2023-06-23target/arm: Add cpu properties for enabling FEAT_RMERichard Henderson
Add an x-rme cpu property to enable FEAT_RME. Add an x-l0gptsz property to set GPCCR_EL3.L0GPTSZ, for testing various possible configurations. We're not currently completely sure whether FEAT_RME will be OK to enable purely as a CPU-level property, or if it will need board co-operation, so we're making these experimental x- properties, so that the people developing the system level software for RME can try to start using this and let us know how it goes. The command line syntax for enabling this will change in future, without backwards-compatibility.

2023-06-23target/arm: Handle Block and Page bits for security spaceRichard Henderson
With Realm security state, bit 55 of a block or page descriptor during the stage2 walk becomes the NS bit; during the stage1 walk the bit 5 NS bit is RES0. With Root security state, bit 11 of the block or page descriptor during the stage1 walk becomes the NSE bit. Rather than collecting an NS bit and applying it later, compute the output pa space from the input pa space and unconditionally assign. This means that we no longer need to adjust the output space earlier for the NSTable bit.

2023-06-22mac_via: fix rtc command decoding for the PRAM seconds registersMark Cave-Ayland
Analysis of the MacOS toolbox ROM code shows that on startup it attempts 2 separate reads of the seconds registers with commands 0x9d...0x91 followed by 0x8d..0x81 without resetting the command to its initial value. The PRAM seconds value is only accepted when the values of the 2 separate reads match. From this we conclude that bit 4 of the rtc command is not decoded or we don't care about its value when reading the PRAM seconds registers. Implement this decoding change so that both reads return successfully which allows the MacOS toolbox ROM to correctly set the date/time.

2023-06-22q800: reimplement mac-io region aliasing using IO memory regionMark Cave-Ayland
The current use of aliased memory regions causes us 2 problems: firstly the output of "info qom-tree" is absolutely huge and difficult to read, and secondly we have already reached the internal limit for memory regions as adding any new memory region into the mac-io region causes QEMU to assert with "phys_section_add: Assertion `map->sections_nb < TARGET_PAGE_SIZE' failed". Implement the mac-io region aliasing using a single IO memory region that applies IO_SLICE_MASK representing the maximum size of the aliased region and then forwarding the access to the existing mac-io memory region using the address space API.

2023-06-21target/tricore: Fix ICR.IE offset in RESTORE insnBastian Koppelmann
from ISA v1.6.1 onwards the bit position of ICR.IE changed. ctx->icr_ie_offset contains the correct value for the ISA version used by the vCPU. We also need to exit this tb here, as we might have enabled interrupts.

2023-06-21target/tricore: Honour privilege changes on PSW writeBastian Koppelmann
the CPU can change the privilege level by writing the corresponding bits in PSW. If this happens all instructions after this 'mtcr' in the TB are translated with the wrong privilege level. So we have to exit to the cpu_loop() and start translating again with the new privilege level.
