ATTENTION: this patch supersedes the previous '1/3' patch in
the same series. The correction is the removal of Kirkwood-inherited
device init code unused at the moment and partly inapplicable to
Orion5x anyway. This correct patch has been run through checkpatch.pl
again with the exact same result as its predecessor (6 false pos).
Sorry for the inconvenience.
This patch adds support for the Marvell Orion5x SoC.
It has no use alone, and must be followed by a patch
to add Orion5x support for serial, then support for
the ED Mini V2, an Orion5x-based board from LaCie.
