There are more things wrong with the above:
1. It's not multi-platform safe: any ARM kernel with sh73a0 or r8a7740
support will treat all SCIFs and HSCIFs as SCIFA/Bs.
2. It wasn't updated for newer SoCs, e.g.
- r8a73a4 has SCIFA/B, too,
- R-Car Gen2 has all of SCIF, HSCIF, SCIFA, SCIFB, which isn't
supported by the current logic at all.
Looking into it...
