This series adds a new aarch64 machine to QEMU: i.MX 8M Plus EVK [1]. It allows for running Linux distributions such as Buildroot (freescale_imx8mpevk_defconfig) and Arch Linux [2] via direct kernel boot. U-Boot does not work yet. I plan to use this machine myself and I also want to make it available to a bigger audience, so I propose to add it to QEMU. My goal would be to have it added for 10.0.
The series includes the unreviewed patches of [3] and is structured as follows: The first four patches fix some issues in device models reused by the new machine. Patches 5-18 add the machine step by step which includes documentation. Patches 19 and 20 add some further device models that I'd like to use with the new machine. The last patch is a fix I created during debugging but I don't rely on it. I've based some code on existing one (see "Based on" in file headers) and I'm unsure how to handle the licensing and attribution correctly -- advice welcome. The TCA6416 emulation is taken from the Xilinx fork where it is used in some cadence machines. Would the respective upstream maintainers be willing to maintain the device model upstream instead?
