Subject: [U-Boot] ARM: flush_dcache_all for PSCI
Date: Mon, 10 Nov 2014 13:57:51 +0100	[thread overview]
Message-ID: <5460B64F.2040306@siemens.com> (raw)

Hi all,

I'm trying to get Marc's CPU hotplug-anabling patch [1] for sunxi
working on a B-Pi. After the first discussion it became clear that we
need something like flush_dcache_all in the PSCI monitor (I don't think
we need an icache flush, do we?). Does anyone have a clever suggestion
how to reuse the existing code for that? Or do we really need to
re-implement everything, in the worst case in assembly?

Thanks!
Jan
