RPI CM5 has 130s delay on boot

[andrew at race-technology.com]

Hello all,

 

I'm feeling a bit out my depth and hoping someone can help me. We've been
using uboot on the RPI CM4 with great success, it's been perfect.

 

We are migrating some projects to the RPI CM5 but have hit a roadblock. The
boot process regularly (but not always) gets stuck for exactly 130s, as
shown here:

After searching, this appears to be the same issue as reported here:
