From 3cc4123ed50b1b6d2ddaf1886dd70d7b8bf8b6a6 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Wed, 23 Oct 2024 15:20:17 +0200 Subject: [PATCH] arm: mach-bcm283x: Enable ARMV8_MULTIENTRY On FDT platforms the APs are brought out of reset using the spin-table as defined in the DT. On ACPI enabled platforms there's no FDT, thus enable the ARMV8_MULTIENTRY and BLOBLIST to use the ACPI parking protocol instead. TEST: - APs enter Linux when run on qemu-system-aarch64 -machine raspi4b - APs on real hardware do not enter Linux, but continue spinning in their ACPI parking protocol spinloop. To be investigated.
