This is better than v4, and on the hardware platforms I could build and boot on (which was most of mine except the am62x_beagleplay), the tests ran and completed, including the tftp+boot a Linux kernel. The bad news is CI blows up, a lot: https://source.denx.de/u-boot/u-boot/-/pipelines/21764 And: https://dev.azure.com/u-boot/a1096300-2999-4ec4-a21a-4c22075e3771/_apis/build/builds/9014/logs/106 which is another Kconfig dependency problem. I don't _think_ I introduced that, but since this wasn't against top of tree, I had to apply the cmd/Kconfig patch manually. I have my world build running still and may have more comments based on that. -- Tom
