The following systems are affected:
- MPC8555CDS
- MPC8572DS
This overhaul covers the following major changes:
- All integrated peripherals drivers for Freescale MPC85XX 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).
- This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC,
QUICC, UART, CFI.
- Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire
ocpbus(4) driver, which was based on hard-coded config data.
Note that world for these platforms has to be built WITH_FDT.
