If you have a number of RPI's = that netboot, the way that the common config.txt is segmented for each boar= d is by using the '[serial number in hex]' section headers. Unfortu= nately, netboot also requires changing the BOOT_ORDER parameter in EEPROM, = which requires access to /dev/mmcblk* and some way of generating the proper= .bin format. So Linux is still needed for the initial setup.

I've done that. Sorry for letting it get out of sync with the kernel so= urce.

The new contrib/miller/9pi.img.gz has
- the latest firmware files from the raspberry pi github
- the update to initialise xhci firmware for pi400 and recent pi4 boards - a tweak to the pi4 gigabit ethernet driver to allow jumbo packets
- a new /dev/serial device from which you can read the board serial number = (I forget why)

Nothing outside the kernel has changed from the previous image.
