From: Simon Glass <sjg@chromium.org> The ARM EFI app does not successfully boot an OS at present. This series includes patches to allow it to boot an OS via extlinux: The main changes are: - Call exit-boot-services before jumping to the OS - Write the physical-memory info to the FDT - Tidy up some Kconfig options - Improve keyboard compatibility Note that QEMU 8.2 does not boot Ubuntu 24.04 with this series[1]. The kernel dies quite early with: ERROR:target/arm/internals.h:767:regime_is_user: code should not be reached Bail out! ERROR:target/arm/internals.h:767:regime_is_user: code should not be reached QEMU 9.2 resolves this problem.
