The limit was decided based on how known platform boot plus some slack. We had a recent report that this is not sufficient on the AVA platform with a old firmware [1]. But the restriction is not going to change in Xen 4.18. So document the limit clearly in docs/misc/arm/booting.txt I forgot to add a link to [1] 20231013122658.1270506-3-leo.yan@xxxxxxxxxx Cheers, -- Julien Grall
