Subject: [PATCH v1 1/1] arch: arm: zynqmp: mp.c: tcminit halt both cores in split mode
Date: Thu, 23 Mar 2023 08:25:06 +0000	[thread overview]
Message-ID: <20230323082506.31576-1-neal.frager@amd.com> (raw)

The "zynqmp tcminit split" command should halt both cores and not just RPU1
when configuring the TCM memory for split mode.
