EFI_HAVE_RUNTIME_RESET is now a proper Kconfig configurable option\n This allows individual platforms, such as Qualcomm boards, to \n explicitly disable U-Boot’s EFI runtime reset callbacks when required.\n\n2. The Qualcomm defconfig disables EFI_HAVE_RUNTIME_RESET so that the\n kernel can manage advanced reboot flows (EDL, bootloader entry, etc.)\n without U-Boot overriding those reset modes through EFI runtime\n services.\n\n3. The EFI runtime table is updated accordingly to conditionally\n advertise reset support only when EFI_HAVE_RUNTIME_RESET is enabled.\n\nThese changes maintain existing default behavior for platforms that rely\non U-Boot’s EFI reset services, while enabling platforms with more\ncomplex reboot semantics to opt out cleanly.\n\n[1] https://lore.kernel.org/all/CAC_iWjKZXsE86J_wJ=JTE0TGL=MqGm8YRYsq4BrkU2ba3me6OQ@mail.gmail.com/\n\nSigned-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>\n---\nChanges in v4:\n- Made EFI_HAVE_RUNTIME_RESET user configurable & used it to disable U-Boot’s EFI runtime reset\n for qualcomm platforms\n- Link to v3: https://lore.kernel.org/all/20260213110527.1254098-1-aswin.murugan@oss.qualcomm.com/\n\nChanges in v3:\n- Updated the commit message\n- Changed 'CONFIG_EFI_PSCI_RESET_RUNTIME=n' to '# CONFIG_EFI_PSCI_RESET_RUNTIME is not set'\n- Link to v2: https://lore.kernel.org/all/20260114111624.2321852-1-aswin.murugan@oss.qualcomm.com/\n\nChanges in v2:\n- As per review comments made default y for EFI_PSCI_RESET_RUNTIME config\n- Disabled the EFI_PSCI_RESET_RUNTIME config for qualcomm platforms\n- Link to v1: https://lore.kernel.org/all/20260108105146.1285450-1-aswin.murugan@oss.qualcomm.com/\n---\nAswin Murugan (2):\n efi_loader: make EFI_HAVE_RUNTIME_RESET a user-selectable option\n qcom_defconfig: Disable EFI_HAVE_RUNTIME_RESET in qcom_defconfig\n\n configs/qcom_defconfig | 1 +\n lib/efi_loader/Kconfig | 3 +--\n 2 files changed, 2 insertions(+), 2 deletions(-)" }
