From a5cf20d1974f8247ed87fad4a61216cc75eddfdb Mon Sep 17 00:00:00 2001 From: Paul Spooren Date: Mon, 28 Mar 2022 03:29:09 +0100 Subject: build: store sha256_unsigned in JSON Introduce `sha256_unsigned` which is a checksum of the image _before_ a signature is attached. This is helpful to compare image reproducibility. Since the `.sha256sum` file is located in the $(KDIR) folder, switch $(BIN_DIR) with $(KDIR) to simplify the code. The value of $(BIN_DIR) itself is not stored inside the resulting JSON file, so it can be replaced.
