      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.
