Hi:
I would like to add some info for Edgerouter 6
(and presumably ER4, and maybe also ER12?) to install64.octeon.
The document is great but it won't get a new user booting on the new
4-core machines with MMC drives.
I tried to make it as brief as possible while pointing the user in the right
direction, so for example it mentions that you're going to need to drop
bsd.mp into the msdos kernel loader partition but doesn't explain how
to do that. Seemed to be the right level of detail for this document.
Here is a diff with my additions. Diff is from
/OpenBSD/6.4/INSTALL.octeon.
