Missing amdgpu firmware files

[Seth Forshee]

I've received reports from Ubuntu users about missing amdgpu firmware
files with 4.2 kernels. The driver calls out a number of
radeon/*_sdma1.bin files that are not present in the linux-firmware git
repo. Are these files available anywhere (under a license that allows
redistribution), and will they be pushed up to linux-firmware anytime
soon?

Thanks,
Seth
