From: Patrick Rudolph Date: Wed, 23 Oct 2024 13:20:17 +0000 (+0200) Subject: arm: mach-bcm283x: Enable ARMV8_MULTIENTRY X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=3cc4123ed50b1b6d2ddaf1886dd70d7b8bf8b6a6;p=u-boot.git 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.
