[DMA Engine Framework] status report #3

[Jakub Klama]

Done this week:
* Completed milestone M1 (established required APIs)
* Published some info about DMA APIs on wiki - 
  see http://wiki.freebsd.org/SOC2010JakubKlama
* Done research about configuring DMA channel allocations for various
  kernel subsystems (for now, it will be hardcoded in kernel, but easy 
  to refactor when FDT on this platform became available)
* Added error handling in EDMA3 driver

Plans for next week:
* Finish EDMA3 driver
* Test transfers in userspace using char device driver
* Do some research about using DMA in kernel memcpy() and bzero()
* Clean up existing code
