    Device tree changes to boot FreeBSD on FVPs · 8d2c4977
    Achin Gupta authored
    
    FreeBSD does not understand #interrupt-map in a device tree. This prevents the
    GIC from being set up correctly. This patch removes the #interrupt-map in the
    device trees for the Base and Foundation FVPs. This enables correct boot of
    FreeBSD on these platforms.
    
    These changes have been tested with FreeBSD and an Ubuntu cloud image
    (ubuntu-16.04-server-cloudimg-arm64-uefi1.img) to ensure compatibility with
    Linux.
