2022-10-17ppc440_uc.c: Move some macros to ppc4xx.hBALATON Zoltan
These are used by both the SDRAM controller model and system DCRs. In preparation to move SDRAM controller in its own file move these macros to the ppc4xx.h header.

2022-10-17ppc440_sdram: QOM'ifyBALATON Zoltan
Change the ppc440_sdram model to a QOM class derived from the PPC4xx-dcr-device and name it ppc4xx-sdram-ddr2. This is mostly modelling the DDR2 SDRAM controller found in the 460EX (used on the sam460ex board). Newer SoCs (regardless of their PPC core, e.g. 405EX) may have this controller but we only emulate enough of it for the sam460ex u-boot firmware.

Move the check for valid memory sizes from board to sdram controller init.

2022-10-17ppc4xx_sdram: QOM'ifyBALATON Zoltan
Change the ppc4xx_sdram model to a QOM class derived from the PPC4xx-dcr-device and name it ppc4xx-sdram-ddr. This is mostly modelling the DDR SDRAM controller found in the 440EP (used on the bamboo board) but also backward compatible with the older DDR controllers on some 405 SoCs so we also use it for those now. This likely does not cause problems for guests we run as the new features are just not accessed but to model 405 SoC accurately some features may have to be disabled or the model split between 440 and older. Newer SoCs (regardless of their PPC core, e.g. 405EX) may have an updated DDR2 SDRAM controller implemented by the ppc440_sdram model (only partially, enough for the 460EX on the sam460ex) that is not yet QOM'ified in this patch. That is intended to become ppc4xx-sdram-ddr2 when QOM'ified later.

2022-08-31ppc/ppc4xx: Introduce a DCR device modelCédric Le Goater
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/ppc405: QOM'ify CPUCédric Le Goater
Drop the use of ppc4xx_init() and duplicate a bit of code related to clocks in the SoC realize routine. We will clean that up in the following patches. ppc_dcr_init() simply allocates default DCR handlers for the CPU. Maybe this could be done in model initializer of the CPU families needing it.

It is an initial model to start QOMification of the PPC405 board. QOM'ified devices will be reintroduced one by one. Start with the memory regions, which name prefix is changed to "ppc405". Also, initialize only one RAM bank. The second bank is a dummy one (zero size) which is here to match the hard coded number of banks in ppc405ep_init().
