Subject: firmware: add microcode package for AMD
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8fb34763453d305365947bfca9766bf8a7150d2c;p=openwrt%2Fstaging%2Flinusw.git

firmware: add microcode package for AMD

Use the Debian repository for sourcing the ucode files.

Current (20171205) includes support for fam17h CPUs already.

The microcodes will be updated from preinit via a common
script - that's the earliest place where we can do it.
