Cover letter [DO NOT MERGE v8 00/36] Device Tree support for SH7751 based board
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.
