Arm

• New Aspeed machines: rainier-bmc and quanta-q7l1-bmc
• Model for Aspeed's Hash and Crypto Engine
• The mps3-an524 board now supports the alternate memory map (via "-machine remap=QSPI")

PowerPC

• With recent enough guests now able to (sometimes) detect hot unplug failures on pseries machine type
• Greatly increased maximum cpu count for pseries; it's now basically arbitrarily high - you will hit KVM or emulation limits before a fixed cut off
• Updated ppce500 firmware image, which should fix pci support
• Added 'pegasos2' machine type emulating the Genesi/bPlan Pegasos II board
• 'mac99' machine now limited to 2GiB of RAM (previously it was allowed on the command line, although it probably wouldn't work properly)

RISC-V

• Clenaup some left over v1.9 code
• Documentation improvements
• Support for the shakti_c machine
• Internal cleanup of the CSR accesses
• Updates to the OpenTitan platform
• Support for the virtio-vga
• Fix for the saturate subtract in vector extensions (https://bugs.launchpad.net/qemu/+bug/1923629)
• Experimental support for the ePMP spec
• A range of other internal code cleanups and bug fixes
