There is a mirror of ram located at 0x4000000 which is un-cached. This is
probably useful for DMA, but I am unsure of how to describe it in this device
tree.

The cache-line size is undocumented. Emphirical tests suggest that it is 32
bytes, but I've used 64-bytes to be on the safe side.

Where possible, I have tried to find compatible drivers based on the layout of
registers. However, I have not tested most of this functionality, and anything
aside from clint0, uarths0, and sysctl should be considered descriptive at best.
I would appreciate if anyone could help identify possibly compatible devices,
especially for the timers, watchdogs, and rtc.

The documentation for pinconf devices indicates that #pinctrl-cells is a
required property, but I am unsure what to put for it. Should that be filled in
by a board-specific device tree?

The sysctl device has multiple different unrelated registers. For the moment, I
have split off sub-devices for each functionality. In addition to clock and
reset control, it also contains DMA handshake registers, and power registers. I
have not described those at the moment, and I would appreciate suggestions on
how to best describe them.

I'm not sure what the value of spi-max-frequency should be for external sd-card
slots. Suggestions are appreciated.
