https://github.com/Ansuel/openwrt/commits/main-airoha-6.12/)
* add ethernet switch mdio support from upstream U-Boot
Notable changes:

Notes about en7523 support
--------------------------
This set of patches brings up more or less complete support of EN7523 SoC.
Unfortunately, building of en7523 bootloader will require en7523-bl2.bin
and en7523-bl31.bin blobs which is not available at the moment.
This is the only known blocker for adding en7523 bootloader support.
