For running QEMU in system emulation mode, the user needs a rather
strong host system, i.e. not only an embedded low-frequency controller.
All recent beefy arm host machines should support 64-bit now, it's
unlikely that anybody is still seriously using QEMU on a 32-bit arm
CPU, so we deprecate the 32-bit arm hosts here to finally save use
some time and precious CI minutes.

it. Since all recent x86 hardware from the past >10 years is capable of the
64-bit x86 extensions, a corresponding 64-bit OS should be used instead.

+Since QEMU needs a strong host machine for running full system emulation, and
+all recent powerful arm hosts support 64-bit, the QEMU project deprecates the
+support for running any system emulation on 32-bit arm hosts in general. Use
+64-bit arm hosts for system emulation instead. (Note: "user" mode emulation
+continues to be supported on 32-bit arm hosts, too)
