So, next up is fixing this in CI. After taking Andrew's patch to fix the
typedef issue, and after my patches to ensure we can get
pyyaml/jsonschema for python, there's problems still:
Over at https://source.denx.de/u-boot/u-boot/-/jobs/617966:
binman: Filename 'spl/dts/k3-am68-sk-base-board.dtb' not found in input
path (.,/builds/u-boot/u-boot,board/ti/j721s2,arch/arm/dts)
(cwd='/tmp/.bm-work/j721s2_hs_evm_a72')

And then:
https://source.denx.de/u-boot/u-boot/-/jobs/617965#L1328
Error: arch/arm/dts/k3-am62a-sk-binman.dtsi:167.1-8 syntax error
