FreeBSD/ARM and FDT cleanup - status report #4

[Jakub Klama]

 Hi,

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

 Things done this week:
 * Made changes to interrupt routing code and modified arm ports
   in a way that old and new code can easily coexist: legacy arm
   ports use standard intr.c code, while lpc port uses intrng.c
 * Written geom slicer which will be used to map flash device
   partitions using data read from .dts files.
   I'm currently waiting for OpenRD-Client which has NAND and NOR
   flash onboard and allow me to test this changes. It should
   arrive in few days.

 Things for next week:
 * Test geom changes on OpenRD.
 * Encapsulate ARM pmap/mmu initialization code from machdep files
   into one common routine.

 Regards,
 Jakub Klama
