Hi Matthias,
yes, i network boot with the beta firmware, since a while.
Short Steps:
* take latest bootloader from ( github.com/raspberrypi/firmware/boot/ )
* patched the beta pieeprom & vl805 with the recovery.bin and bootconf.txt
- ( github.com/raspberrypi/rpi-eeprom/boot/ )
* in bootconf.txt inside pieeprom i used BOOT_ORDER=0x12 - so that network
boot was at first. (
https://github.com/raspberrypi/rpi-eeprom/blob/master/firmware/raspberry_pi4_network_boot_beta.md
)
Yesterday i figured out, that it was possible to embed the initramfs into
the kernel. Today i will try this, because my distribution has NFS as
module for the root filesystem.
Would be nice if the rpi4 would accept the ramfsfile from the config.txt to
load the initrd from tftp .. ;-)
i tried to add some more nic-id's inside broadcom.c, but with no success:
( https://github.com/sd-hd/u-boot/blob/rpi4/drivers/net/phy/broadcom.c )
The 64bit armstub with network enabled inside the assembler, seems to have
no affect inside config.txt. (
https://github.com/raspberrypi/tools/blob/master/armstubs/armstub8.S )
My experimental u-boot devicetree prints this below, but i don't know how
to enable the devices under the "scb - simple bus"...
Maybe i can help testing for you ?
