If you recently followed the instructions to use:

2. https://github.com/raspberrypi/firmware/tree/master/boot/overlays -> overwrite overlays-folder on uSD: 

3. https://github.com/raspberrypi/firmware/tree/master/boot -> copy the following files to uSD: 

instead of what is in sysutils/rpi-firmware and sysutils/u-boot-rpi4
then you likely picked up bad materials.

https://github.com/raspberrypi/firmware/issues

shows people reporting that things quit working for
what appear to be (at times) power problems. This
seems to have been going on for days.

I do not recommend using https://github.com/raspberrypi/firmware/tree/
materials unless you know specific good versions to pick (say
a specific Tag selection).

I also do not recommend copying only some of the files from
https://github.com/raspberrypi/firmware/tree/master/boot/ and mixing
them with files of other vintages. They are not designed to mix and
match arbitrarily as far as I can tell.

I have stuck with sysutils/rpi-firmware and sysutils/u-boot-rpi4 materials
of a fixed vintage. In part is this so that the kernel explorations are
what vary, since -r356767 works and -r356776 does not for the same set
of other materials.

It is already complicated enough trying to find a way to isolate
what is leading to PSCI version 0 instead of 2 based on switching
kernels (and only the kernels).
