Subject: gemini: Break out USB to packages
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=10ec966f7ba7471a8af437c317cdcc5ef8865e8d;p=openwrt%2Fstaging%2Fluka.git

gemini: Break out USB to packages

This creates a new kernel package for the fotg210 host
controller and uses that with the gemini to shrink the
kernel. The SQ201 needs the USB2 PCI package as well.

The build system required me to make kernel_oldconfig
beofore it would build without errors so some minor
unrelated Kconfig entries are changed.
