Subject: [PATCH v3 3/3] Makefile/coreboot use SOURCE_DATE_EPOCH as time source if set
Date: Fri, 4 Dec 2015 19:32:22 +0100 [thread overview]
Message-ID: <1449253942-29510-4-git-send-email-lynxis@fe80.eu> (raw)
In-Reply-To: <1449253942-29510-1-git-send-email-lynxis@fe80.eu>
In-Reply-To: <1449245444-17579-1-git-send-email-lynxis@fe80.eu>
mkstandalone sets timestamps for files which can be overriden by a fixed_timestamp.
This makes it possible to build reproducible builds for coreboot.
To build a reproducible build of grub for coreboot do:
export SOURCE_DATE_EPOCH=1134242
make default_payload.elf
