Subject: [PATCH 2/8] RISC-V: Don't set cacheinfo.{physical_line_partition,attributes}
Date: Mon, 27 Aug 2018 11:42:37 -0700 [thread overview]
Message-ID: <20180827184243.25344-3-palmer@sifive.com> (raw)
In-Reply-To: <20180827184243.25344-1-palmer@sifive.com>
These are just hard coded in the RISC-V port, which doesn't make any
sense. We should probably be setting these from device tree entries
when they exist, but for now I think it's saner to just leave them all
as their default values.
