The Pine H64 board comes with SPI flash soldered on the board, connected to the SPI0 pins (so it can also boot from there). Add the required SPI flash DT node to describe this. Unfortunately the SPI CS0 pin collides with the eMMC CMD pin, so we can't use both eMMC and SPI flash at the same time (the first to claim the pin would win, the other's probe routine would then fail). To avoid losing the more useful eMMC device by chance, mark the SPI device as "disabled" for now. A user or some U-Boot code could fix this up if needed, for instance if no eMMC has been detected (it's socketed).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
