https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=216831 Bug ID: 216831 Summary: [PATCH] sys/mips/cavium/octeon_machdep.c: add cavium octeon 'bootoctlinux' boot argument support Product: Base System Version: 11.0-STABLE Hardware: mips OS: Any Status: New Keywords: patch Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: northwoodlogic.free@gmail.com Keywords: patch Created attachment 179652 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=179652&action=edit cavium octeon 'bootoctlinux' argument support patch This patch adds support to set a few bootflags and kernel environment variables from the cavium 'bootoctlinux' uboot loader. With this patch I can do many of the loader things like booting to single user mode and setting an alternate root device. It's not 100% compatible with all loader features because many of them don't make sense on this platform. This was developed and tested on an EdgeRouter Lite v3. For reference, here is the u-boot version I have: U-Boot 1.1.1 (UBNT Build ID: 4670715-gbd7e2d7) (Build time: May 27 2014 - 11:16:22) BIST check passed.
