Author: cperciva Date: Fri Mar 22 06:21:03 2019 New Revision: 345405 URL: https://svnweb.freebsd.org/changeset/base/345405 Log: Obey SPCR AccessWidth parameter. The "access width" value was hard-coded as 2, indicating 32-bit accesses; instead, use the value specified in the SPCR table. This unbreaks the console on EC2 "A1" family instances.
