From 2eb8cd5bd4936a5eb2e77729855d946f6720921c Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Fri, 1 Nov 2024 10:17:57 +0100 Subject: [PATCH] arm64: zynqmp: Add binman description for SOM There is necessary to do some steps to compose boot images. These steps were in scripts in layers for a while. That's why introduce description via binman to simplify wiring and remove all scripting around. This should make sure that everybody is up2date with the latest versions. The first step is to create fit image with DTBs with descriptions in configuration node which is written as regular expression to match all SOM versions. Description is there for k24 and k26 in spite of low level psu_init configuration is different. The reason is that it goes to u-boot.itb image which is the same for k24 and k26. u-boot.itb is another image which is generated. It is normally generated via arch/arm/mach-zynqmp/mkimage_fit_atf.sh but this script is supposed to be deprecated. FIT image by purpose is using 64bit addresses to have default option to move images to high DDR (above 4GB). TF-A and TEE are optional components but in the most cases TF-A is present all the time and TEE(OP-TEE) is used by some configurations too. 3rd generated image is boot.bin with updated user field which contains version number. This image can be used with updated Image Selector which supports A/B update mechanisms with rollback protection. 4th image is image.bin which binary file which contains boot.bin and u-boot.itb together and can be programmed via origin Image Selector. This image can be also used for creating one capsule which contains both boot images (in SPL boot flow).
