PSU initialization code on zynqmp platforms
Hi Michal,
(Well, that's embarassing. Sending again with a useful subject.)
I'm bringing up u-boot on a custom zynqmp platform. For the PSU initialization, I can start with the psu_init_gpl.[ch] files embedded in the .xsa generated by Vivado. However, these are pretty flawed [1, 2].
What is your workflow for generating and maintaining the in-tree psu_init_gpl files you maintain? Are these files cleaned up and maintained by hand?
If your workflow is functional, I will happily emulate it instead - even if it means straying from Vivado's configuration GUI.
best, Graeme

I am just copy psu init files from xsa and copy it somewhere and then run ./tools/zynqmp_psu_init_minimize.sh to minimize it. And then commit and small manual cleanups to resolved issues reported by checkpatch.
Thanks, Michal

Thanks - that script is exactly what I needed to plug the gap between Vivado and what's in-tree.
