[new driver] dev/hpt37xx: Add Highpoint driver for 3740A/840A cards

[jpaetzel]

Summary

Add the hpt37xx driver to the tree.

This driver was written by Highpoint and supports the
3740A 12Gbps SAS RAID controller as well as the 3840A
NVMe RAID controller.

Test Plan

Ideally someone with the hardware would give this a try.

wrt amd64-elf.hpt37xx_lib.o.uu, I'd like us to stop uuencoding objects, they can just be committed directly.

We have a number of binary files in the tree already, some representative examples:

stand/efi/boot1/fat-amd64.tmpl.xz
contrib/unbound/contrib/unbound_cacti.tar.gz
contrib/binutils/ld/emultempl/spu_ovl.o
tests/sys/cddl/zfs/tests/cli_root/zpool_import/blockfiles/unclean_export.dat.bz2

It appears this is not connected in sys/modules?

sys/modules/hpt37xx/Makefile

8–13

why is this needed? Nobody else needs this, as far as I know...

[bcr]

OK from manpages.

Have a HighPoint 2840a that uses that uses this driver. How could I test this out?

I could do a build that has the driver and put it on freefall so you could grab it and test it. Do you have amd64 hardware I assume?

I contacted HighPoint and they are going to do a driver for me to install. Think that will be the route I will go for now.

IMO uuencoding objects is an artifact of when we had a less capable VCS; we have binary files in the tree already and so it should be fine to skip the uuencode.
