[U-Boot] [PATCH v3 14/23] km-arm: i2c support for suenx based boards

Heiko Schocher hs at denx.de
Mon Mar 21 08:02:10 CET 2011


This patch renames the suen3 defines and functions to KM_KIRKWOOD
which is more generic and more precise, because these values
and functions where used by all suenX boards and not only suen3.
