Might have been fixed by QEMU commit 61b82973e in 2022, which says # This change fixes in passing booting on the 'midway' board model, # which has been completely broken since we added support for Hyp # mode to the Cortex-A15 CPU > I only test highbank manually (not in automated tests).

I don't think these machine types provide anything to users that is particularly interesting (if you just want "boot an A15 or A9 Linux" then the virt board will do fine, and the original "test system software for this hardware" use case is long dead). So I'm in favour of deprecating these (and eventually dropping them). There's not actually a lot of highbank/midway specific code here (no complex SoC modelling, lots of stock Arm peripheral devices, so just 400 lines in hw/arm/highbank.c, plus another 450 in hw/net/xgmac.c for the ethernet controller), but if nobody's using it then there's no point keeping it around. thanks -- PMM
