From ef3f08ae78a0cbcf9dc25ab7c7cbe4bbaf41db8f Mon Sep 17 00:00:00 2001 From: Aswin Murugan Date: Tue, 24 Mar 2026 23:29:12 +0530 Subject: efi_loader: make EFI_HAVE_RUNTIME_RESET a user-selectable option Expose EFI_HAVE_RUNTIME_RESET as a proper Kconfig boolean with a prompt so platforms can explicitly enable or disable advertising the EFI reset runtime service. The current PSCI-based EFI runtime reset implementation is always enabled whenever CONFIG_PSCI_RESET is selected, but it does not support passing the additional arguments required for specialized reset modes. As a result, reboot requests such as bootloader mode or EDL mode cannot be propagated correctly and instead fall back to a normal reboot. By making EFI_HAVE_RUNTIME_RESET user-configurable, platforms that depend on extended PSCI reset can now explicitly disable EFI runtime reset handling even when CONFIG_PSCI_RESET is enabled, ensuring that the kernel retains full control of advanced reboot paths. Default behavior for existing platforms remains unchanged.
