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 product from LaCie.
Signed-off-by: Albert Aribaud <albert.arib...@free.fr>
---
V1 of the patch was monolithic
V2 contains a number of fixes as a result of the V1 review,
and notably:
- is split in three patches : orion, serial, edmini;
- has been checkpatch'ed, with only 6 errors, in patch 1/3,
all 6 errors being false positives.
V3 contains yet several fixes as a result of the V2 review,
and notably:
- removes most of the GPIO and MPP programming support;
- adds low level init and removes CONFIG_SKIP_LOW_LEVEL_INIT.
