Seeking I2C Driver for MPC824x (kurobox/HG)

[Eiji Kawauchi <kawauchi@pa.air.jp>]

かわうちと申します。現在、玄箱/HGにNetBSD/sandpointを移植しています。

だいたい動いたのですが、MPC824x用のI2Cドライバで困っています。
現在はモトローラのDINK32のサンプルコードにラッピングして動かしているの
ですが、どこかに(ちゃんとした;-)ドライバは無いでしょうか。
情報をお持ちの方が居られましたらよろしくお願いします。

# 自前で途中まで書いたのですが、どうもうまく動かないのです...

以下、ちょっと長いですが、現時点のブートメッセージを付けます。
