Further trying to boot git://github.com/riscv/riscv-linux#riscv-linux-4.18 on
the HiFive-U I can't seem to find the necessary bits to drive the MMC
interface. Any pointers?
Andreas.

I have now found the missing drivers and pushed the result to
git://github.com/andreas-schwab/riscv-linux#riscv-linux-4.18

Paul is probably the best bet here, as he's working through our mess of
out-of-tree drivers. If you want to do it yourself then you'll have to
forward-port the SPI driver from riscv-linux-4.15 (or wip-spi), fix the bugs,
and then port the dependent drivers.
Sorry!

At least on top of 4.17 it works pretty well (see
git://github.com/andreas-schwab/riscv-linux#riscv-4.17), but the same
drivers on top of 4.18 are very unstable.

There were some network and DMA32 issues in 4.18. Here is my tree on top
of 4.19-rc2. I use this for booting Fedora Gnome Desktop as well.
