Hi Andreas,
We have been shipping 2011.03 for some time and internally are planning
to use 2012.07 when it is released since we are tracking the top of
trunk. We have made a lot of improvements since then and added a lot of
new capabilities.

Hi ,
I have basic knowledge of porting u-boot to a new board. But now i have got
a task to port u-boot on cavium mips based board. As i know that mips
architecture is already supported, but will it support all cavium octeon
mips variants?
I guess no. I had to work with some non mainlined version of u-boot
provided by cavium a year ago (or something around that). At that time
we got a
---8<---
abiessmann@azuregos % git grep U_BOOT_VERSION include/version.h
include/version.h:#define U_BOOT_VERSION "U-Boot 1.1.1"
--->8---
:(
AFAIR there was a lot of basic stuff missing in mainline U-Boot to get
Cavium mips64 running at that time so I didn't start to port these
proprietary changes (well it would not have been accepted the way it was
written down; beside that cavium forced us to sign a NDA for that piece
of GPL code).
I have not followed their open source efforts since then, but I saw a
lot of work on the linux-mips list by David Daney and I think Aaron
Williams is working for Cavium too and is on this list. Maybe one of
them can comment?
Please put some light on this. I would be glad if you guys,
give my some idea to where to start with or suggest some documents which
will help me understand and port on a new architecture
You should not hesitate to contact their support and ask for proper
mainline support of u-boot ;)
Enough Cavium bashing.
Regarding your question for documents, I'm sorry I can not help you
here. I recommend start working with some mainlined device which is
comparable, get firm with the architecture, try to find commonalities,
get the new cpu in u-boot step by step.
Best regards
Andreas Bießmann
