Their base addresses are floating on highest RAM address. However, they can be disabled in several cases. (1) One specific high memory region is likely to be disabled by code by toggling vms->highmem_{redists, ecam, mmio}. (2) VIRT_HIGH_PCIE_ECAM region is disabled on machine, which is 'virt-2.12' or ealier than it. (3) VIRT_HIGH_PCIE_ECAM region is disabled when firmware is loaded on 32-bits system. (4) One specific high memory region is disabled when it breaks the PA space limit. The current implementation of virt_set_{memmap, high_memmap}() isn't optimized because the high memory region's PA space is always reserved, regardless of whatever the actual state in the corresponding vms->highmem_{redists, ecam, mmio} flag. In the code, 'base' and 'vms->highest_gpa' are always increased for case (1), (2) and (3). It's unnecessary since the assigned PA space for the disabled high memory region won't be used afterwards. Improve the address assignment for those three high memory region by skipping the address assignment for one specific high memory region if it has been disabled in case (1), (2) and (3). The memory layout may be changed after the improvement is applied, which leads to potential migration breakage. So 'vms->highmem_compact' is added to control if the improvement should be applied. For now, 'vms->highmem_compact' is set to false, meaning that we don't have memory layout change until it becomes configurable through property 'compact-highmem' in next patch.

However, the original GICv3 model subtracted off the SGI/PPI. Cosmetically this can be seen at OS boot (Linux) showing 32 shy of what should be there, i.e.: [ 0.000000] GICv3: 224 SPIs implemented Though in hw/arm/virt.c, the machine is configured for 256 SPI's. ARM virt machine likely doesn't have a problem with this because the upper 32 IRQ's don't actually have anything meaningful wired. But, this does become a functional issue on a custom use case which wants to make use of these IRQ's. Additionally, boot code (i.e. TF-A) will only init up to the number (blocks of 32) that it believes to actually be there.

These allow the guest to enable trapping of various EL1 instructions to EL2. In this commit, add the necessary code to allow the guest to set these bits if the feature is present; because the bit is always zero when the feature isn't present we won't need to use explicit feature checks in the "trap on condition" tests in the following commits. Note that although full implementation of the feature (mandatory from Armv8.5 onward) requires all five trap bits, the ID registers permit a value indicating that only TICAB, TOCU and TID4 are implemented, which might be the case for CPUs between Armv8.2 and Armv8.5.

The legacy method doesn't do anything that's invalid in the hold phase, so the conversion is simple and not a behaviour change. Note that we must convert this base class before we can convert the TYPE_ARM_SMMUV3 subclass -- transitional support in Resettable handles "chain to parent class reset" when the base class is 3-phase and the subclass is still using legacy reset, but not the other way around.

To fix it, we can change it to write these values to the dtb using a type width matching #address-cells. This is the intended size for these dtb properties, and is how u-boot, for instance, writes them, although in practice the Linux kernel will cope with them being any width as long as they're big enough to fit the value.

However, since the kvm headers are only optionally used in kvm-constants.h for some sanity checks, we can additionally check the NEED_CPU_H macro first to avoid the poisoned CONFIG_KVM macro, so kvm-constants.h can also be used from "common" files (without the sanity checks - which should be OK since they are still done from other target-specific files instead). This way, and by adjusting some other include statements in the related files here and there, we can move some files from specific_ss into softmmu_ss, so that they only need to be compiled once during the build process.
