Thanks for your patch!

Minor nit below.
Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be>

BTW, there are a few more suspicious/incorrect uses of unsigned long:
  - incorrect debug prints on arm64,
  - more unsigned long register values,
  - phys_addr_t
Care to fix these as well?

Thanks!

Doesn't unsigned int make more sense for reg?

Likewise.
