Basic U-Boot support is now present for V3s.
Some memory addresses are changed specially for V3s, as the original address map cannot fit into a so small DRAM.
As the DRAM controller code needs a big refactor, the SPL support is disabled in this version.

Do you need that? CONFIG_VIDEO is disabled, so there's no need to reserve space for a framebuffer.
I have task to implement VIDEO support. (V3s come with some LCD support)

Do you even support DFU?
Also in task.
