Hi,
I was able to compile upstream kernel for orange pi h3 with ethernet patches from https://github.com/montjoie/linux/tree/sun8i-emac-wip (patches were applied without any issues). Board successfuly starts, ethernet works, dmesg reports some errors . All changes can be found at https://github.com/balldir/lib/tree/h3_mainline_upstream. Is there any list of tests to check "build acceptance" ? I need spi and i2c working for my project, so I will be grateful if someone points me out to avaliable patches for spi and i2c (I saw few in https://groups.google.com/forum/#!forum/linux-sunxi , but haven't tested them yet).
