The current build system embeds the EFI Signature List(ESL) into the dtb to be used in the EFI capsule authentication. This ESL file is specified through the CONFIG_EFI_CAPSULE_ESL_FILE Kconfig option. If CONFIG_EFI_CAPSULE_ESL_FILE is not specified, U-boot build ends up with failure but the cause of failure is not easily understandable. Current error message is as follows.
FATAL ERROR: Error reading file into data: Is a directoryCheck /home/ubuntu/src/ledge/u-boot/arch/arm/dts/.synquacer-sc2a11-developerbox.dtb.pre.tmp for errors make[2]: *** [scripts/Makefile.lib:355: arch/arm/dts/synquacer-sc2a11-developerbox.dtb] Error 1 make[1]: *** [dts/Makefile:44: arch-dtbs] Error 2 make: *** [Makefile:1165: dts/dt.dtb] Error 2 make: *** Waiting for unfinished jobs....
This commit shows the error message that CONFIG_EFI_CAPSULE_ESL_FILE must be specified when the EFI capsule authentication is enabled, then terminate the build with error.
