Hi Paul, hi everyone,
we had the same problem with our olinuxino-a64, but we were able to solve it by using an old patch series proposed by Icenowy Zheng.
We extended the *.dts with content of the current torvalds/Linux master branch to contain an emac configuration, which basically results in the same changes you did. [0] Additionally We adapted the patch series from [1] for the current v2018.11-rc3 branch of denx/U-Boot. [2] When not applying the patch series, the 'tx-delay-ps' option seems to have no effect on the driver - at least we didn't find reference for this in the code.
After this we are able to use DHCP and boot our board via TFTP.
The patch series is in the state 'Changes Requested' and it seems there was no activity for quite some time. Nonetheless this seems to fix the problem for us. As a side note - this patch series seems also to be necessary for the BananaPi-M3, which uses the same Ethernet driver but a different PHY (Realtek instead of Micrel).
Can you repost the series ?
Best regards
