Subject: [PATCH] ipr: Remove SATA support
Date: Wed, 12 Apr 2023 12:40:15 -0500 [thread overview]
Message-ID: <20230412174015.114764-1-brking@linux.vnet.ibm.com> (raw)
Linux SATA support in ipr has always been limited to SATA DVDs. The last
systems that had the option of including a SATA DVD was Power 8,
which have been withdrawn for sometime now, so this support can
be removed.
