Hi!
Recently I've upgraded a video core firmware on my RPi4 and I've noticed that u-boot in ARM 32bit mode stopped working properly or even randomly crashes. I've bisected the firmware releases and the issue appears for the first time in the commit 63b1922311 ("firmware: arm_loader: Update armstubs with those from PR 117 See: https://github.com/raspberrypi/tools/pull/117").
Just for confirmation,
This issue can be easily observed as a failure of the xhci. See the attached log:

Can you try with today's master branch, I'm specially interested in seeing if 56f1bcc4b7fb helps.

Is it a known issue? In ARM64 mode everything works fine, but this not very surprising, because the firmware change in the mentioned commit is related to the ARM 32bit mode. Does anyone have an idea how to fix this issue? I've checked also the latest version of the RPi firmware, but the issue is still there.
Best regards
