Subject: [PATCH] configs: qcom_defconfig: Enable EFI variable runtime storage
Date: Mon, 20 Jul 2026 15:55:52 +0530	[thread overview]
Message-ID: <20260720-runtime-v1-1-7f904b4cb3ed@oss.qualcomm.com> (raw)

Allow SetVariable at runtime on U-Boot's in-RAM EFI variable
store so the OS can write EFI variables via efivarfs. With this
enabled U-Boot also advertises EFI_RT_SUPPORTED_SET_VARIABLE and
exposes the RTStorageVolatile and VarToFile variables, which
userspace tools such as efivar use to persist runtime changes
back to the ubootefi.var store on the ESP across reboots.

EFI_RT_VOLATILE_STORE depends on EFI_VARIABLE_FILE_STORE; select
it explicitly so the option is not silently dropped if that
default changes.
