Thanks for the contribution!

I believe you need to update the K230 documentation. If peripheral modeling
for things like UNGIP and GSDMA has been added, could the boot flow in the
firmware linux booting path be simplified to better align with the hardware's
actual boot process?

cc Junze, Can you help review this? Thanks!


Thanks,
Chao
