The following systems are involved:
- DB-88F5182
- DB-88F5281
- DB-88F6281
- DB-78100
- SheevaPlug
This overhaul covers the following major changes:
- All integrated peripherals drivers for Marvell ARM SoC, which are
currently in the FreeBSD source tree are reworked and adjusted so they
derive config data out of the device tree blob (instead of hard coded /
tabelarized values).
- Since the common FDT infrastrucutre (fdtbus, simplebus) is used we say
good by to obio / mbus drivers and numerous hard-coded config data.
Note that world needs to be built WITH_FDT for the affected platforms.
