The Nanopi R2S currently only works with an older U-Boot v2021.10.  This
commit only relocates the CN9130 patches to a sub-directory.

All Infix builds should be signed, but for some test equipment, and
during board bringup, this may be too much of a hassle.

Support for this is based on the upstream Buildroot R2S defconfig and
the myLinux extensions and stripped-down kernel defconfig.  For more

Please note, due to the lack of a VPD on the board, and some very poor
devicetree skills by yours truly, Infix currently refuse to boot on this
board.  An in-devicetree factory-password-hash node has to be added, and
will be done soon.

Loss of BusyBox "show others", uboot-tools, and e2fsprogs, are likely
due to resolved dependencies from other packages.  E.g., Frr requires
bash.

Since the Nanopi R2S does not have a VPD, we use this mechanism to set
the default admin password.  Without one, Infix will refuse to generate
the factory- and failure-config files, and thus refuse to start.

On custom boards in production we have VPD in ONIE format that contains
a per-device unique SHA256 hashed admin user password.
