[RFC PATCH 0/2] sh: Add Casio fx-9750GIII board support

[Artem Novak]

Add initial board support for the Casio fx-9750GIII graphing calculator,
based on the Renesas SH7305 (SH4A) processor.

The series introduces the board Device Tree 
and minimal SuperH machine registration.

The Casio board Device Tree binding
has been submitted separately.

This RFC depends on SH7305 CPU and SoC support,
which is not yet available upstream.

The board Device Tree passes dtbs_check, and the machine vector compiles using
Casio GCC 14.3.0. The two patches also apply cleanly to Linux v7.3-rc2.
Hardware boot testing with an unmodified upstream kernel has not yet been
accomplished.

I need comments, they are obviously welcome.
