2022-08-31ppc/ppc4xx: Introduce a DCR device modelCédric Le Goater1-0/+41
The Device Control Registers (DCR) of on-SoC devices are accessed by software through the use of the mtdcr and mfdcr instructions. These are converted in transactions on a side band bus, the DCR bus, which connects the on-SoC devices to the CPU. Ideally, we should model these accesses with a DCR namespace and DCR memory regions but today the DCR handlers are installed in a DCR table under the CPU. Instead, introduce a little device model wrapper to hold a CPU link and handle registration of DCR handlers. The DCR device inherits from SysBus because most of these devices also have MMIO regions and/or IRQs. Being a SysBusDevice makes things easier to install the device model in the overall SoC.

2022-08-31ppc/pnv: add PHB4 helpers for user created pnv-phbDaniel Henrique Barboza1-3/+32
The PHB4 backend relies on a link with the corresponding PEC element. This is trivial to do during machine_init() time for default devices, but not so much for user created ones. pnv_phb4_get_pec() is a small variation of the function that was reverted by commit 9c10d86fee "ppc/pnv: Remove user-created PHB{3,4,5} devices". We'll use it to determine the appropriate PEC for a given user created pnv-phb that uses a PHB4 backend. This is done during realize() time, in pnv_phb_user_device_init().

2022-08-31ppc/pnv: turn chip8->phbs[] into a PnvPHB* arrayDaniel Henrique Barboza1-5/+22
When enabling user created PHBs (a change reverted by commit 9c10d86fee) we were handling PHBs created by default versus by the user in different manners. The only difference between these PHBs is that one will have a valid phb3->chip that is assigned during pnv_chip_power8_realize(), while the user created needs to search which chip it belongs to. Aside from that there shouldn't be any difference. Making the default PHBs behave in line with the user created ones will make it easier to re-introduce them later on. It will also make the code easier to follow since we are dealing with them in equal manner. The first step is to turn chip8->phbs[] into a PnvPHB3 pointer array. This will allow us to assign user created PHBs into it later on. The way we initilize the default case is now more in line with that would happen with the user created case: the object is created, parented by the chip because pnv_xscom_dt() relies on it, and then assigned to the array.

2022-08-31ppc/pnv: add helpers for pnv-phb user devicesDaniel Henrique Barboza1-0/+20
pnv_parent_qom_fixup() and pnv_parent_bus_fixup() are versions of the helpers that were reverted by commit 9c10d86fee "ppc/pnv: Remove user-created PHB{3,4,5} devices". They are needed to amend the QOM and bus hierarchies of user created pnv-phbs, matching them with default pnv-phbs. A new helper pnv_phb_user_device_init() is created to handle user-created devices setup. We're going to call it inside pnv_phb_realize() in case we're realizing an user created device. This will centralize all user device realated in a single spot, leaving the realize functions of the phb3/phb4 backends untouched. Another helper called pnv_chip_add_phb() was added to handle the particularities of each chip version when adding a new PHB.

2022-08-31ppc/pnv: turn PnvPHB4 into a PnvPHB backendDaniel Henrique Barboza1-3/+17
Change the parent type of the PnvPHB4 device to TYPE_PARENT since the PCI bus is going to be initialized by the PnvPHB parent. Functions that needs to access the bus via a PnvPHB4 object can do so via the phb4->phb_base pointer. pnv_phb4_pec now creates a PnvPHB object. The powernv9 machine class will create PnvPHB devices with version '4'. powernv10 will create using version '5'. Both are using global machine properties in their class_init() to do that. These changes will benefit us when adding PnvPHB user creatable devices for powernv9 and powernv10.

2022-08-31ppc/pnv: turn PnvPHB3 into a PnvPHB backendDaniel Henrique Barboza1-6/+15
We need a handful of changes that needs to be done in a single swoop to turn PnvPHB3 into a PnvPHB backend. In the PnvPHB3, since the PnvPHB device implements PCIExpressHost and will hold the PCI bus, change PnvPHB3 parent to TYPE_DEVICE. There are a couple of instances in pnv_phb3.c that needs to access the PCI bus, so a phb_base pointer is added to allow access to the parent PnvPHB. The PnvPHB3 root port will now be connected to a PnvPHB object. In pnv.c, the powernv8 machine chip8 will now hold an array of PnvPHB objects. pnv_get_phb3_child() needs to be adapted to return the PnvPHB3 backend from the PnvPHB child. A global property is added in pnv_machine_power8_class_init() to ensure that all PnvPHBs are created with phb->version = 3. After all these changes we're still able to boot a powernv8 machine with default settings. The real gain will come with user created PnvPHB devices, coming up next.

2022-08-31ppc/pnv: Add initial P9/10 SBE modelNicholas Piggin5-0/+454
The SBE (Self Boot Engine) are on-chip microcontrollers that perform early boot steps, as well as provide some runtime facilities (e.g., timer, secure register access, MPIPL). The latter facilities are accessed mostly via a message system called SBEFIFO. This driver provides initial emulation for the SBE runtime registers and a very basic SBEFIFO implementation that provides the timer command. This covers the basic SBE behaviour expected by skiboot when booting.
