Subject: firmware: add microcode package for Intel
X-Git-Tag: v18.06.0-rc1~1048
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=01020bc74d91a9e02adb6c0cc7bf71d7c446b60f;p=openwrt%2Fstaging%2Fpepe2k.git

firmware: add microcode package for Intel

Compiling the Intel microcode package results in a
microcode.bin and a microcode-64.bin. As we can
decide based on the subtarget which should be used,
we'll only split the required .bin file with
iucode-tool.

x64 will get the intel-microcode-64.bin
All other variants will get intel-microcode.bin

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