Hello.

On kernel 392b9849c8d147c25557fea5d6dbcddbcb9e72d5 and firmware 7f14c6192dd536392efbad2280e990285447591a,

Adding

[pi5]
force_eeprom_read=0

Makes rpi4 also avoid eeprom read.

Have a good day.

Where the board type is bits 4-11 of the board revision:

pi@raspberrypi:~$ tail -3 /proc/cpuinfo
Revision        : d04170
Serial          : 3c4045e75bb203ac
Model           : Raspberry Pi 5 Model B Rev 1.0

Here the board type (in hexadecimal) is 17, a.k.a. 0x17 or 23.
