From 6dfd14e1228e6e14462f377987bc896d6b7f1dd5 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 3 Sep 2025 00:01:55 +0200 Subject: mkimage: Add support for bundling TFA BL31 in mkimage -f auto Introduce two new parameters to be used with mkimage -f auto to bundle TFA BL31 image into fitImage, using auto-generated fitImage. Add -y to specify TFA BL31 file name and -Y to specify TFA BL31 load and entry point address. This is meant to be used with systems which boot all of TFA BL31, Linux and its DT from a single fitImage, all booted by U-Boot. Example invocation: " $ mkimage -E -A arm64 -C none -e 0x50200000 -a 0x50200000 -f auto \ -d arch/arm64/boot/Image \ -b arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk.dtb \ -y ../tfa/build/rcar_gen4/release/bl31.bin -Y 0x46400000 \ /path/to/output/fitImage " Documentation update and test are also included, the test validates both positive and negative test cases, where fitImage does not include TFA BL31 and does include TFA BL31 blobs.
