-we will wait till phy driver is in linux mainline and use this as base for rewriting uboot driver
+This is fixed in my 2024-04 uboot by always run autonegotiation code (genphy code seems not working here).
+Writing firmware to emmc boot1:
+<code>
+usb start
+mmc partconf 0 1 2 2
+mmc erase 0x0 0x120
+load usb 0:1 $loadaddr EthMD32.dm.bin
+mmc write $loadaddr 0x0 0x20
+load usb 0:1 $loadaddr EthMD32.DSP.bin
+mmc write $loadaddr 0x20 0x100
+mmc partconf 0 1 1 0
