[OpenBIOS] [PATCH 0/6] ppc: ESCC fixups (MacOS related)

[Mark Cave-Ayland]

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.

There are still some issues accessing the serial ports in BSD/Linux but fortunately
no regressions/hangs show in testing here with this patchset applied.

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.
