      Staging: Add SBE 2T3E3 WAN driver · 921a86e0
      Krzysztof Halasa authored 
      This is a driver for SBE Inc.'s dual port T3/E3 WAN cards. Based on
their original GPLed driver.

The original driver tarball is now accessible at
http://userweb.kernel.org/~chris/SBE_2T3_Linux_2.0c.tgz

It needs at least a new generic HDLC setup code (not yet written) before
moving to drivers/net/wan.

      Future patches should fix this up.

      Staging: add West Bridge Astoria Driver · 81eb669b
      David Cross authored 
      This is a driver for the Cypress West Bridge companion chip. Its
function is analogous to the North/South Bridges of PC environments
applied to embedded devices, in that it expands I/O and storage
capabilities of an embedded processor. The Astoria version, which this
driver applies to, functions as a USB, embedded memory and SDIO
controller. The kernel that this patch was applied to is linux-2.6.35,
although it was tested using the android kernel 2.6.29 running on the
Zoom 2 platform. In this system, it was used primarily as a sideloading
accelerator enabling direct data transfers between a USB host PC and
embedded memory without system overheads.  Minor modifications were also
made to the kernel for this patch. These include changes such as
EXPORTing of fat_get_block in the kernel code. Another function,
mpage_cleardirty was also added to the memory management code. This
function is used to clear the dirty pages from a specific inode. This
allows for direct, file based DMA. None of these changes are believed to
have any negative impact on the kernel and may provide additional
benefit for other developers and drivers.

The driver, as submitted, was placed into the drivers/staging/westbridge
folder as the directory structure it will eventually reside in is not yet
defined. The driver, as placed in staging is divided into four parts:
1) gadget - this implements a gadget peripheral controller and includes IOCTLs
for MTP transfers
2) block -this implements a generic block device driver to enable access to
embedded memory
3) api -this is the Cypress SDK, and includes USB and Storage specific
functions. In addition, it includes common code for low level routines such as
message passing and common data transfer routines
4) hal - this should likely be included in the arch directory as it needs to
be modified for a given platform. The directory structure in the staging area
is meant to reflect the eventual location of where this code likely should be.
It is platform specific. In this case, the HAL included is for the Android
Zoom 2 platform. Here, West Bridge is connected to the GPMC (general purpose
memory controller) of the OMAP3. Specific timing needs to be enabled to ensure
reliable communication.
Many thanks to Greg KH for conducting initial reviews and providing pointers.
