Restrict cpu_up_send_sgi() function to arm32 code as it's used by arm32
platforms only and unreachable on arm64 (Misra rule 2.1).
Signed-off-by: Grygorii Strashko <grygorii_strashko@xxxxxxxx>
---> Logically cpu_up_send_sgi() should be moved in arm32, but source is
"GPL-2.0-or-later" while possible destination is "GPL-2.0-only", so put it
under ifdef for now.
:(. I don't know if we will ever solve this license mess... Looking at the
list of platform using cpu_up_send_sgi(), all the platforms are 10+ years old
and to be honest except maybe the rcar2 development platforms. I doubt there
are anyone using them.
So I would be tempted to get rid of them and mandate PSCI when booting on Xen.
Bertrand, Michal, Stefano any thoughts?
I am OK with that.
I am OK with that to.
I'd like to clarify if this patch as is will be merged as is?
or expected to be superseded by clean up series?
Meanwhile for this patch:
