+Subject: [PATCH] [PATCH] Rework the OHCI quirk mecanism as suggested by David
+
+This patch applies David Brownell's suggestion for reworking the
+OHCI quirk mechanism via a table of PCI IDs. It adapts the existing
+quirks to use that mechanism.
+
+This also moves the quirks to reset() as suggested by the comment
+in there. This is necessary as we need to have the endian properly
+set before we try to init the controller.

+Subject: [PATCH] [PATCH] Implement support for "split" endian OHCI
+
+This patch separates support for big endian MMIO register access
+and big endian descriptors in order to support the Toshiba SCC
+implementation which has big endian registers but little endian
+in-memory descriptors.
+
+It simplifies the access functions a bit in ohci.h while at it.

+Subject: [PATCH] [PATCH] ohci: Rework bus glue integration to allow several at once
+
+The previous model had the module_init & module_exit function in the
+bus glue .c files themselves. That's a problem if several glues need
+to be selected at once and the driver is built has module. This case
+is quite common in embedded system where you want to handle both the
+integrated ohci controller and some extra controller on PCI.
+
+The ohci-hcd.c file now provide the module_init & module_exit and
+appropriate driver registering/unregistering is done conditionally,
+using #ifdefs.

+Subject: [PATCH] [PATCH] ohci: Add support for OHCI controller on the of_platform bus
+
+PPC embedded systems can have a ohci controller builtin. In the
+new model, it will end up as a driver on the of_platform bus,
+this patches takes care of them.

+Subject: [PATCH] [PATCH] powerpc: Add a unified uevent handler for bus based on of_device
+
+This common uevent handler allow the several bus types based on
+of_device to generate the uevent properly and avoiding
+code duplication.
+
+This handlers take a struct device as argument and can therefore
+be used as the uevent call directly if no special treatment is
+needed for the bus.

+From: Grant Likely <grant.likely@secretlab.ca>
+Date: Mon, 4 Dec 2006 22:29:03 -0700
+Subject: [PATCH] [POWERPC] Make FEC work on the lite5200
+
+This patch may very well break Eth support on the Efika, and it's not
+very pretty. But is works well enough for an NFS rootfs. This also
+makes major bestcomm changes by removing Efika-specific bestcomm
+support and porting the arch/ppc bestcomm support driver which
+was posted to linuxppc-embedded about a year ago.

+[POWERPC] Efika: Add missing interrupts from bestcomm node
+
+The efika device tree does not have the list of bestcomm interrupts which
+are expected by the Linux 52xx bestcomm device driver. This adds the
+expected properties
