[PATCH] board_nokia770: add hwa742 platform data

[Arnaud Patard (Rtp) <arnaud.patard@rtp-net.org>]

[-- Attachment #1: Type: text/plain, Size: 311 bytes --]


The n800fb changes introduced some platform_data for the hwa742 and
needs now to be defined for getting it working.  This patch adds the
necessary bits needed for getting fb working again on n770.
This patch comes from the n800 kernel from maemo.org
