[OpenWrt-Devel] [PATCH 0/5] x86: add support for microcode update

[Zoltan HERPAI]

Hi,

This series will add support for microcode update on x86 targets,
in light of the recent security issues.

While other distributions use an early initramfs approach to update 
the microcode as early as possible, in OpenWrt the earliest place
where we can do this is preinit.

The Intel microcode package is using the source package by Debian,
the AMD microcode package is downloaded from the linux-firmware 
git repository.

This was tested on various Intel-based desktops with ancient BIOSes.

Once the series is merged into trunk, this could/should be backported
into 17.01 and 15.05 without too much hassle.

Thanks,
Zoltan H
