David Brownell <david-b@pacbell.net>:

Update the Beagle setup:

 - OMAP3530 updates:
    * split ICEpick TAP enable support to its own file, for
      reuse and eventually for storing other utility code
      like emulation reset
    * clean up, including labeling the tap as for DAP not
      for the Cortex-A8 and making endianness non-variable
    * add a few FIXMEs

 - BeagleBoard cleanup:  there's no SRST, "endstate" is gone, etc

I'm not sure I'd say it's further than "barely limping" just yet.
Key issues remain lack of Cortex-A8 support, and more complete
support for resetting.
