Thanks for this. Could you squash the commits and check https://meta-raspberrypi.readthedocs.io/en/latest/contributing.html for general contribution guidelines? Do you foresee any impact on non-RPi3+ boards?

When initializing network devices on raspberry pi 3b+ the lan78xx_eth get seq 1. Because of that this network device doesn't get MAC address from BCM2835_MBOX and fail to bind device. To address this issue and don't make much changes in u-boot we can also add MAC address for device of sequence number=1. Signed-off-by: Jakub Szczudlo <[email protected]>

@agherzan commits squashed and commit message updated as in guidelines. I don't see any impact on other raspberries because each one have only one ethernet port. |

Problem accounter when I wanted to use TFTP to send files from server to raspberry. I found some dead links like the ones below:

https://lists.denx.de/pipermail/u-boot/2024-February/546677.html
After some debugging I find the solution. It's easy to understand, don't break things and doesn't modify uboot in big manner
- What I did
Fixes problems with init of ethernet device in uboot
- How I did it
Add default MAC value not only for sequence 0 but also for sequence 1 device.
Also added screenshots
