This patchset is really a roll-up/rework of ESCC patches posted by Hervé and John along with a general tidy-up of the ESCC channel code and addition of DBDMA properties.
The most interesting change with this patchset is that a basic OS 9.2 image with just OT extensions enabled now hangs in QEMU in a loop constantly polling ESCC registers rather than crashing into MacsBug.
NOTE: for OS 9 testers, QEMU's default G4 CPU for mac99 seems buggy and always crashes into MacsBug. Make sure that you have the interpreter.fs patch applied and run QEMU with -cpu G3.
