Yes, cold boot crashes after loading the kernel in pmapboot_protect()
when accessing the mmu tables. Maybe some stale TLB entry.

That part is fine, only function 1 attaches (and implicitely uses the other
functions).

You need the files for bcm43455.

I also see some sdhc0 errors, but not in this place. Maybe wrong firmware
files ?

The txt file is for pi3b+ which uses the same chip.

That's just the same as above. The firmware is written in 64 byte chunks.
