Subject: [PATCH v3 14/27] powerpc/powernv/pmem: Add support for Admin commands
Date: Fri, 21 Feb 2020 14:27:07 +1100 [thread overview]
Message-ID: <20200221032720.33893-15-alastair@au1.ibm.com> (raw)
In-Reply-To: <20200221032720.33893-1-alastair@au1.ibm.com>
From: Alastair D'Silva <alastair@d-silva.org>
This patch requests the metadata required to issue admin commands, as well
as some helper functions to construct and check the completion of the
commands.
