Message-Id: <1238622396-9768-1-git-send-email-marcel@ziswiler.com>

Subject: [PATCH] QE USB Host Integration for MPC832x
Open issues:
- MPC832x_MDS seems to lie about BCSR12_USMODE bit.
- How to use qe_setbrg() with an external clock pin? Hard-coded for now.
- How to properly allocate USB pram on MPC832x as standard layout won't work.
- Detects USB device plugged in but then hangs.
Please CC me personally when answering/commenting my posting, thanks.
