FreeBSD/ARM and FDT cleanup - status report #9

[Jakub Klama]

 Hi,

 It's ninth status report for project aimed to clean up
 current FreeBSD/ARM port and FDT implementation.

 Things done this week:
 * Improvements in arm machdep code, especially in pmap_devmap
   mapping code, allowing first-level nodes in DTS files to be
   mapped.
 * Trying to refactor mv port, but this will be not so easy,
   as mv window decode mechanism needs access to many different
   SoC registers at initarm() stage. I need to rethink some
   ideas of dynamic pmap_devmap mapping to handle this scenario
   properly.

 Plans for next week:
 * Think about passing trapframes in interrupt handlers in
   a way better than multiplexing it with user supplied argument
   in arm_intr_data structure.
 * Fix OMAP L2 cache controller issue

 Regards,
 Jakub Klama
