[PATCH 18/44] hw/misc/iotkit-sysctl: Implement SSE-200 and SSE-300 PID r


From: Peter Maydell
Subject: [PATCH 18/44] hw/misc/iotkit-sysctl: Implement SSE-200 and SSE-300 PID register values
Date: Fri, 19 Feb 2021 14:45:51 +0000

The SSE-200 and SSE-300 have different PID register values from the
IoTKit for the sysctl register block.  We incorrectly implemented the
SSE-200 with the same PID values as IoTKit.  Fix the SSE-200 bug and
report these register values for SSE-300.
