The file u-boot-aptiv-cvc-sousa.tar.gz is the U-Boot source code. It's based on NXP Auto Linux BSP(auto_yocto_bsp) release/bsp29.0 with patches meta-uboot-patches-aptiv-cvc-sousa added.
The file meta-uboot-patches-aptiv-cvc-sousa.tar.gz is a Yocto layer used to patch U-Boot. You can use it to rebuild U-Boot.
To rebuild U-Boot you need to have repo installed on Linux and its prerequisites.
Running the below command would be enough to completely build U-Boot to be deployed.
$ mkdir fsl-auto-yocto-bsp
$ tar -xvf meta-uboot-patches-aptiv-cvc-sousa.tar.gz -C fsl-auto-yocto-bsp
$ cd fsl-auto-yocto-bsp
$ repo init -u https://source.codeaurora.org/external/autobsps32/auto_yocto_bsp -b release/bsp29.0
$ repo sync
$ ./sources/meta-alb/scripts/host-prepare.sh
$ source nxp-setup-alb.sh -m s32g274aevb
$ bitbake-layers add-layer ../meta-uboot-patches-aptiv-cvc-sousa
$ bitbake u-boot
The built image can be found in build_s32g274aevb/tmp/deploy/images/s32g274aevb.
The file u-boot-sdcard-2020.04-r0.s32 is the produced U-Boot image. It can be renamed to u-boot-aptiv_cvc_sousa.s32-sdcard.
