Hi, there
I'm planning to port linux on a SH7727 based board,
but I couldn't find CPU_SUBTYPE_SH7727 from arch/sh/Kconfig.
Is SH7727 supported?
Regards,
Jeongdo Son

SH7727 is an ancient SH3-DSP. You can poke around arch/sh/Kconfig for
subtypes that select CPU_SH3 && CPU_HAS_DSP to find a starting point.
Presently this includes SH7710/SH7712/SH7720/SH7721. Adding SH7727 should
be trivial, just follow the existing conventions for those parts. A lot
of the old SH3/SH3-DSP variants are also completely compatible with each
other (pin and otherwise), so you may always want to make sure that it's
not already supported under a different subtype qualifier.

Hi, Paul
Thanks for your comment.
Yeah, adding SH7727 seems to be not so difficult.
Now I think I can move on to the next step.
Best regards,
Jeongdo Son
