svn commit: r287934 - head/sys/boot/efi/loader

[Warner Losh]

I have both a modules-only kernel (checked in as MINIMAL, but it
needs a little love).

I also have most of the modules loading automatically infrastructure
in place, except for some code to parse data and create devd.conf
scripts on boot. Konstantin asked that I write this before pushing
the bulk of my work in.

There will be a chore to convert all the PCI drivers in the tree to
mark the PNP data (maybe tweaking it a bit), but it’s pure grunt work.
I’ve done all the USB and (less relevantly) PC Card.
