Author: mhorne Date: Fri Sep 18 14:40:13 2020 New Revision: 365884 URL: https://svnweb.freebsd.org/changeset/base/365884 Log: arm64: generate ISO release images Some IPMI implementations on arm64 are reportedly unable to load our memstick installer images, but support the older ISO format. Start generating these for arm64. Unlike installer ISOs for other platforms, these images are UEFI-only.
