Make DMA bottom-half driven (v2)

The current DMA routines are driven by a call in main_loop_wait() after every
select.

This patch converts the DMA code to be driven by a constantly rescheduled
bottom half. The advantage of using a scheduled bottom half is that we can...

ETRAX-FS: Add support for DMA channel resets, needed for recent linux kernels.

  • Correct numeric value for the RST state.
  • Add emulation for reseting a DMA channel.
  • Add a few sanity checks.
  • Make it compile with debug enabled.

Avoid refering to CRIS specific cpu-state to be able to use these blocks with other cores.

ETRAX: More DMA context level related fixes.

  • When hitting EOL (end of list) at the data descriptor level, the DMA should mark the current context-descriptor as disabled and perform a context-store so software can see whats goin on.
  • Context loads update RW_SAVED_DATA_BUF, data loads dont. This fixes an issue with ethernet bootstrapping....

  • Move DMA_run into the dma controller to allow for multiple ETRAX/CRIS machines.
  • Support both ELF and kimage kernel images.
  • Correct emulation of the DMA RW_DATA register.
