From c89cef3a2cdfb355258890db8cfd2175add5bbee Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 19 Feb 2021 14:45:42 +0000 Subject: hw/arm/armsse.c: Use correct SYS_CONFIG0 register value for SSE-300 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In the SSE-300, the format of the SYS_CONFIG0 register has changed again; pass through the correct value to the SYSINFO register block device. We drop the old SysConfigFormat enum, which was implemented in the hope that different flavours of SSE would share the same format; since they all seem to be different and we now have an sse_version enum to key off, just use that.
