[PATCH 1/2] Moving Marvell Dove platform defaults to ARMv7

[Konstantin Porotchkin]

Hello, Nico,

I believe the past two patches were OK. Are you going to integrate them?

Thank you for your help
Konstantin

BTW, does this mean that all PJ4's are ARMv7 capable now?

If so, can the PJ4 entry in arch/arm/mm/proc-v6.s be removed?

sure, we will prepare a patch that removes the PJ4 from that file and
from arch/arm/boot/compressed/head.S
Haojian, can you please approve?

I'm OK on this change. MMP2 (PJ4 core) is also used as ARMv7 capable.

Thanks

So I did remove those entries.  That also allows for the Dove kernel to 
be compiled using Thumb2 without any additional changes.

Yes, of course.  And it works just fine.
