Hi,

I have zero knowledge about Allwinner D1, however your console log is
really short, almost no devices here. As it is not possible to mount
root this way (no device where any file system could reside on), it
is possible to use memory filesystem (mfs) embedded in kernel for small
root.

Also, at 'mountroot>' prompt, try pressing '?' to get valid disk boot
devices list, probably it is empty because lack of devices. Using mfs
allows boot to multiuser with some minimal filesystem, which is
important milestone when working on support for new system, in my eyes.

Milan
