The Octeon version of U-Boot is based off an older versin of U-Boot

with a lot of features backported. For example, I have backported NVME
support
as well as the latest filesystem code. Since there have been significant
changes to U-Boot (i.e. 64-bit support) that were missing at the time it
would
be a massive undertaking to support the current U-Boot with Octeon or to
push
the Octeon support upstream. While in general the changes to the core
U-Boot
were fairly minimal for Octeon, there were significant changes to board.c.
Hopefully we can get OcteonTX pushed upstream, however, since we are
tracking
the current U-Boot releases. I'm not sure how to go about doing this,
since I
would basically need a branch that I can maintain.
What help exactly do you need here? We already do see partners shipping with
random downstream versions of U-Boot on Octeon TX and every time I see them
missing out on amazing efi_loader fixes, a tiny fraction of my heart dies
:).
So I would really like to see Octeon TX support simply developed fully
upstream. That way your partners (and again their downstreams) can base on
upstream U-Boot versions and are not tied to particular older versions that
may be lacking features or bug fixes.
I maintain U-Boot for Octeon TX platforms at Cavium, which is based on
v2018.01 currently
and also tracking future releases.
efi loader support could be added but lacks customer use case as of now.
Just because the message didn't get to you doesn't mean no customer has
a use case for it :). In a lot of cases people do a list of options
first and then evaluate.
SLES for example will require either SBBR or EBBR compliance for target
platforms. Fair enough, we're a partner and not a customer. Given the
stressed notion security (and that means updates and timely fixes for
known vulnerabilities) is getting across the whole market thanks to
Spectre, I'm fairly confident you'll see more requests coming in sooner
rather than later. We already see heavily increased interest on SLES in
industrial embedded today.
Upstream effort, atleast, for OcteonTX may kick off soon.
That's great to hear! I'll be happy to help out in whatever way I can
(and time permits).
Alex
