With the fixed memor region for gmac spi0 works just fine and i am going to enable it. To enable spi1 i would have to disable uart3 or change the pins - suggestions?
Yes, but not only UART3, UART4 also since SPI1 is using those 4 pins.

Even Mainline doesn't have it yet ...
Patches from Pantelis Antoniou have been submitted several times, first time in 2013, and now after several versions, still not there.
I've personally struggled to get that into Armbian 4.6.2, comparing Raspberry, Beaglebone and CHIP implementations, and pure coincidence, I've finally succeeded yesterday.
Now, time to develop several overlay other the simple tests I did until now.
Maybe I will start some kind of backport into PineA64 later, depending how much code differ ...
