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.
Do you know which ESCC register that Mac OS 9 is polling? If you do then making a patch that changes the value of this register to something Mac OS 9 expects can be done.
