u-boot ethernet phy regression on gxbb (nanopi-k2, odroid-c2)

[sarnold]

Describe the bug According to the feedback on this bug: https://github.com/home-assistant/operating-system/issues/1202 ethernet/phy is working at least through 2020.04 u-boot release. Confirmed broken using poky/meta-meson on dunfell branches.

Build Context

• meta-meson dunfell
• meta-meson changes: none prior to reverting u-boot-meson-gx version requirement to 2020.01 (u-boot version on poky dunfell)
• Yocto Project Poky/meta dunfell
• meta-small-arm-extra dunfell
• local.conf normal except for:

PREFERRED_PROVIDER_virtual/kernel ?= "linux-mainline"
PREFERRED_VERSION_linux-mainline ?= "5.10%"
# ethernet bug somewhere after this version
PREFERRED_VERSION_u-boot-meson-gx = "2020.01%"  <= broken without this

Expected behavior Working ethernet.

System (please complete the following information):

• Host OS: gentoo
• Version: N/A
• Architecture: x86_64

Additional context Just building core-image-minimal with some packages, testing on nanopi-k2 and odroid-c2 (confirmed working with u-boot 2020.04 and kernel 5.10.14 with one small espressobin-ultra patch).

Fixed with 1a95da2a8bb9bf268551805655f2a3285243971d (upgrade mainline u-boot to 2020.10) on dunfell
