[DO NOT MERGE v6 00/37] Device Tree support for SH7751 based board

[Yoshinori Sato]

This is an updated version of something I wrote about 7 years ago.
Minimum support for R2D-plus and LANDISK.
I think R2D-1 will work if you add AX88796 to dts.
And board-specific functions and SCI's SPI functions are not supported.

You can get it working with qemu found here.
