| H A D | pnv_xscom.c | 70c059e9 Fri Dec 13 12:00:35 GMT 2019 Greg Kurz <groug@kaod.org> ppc/pnv: Introduce PnvChipClass::xscom_pcba() method
The XSCOM bus is implemented with a QOM interface, which is mostly
generic from a CPU type standpoint, except for the computation of
addresses on the Pervasive Connect Bus (PCB) network. This is handled
by the pnv_xscom_pcba() function with a switch statement based on
the chip_type class level attribute of the CPU chip.
This can be achieved using QOM. Also the address argument is masked with
PNV_XSCOM_SIZE - 1, which is for POWER8 only. Addresses may have different
sizes with other CPU types. Have each CPU chip type handle the appropriate
computation with a QOM xscom_pcba() method.
