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.
