fix cpu internal ethernet on nanopi-r4se standard version without EEPROM

[jpy794]

Description

Like nanopi-r4s, nanopi-r4se has two variants¹: enterprise and standard version. The difference between the two variants is that the enterprise version has an extra EEPROM to store globally unique MAC address for rk3399's internal ethernet. Currently Armbian r4se device tree is based on r4s-enterprise device tree, which breaks cpu internal ethernet on the standard version due to lack of valid MAC address from EEPROM.

Kernel logs

platform fe300000.ethernet: deferred probe pending: platform: wait for supplier /i2c@ff120000/eeprom@51/mac-address@fa

Since Armbian only maintains image for nanopi-r4s standard version (runs on enterprise board too, just ignoring the unique MAC address), I think it's reasonable to do the same for r4se.

How Has This Been Tested?

Tested on my nanopi-r4se standard version, by installing the dtb package built with ./compile.sh kernel-dtb BOARD=nanopi-r4se BRANCH=edge

Footnotes

1. Although not well documented like r4s, you could see the empty EEPROM paste at the front of r4se board in their wiki. ↩

Thank you! I would propose the same fix for K6.12, which is going to be around for awhile.

Sure, applied to K6.12 too now.
