Cédric Le Goater	23a782eb66	ppc/pnv: change the PowerNV machine devices to be non user creatable The PowerNV machine emulates an OpenPOWER system and the PowerNV chip devices are models of the internal logic of the POWER processor. They can not be instantiated by the user on the QEMU command line. The PHB3/PHB4 devices could be an exception in the future after some rework on how the device tree is built. For the moment, exclude them also.

Cédric Le Goater	8f09231631	ppc/pnv: Introduce PBA registers The PBA bridge unit (Power Bus Access) connects the OCC (On Chip Controller) to the Power bus and System Memory. The PBA is used to gather sensor data, for power management, for sleep states, for initial boot, among other things. The PBA logic provides a set of four registers PowerBus Access Base Address Registers (PBABAR0..3) which map the OCC address space to the PowerBus space. These registers are setup by the initial FW and define the PowerBus Range of system memory that can be accessed by PBA. The current modeling of the PBABAR registers is done under the common XSCOM handlers. We introduce a specific XSCOM regions for these registers and fix : - BAR sizes and BAR masks - The mapping of the OCC common area. It is common to all chips and should be mapped once. We will address per-OCC area in the next change. - OCC common area is in BAR 3 on P8 Inspired by previous work of Balamuruhan S <bala24@linux.ibm.com> Signed-off-by: Cédric Le Goater <clg@kaod.org> Message-Id: <20191211082912.2625-2-clg@kaod.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>	7 years ago
Greg Kurz	f2582acf99	ppc/pnv: Link "chip" property to PnvHomer::chip pointer The homer object has both a pointer and a "chip" property pointing to the chip object. Confusing bugs could arise if these ever go out of sync. Change the property definition so that it explicitely sets the pointer.
