Author: markj (src committer) Date: Tue Aug 28 21:51:59 2018 New Revision: 478330 URL: https://svnweb.freebsd.org/changeset/ports/478330 Log: sysutils/devcpu-data: Provide a file for loading Intel updates at boot Extend the port so that users may easily apply microcode updates using the method implemented in src r337715. For now, this just consists of providing all Intel microcode update files concatenated together as a single blob in /boot/firmware.
