[U-Boot] [PATCH v2] ppc4xx: Add CATCenter Io 405EP board support

Dirk Eibach eibach at gdsys.de
Wed Oct 13 12:20:18 CEST 2010


Board support for the Guntermann & Drunck CATCenter Io.

Signed-off-by: Dirk Eibach <eibach at gdsys.de>
---
Changes since v1:
- added MAINTAINERS entry
- sort MAKEALL
- whitespace/codestyle cleanup
- use boards.cfg instead of Makefile
- added some comments for clarification
- use CONFIG_BITBANGMII_MULTI
