# ALARM: Kevin Mihelich <kevin@archlinuxarm.org>
#  - Removed Gallium3D drivers/packages for chipsets that don't exist in our ARM devices (intel, VMware svga).
#  - added broadcom and panfrost vulkan packages
#  - enable lto for aarch64
#  ALARM: John Audia <therealgraysky@proton.me>
#  - added freedreno driver, PR#1973 and PR#1996
