Most important registers are those related to DRAM initialization and calibration, where SPL initiates process and waits until certain bit is set/cleared. This patch adds these registers, initializes reset values from user's guide and updates state of registers as SPL expects it.

Only master-mode functionality is implemented. The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is first part enabling the TWI/I2C bus operation. Since both Allwinner A10 and H3 use the same module, it is added for both boards. Docs are also updated for Cubieboard and Orangepi-PC board to indicate I2C availability.

This is a problem, because at the moment the core memory system does not implement the support for handling unaligned accesses by doing a series of aligned accesses and combining them (system/memory.c:access_with_adjusted_size() has a TODO comment noting this). Fortunately raven_io_read() and raven_io_write() will correctly deal with the case of being passed an unaligned address, so we can fix the missing unaligned access support by setting .impl.unaligned in the MemoryRegionOps struct.

Wire up the IRQ line (this is always safe whether the CPU has the interrupt or not, since it always creates the outbound IRQ line). Report it to the guest via dtb and ACPI if the CPU has the feature. The DTB binding is documented in the kernel's Documentation/devicetree/bindings/timer/arm\,arch_timer.yaml and the ACPI table entries are documented in the ACPI specification version 6.3 or later. Because the IRQ line ACPI binding is new in 6.3, we need to bump the FADT table rev to show that we might be using 6.3 features. Note that exposing this IRQ in the DTB will trigger a bug in EDK2 versions prior to edk2-stable202311, for users who use the virt board with 'virtualization=on' to enable EL2 emulation and are booting an EDK2 guest BIOS, if that EDK2 has assertions enabled. The effect is that EDK2 will assert on bootup: ASSERT [ArmTimerDxe] /home/kraxel/projects/qemu/roms/edk2/ArmVirtPkg/Library/ArmVirtTimerFdtClientLib/ArmVirtTimerFdtClientLib.c(72): PropSize == 36 || PropSize == 48 If you see that assertion you should do one of: * update your EDK2 binaries to edk2-stable202311 or newer * use the 'virt-8.2' versioned machine type * not use 'virtualization=on' (The versions shipped with QEMU itself have the fix.)

QEMU has chosen to UNDEF on all of these. However, for the case of accessing SPSR_hyp from hyp mode, it turns out that real hardware permits this, with the same effect as if the guest had directly written to SPSR. Further, there is some guest code out there that assumes it can do this, because it happens to work on hardware: an example Cortex-R52 startup code fragment uses this, and it got copied into various other places, including Zephyr. Zephyr was fixed to not use this: https://github.com/zephyrproject-rtos/zephyr/issues/47330 but other examples are still out there, like the selftest binary for the MPS3-AN536. For convenience of being able to run guest code, permit this UNPREDICTABLE access instead of UNDEFing it.

Currently we deal with this with a lot of open-coded checks on scc_partno(), but as we add more board types this is getting a bit hard to read. Factor out the conditions into some functions which we can give more descriptive names to.

In many cases we don't really care about the functionality controlled by these registers and a reads-as-written or similar behaviour is sufficient for the moment. For the AN536 the required behaviour is: * A_CFG0 has CPU reset and halt bits - implement as reads-as-written for the moment * A_CFG1 has flash or ATCM address 0 remap handling - QEMU doesn't model this; implement as reads-as-written * A_CFG2 has QSPI select (like AN524) - implemented (no behaviour, as with AN524) * A_CFG3 is MCC_MSB_ADDR "additional MCC addressing bits" - QEMU doesn't care about these, so use the existing RAZ behaviour for convenience * A_CFG4 is board rev (like all other images) - no change needed * A_CFG5 is ACLK frq in hz (like AN524) - implemented as reads-as-written, as for other boards * A_CFG6 is core 0 vector table base address - implemented as reads-as-written for the moment * A_CFG7 is core 1 vector table base address - implemented as reads-as-written for the moment Make the changes necessary for this; leave TODO comments where appropriate to indicate where we might want to come back and implement things like CPU reset. The other aspects of the device specific to this FPGA image (like the values of the board ID and similar registers) will be set via the device's qdev properties.

Unlike the existing FPGA images we already model, this board uses a Cortex-R family CPU, and it does not use any equivalent to the M-profile "Subsystem for Embedded" SoC-equivalent that we model in hw/arm/armsse.c. It's therefore more convenient for us to model it as a completely separate C file. This commit adds the basic skeleton of the board model, and the code to create all the RAM and ROM. We assume that we're probably going to want to add more images in future, so use the same base class/subclass setup that mps2-tz.c uses, even though at the moment there's only a single subclass. Following commits will add the CPUs and the peripherals.
