[PATCH 0/5] Initial support for Adaptrum Anarion SOC

We've reached the point where we can boot a basic linux system on the
new SOC, and I'm very excited to share the code I've developed in the
process.

This series includes a new driver for the QSPI controller on the chip,
although the flash layout is not specified in the devicetree. The
flash layout is still being worked on, as it depends on finalizing
other components.

The scope of this series is to add enough support to get to a working
system. Keep in mind that the SOC is emulated on an FPGA, and things
are not running too fast. For this reason, as there's yet no way to
get any meaningful speed measurements with the CPU clock at 12 MHz.
Once the silicon arrives, I'll look at the performance aspect and
other aspects that we simply can't support on an FPGA.
