Comment 2 for bug 1701137

This is really more of a feature request than a bug report, but I couldn't find a better place or tag to file this. So my apologies if this isn't the right way of requesting this.

For a way to reproduce this: Without ARCH_SUNXI a kernel does not contain the pinctrl and clock drivers crucial for any kind of I/O. The only thing that should work is "earlycon=uart,mmio32,0x1c28000".
Enabling ARCH_SUNXI should make the proper UART driver work, so "console=ttyS0,115200" would give any output. Enabling the other symbols mentioned above allow mass storage via uSD card and USB.
