Hi Icenowy,
Currently D$ support of SUNIV is broken because of duplicated definition of the D$ enabling function.
Mask the one in mach-sunxi to fix the build error when D$ is enabled, and enable the D$ on Lichee Pi Nano.
Ah, very nice. I was always wondering why we would need to disable the data cache, but it wasn't high enough on my list to investigate.
So indeed that both builds and works nicely: md5sum-ing 48MB goes from 21 seconds down to 3 seconds now!
Will merge it as part of the first pull request.
Many thanks! Andre
