Subject: [PATCH v2] remoteproc: xlnx: allow single core use in split mode
Date: Tue, 10 Jun 2025 12:27:38 -0700 [thread overview]
Message-ID: <20250610192738.3095247-1-tanmay.shah@amd.com> (raw)
It's a valid use case to have only one core enabled in cluster in split
mode. Remove exact core count expecatation from the driver.
Signed-off-by: Tanmay Shah <tanmay.shah@amd.com>

Change in v2:
- limit core_count to max 2
