$ mkimage -f fit-image.its /work/Xrouter/staging/ipq4018/image/ipq4018.itb
fit-image.its:48.12-53.5: Warning (unit_address_vs_reg): /configurations/config@1: node has a unit name, but no reg or ranges property
mkimage: verify_header failed for FIT Image support with exit code 1
查找网上的原因是，its文件中，名字里面含有@。新版本的mkimage不支持。把@改成-就可以了。

commit 822564cd3aa1a6a092cc227e394f31f902864b88 Author: Nathan Chancellor <nathan@kernel.org> Date: Fri Apr 9 12:21:28 2021 -0700 MIPS: generic: Update node names to avoid unit addresses commit e607ff630c6053ecc67502677c0e50053d7892d4 upstream. With the latest mkimage from U-Boot 2021.04, the generic defconfigs no longer build, failing with: /usr/bin/mkimage: verify_header failed for FIT Image support with exit code 1 This is expected after the linked U-Boot commits because '@' is forbidden in the node names due to the way that libfdt treats nodes with the same prefix but different unit addresses. Switch the '@' in the node name to '-'. Drop the unit addresses from the hash and kernel child nodes because there is only one node so they do not need to have a number to differentiate them.
