subject:"\[U\-Boot\] u\-boot\-socfpga repository"

Dear Michal,

In message 541334d0.80...@monstr.eu you wrote:

 But creating separate repository for every SoC in u-boot seems to me
 just too much.

We're not talking about one repo for every SoC here.

 Definitely I also really appreciate that Marek volunteers to be responsible
 for socfpga. But that means that guys who are responsible for socfpga failed
 and they are not responding for patches which others are sending to mailing 
 list for review.
 I am not closely following them but did this really happen?

I think the problem is that so far nobody feels responsible for
systematically mainlining the code.  There are some patches here and
there, but usually you cannot build a useful and working U-Boot image
from the existing mainline code.

 If they don't want to maintain their socfpga in mainline and Marek
 wants to do it I will definitely support Marek in this new possition
 to get things done properly but also I just want to make sure that
 this is really happen and isn't it just the part of misunderstanding
 how u-boot community is working.

Probably both.

 Having arm SOC sub maintainers is definitely good concept
 but I am just not sure that creating separate repository fully solve
 this.

You are right - the repository is just one necessary step.
A custodian who knows how the community works and who is willing to
collect patches and synchronize efforts is also needed - this is where
Marek volunteered for now.  If someone from Altera is willing to take
over, such a switch would be trivial to perform. 

Best regards,

Wolfgang Denk

 NO..we'd like to maintain the u-boot-socfpga-next git repo at
 rocketboards.org. Altera(myself, Chin-Liang, and Vince) will actively
 maintain it from now on.

I'm sorry, but that's not the way how the U-Boot community works.

To get patches or new code into U-Boot mainline, these have to be
submitted to the U-Boot mailing list (among other purposes for
archival and that they get stored in the patchwork database).  Then a
peer review takes place, and the responsible custodian finally applies
these patches to the respective custodian repository.  Finally, he
sends a pull request to the next higher custodian - in case of SoCFPGA
that would be Albert as ARM custodian.

There is nothing wrong with you maintaining u-boot-socfpga-next at
rocketboards.org.  It's just that such code does not get into mainline
other than by the procedure described before.  So we need the
custodian repository in any way (unless Albert says he wants to take
stuff directly into the ARM repo - but from the amount of work that is
going on this seems unwise).  Vince may of course volunteer as
custodian for the new u-boot-socfpga repository, but that would be a
community decision, and like everybody else in that role he needs to
earn some reputation first - we haven't seen him at work so far.  In
the meantime, it appears to make sense that Marek fills in the gap.

2014-09-12 Thread David Hawkins


Hi guys,

I'm going to jump in here with an end-user's perspective,
along with an offer of assistance/contribution.

I'm interested in using Altera's SOCs in my designs.
Altera guys - if you look over on the Altera Forum,
you will see that I am very active over there
(basically answering everyone's FPGA questions).

Up until now I have avoided any SoC development kits as
I considered the software support to not have matured
enough. I consider mature code to be code that I can
checkout from mainline, where mainline is U-Boot via the
Denx repos, and Linux via the Kernel repos.

Freescale has done this forever, and I hold their
processors and code in high regard.

Texas Instruments has recently realized that this
is the way to go, and have invested significantly
in this area - as demonstrated by Tom Rini.
TI have dedicated a page to mainlining:

http://www.ti.com/lsds/ti/tools-software/mainlinelinux.page

TI have similarly gained my respect.

The fact that discussion is now occurring for Altera's
SoCs indicates to me that a certain level of maturity has
been reached and that it is now time for me to consider
using these devices.

I'd like to help, and I'm sure Ira Snyder will help too
(most likely more so than me). I would like to obtain
some SoC development kits so as to help with the SoC
experience for end-users.

To aid in this development, I'd like some recommendations
on what hardware to buy. I've included the list below
the body of this email (to save cluttering the flow of
this discussion). Its possible for me to obtain one or more
of these boards.

Which ones are supported in mainline U-Boot and Linux?
What will it take to make it easier for the end-user
like myself?

I would like to be able to buy something like the Critical
Link or Denx modules and simply plug them into my custom
hardware, configure the FPGA fabric with whatever custom
magic I need, have Ira develop a custom drive to that
magic and just have things *WORK*. As an end-user,
I don't want to have to pull a dozen patches off the
mailing list to get a working system.

Altera's success in the SoC market depends on getting
it right with respect to integration with the open-source
community. That integration involves playing by the established
set of rules. Wolfgang and his (creation and) support of U-Boot
is of immeasurable value to the open-source community.

Altera developers, please follow Wolfgang's advice.

   Each module is about $600 at Mouser.

5. Denx MCV board

   These modules look reasonably priced.

The CriticalLink and Denx modules look suitable for my intended

For Linux, we have done a better job than u-boot. You should
be able to have most of what you need from kernel.org for the
Altera Devkits and Terasic SocKit board. The most important
piece maybe the FPGA manager, otherwise the SOCFPGA platform
is just any other A9 board.

The FPGA manager is in-flight:

For U-boot, the upstreaming process has been slow. I admit it, but
it is very high on our to-do list.

Altera developers, please follow Wolfgang's advice.

Wolfgang's advice is valuable and noted. However, it is in Altera's
best interest that we have 1 central gathering point for all our
opensource software support.

I maintain a linux-next git repo at rocketboards for patches that have
been properly reviewed, and acked-by that are destined for kernel.org.
The logic should follow that I(Altera) would do the same for u-boot

 Wolfgang's advice is valuable and noted. However, it is in Altera's
 best interest that we have 1 central gathering point for all our
 opensource software support.

Full agreement here.  But I would like to point out that your point of
view appears to be biased: U-Boot mainline is a community project, and
the community is very much vendor-independent.  So the question we're
trying to solve here is not what is optimal for Altera, but what is
optimal for the community.

As is, current mainline U-Boot is not really working well on most
SoCFPGA systems.  Progress is dissatisfactory slow.  Marek volunteers
to help out now, and you promise to chime in very soon.  I see no
conflict here.  Let us create the u-boot-socfpga repository we need in
any case, and agree with Marek as custodian until Vince has gathered
enough reputation to relieve Marek.  I talked to him - he is not
clinging to that job, he just sees the need to get the current
problems solved now, not in some uncertain future.

Please try to understand that this is totally unrelated to what you do
at u-boot-socfpga-next - it does not influence your work there in
any way.  Ideally, your u-boot-socfpga-next and the mainline
u-boot-socfpga repositories would be just redundant copies.

On the other hand, setting up u-boot-socfpga now allows the community
to make some progress until you (rsp. Vince) start populating
u-boot-socfpga-next and gather experience working with the community.

So it is actually in both the community's and Altera's best interest
to get a mainline u-boot-socfpga set up without further delay.

Best regards,

Wolfgang Denk

Dear Dinh,

 Then I vote for myself as the custodian for u-boot-socfpga. By the way,

May I ask what made you change your mind like that?  First you wrote
that Vince was assigned to to that, and now it's suddenly you?  As far
as I can see, you have not participated in any SoCPGA related code
reviews or discussions in 2014 at all, so what would be the
difference?

 what is the difference between a Maintainer and a custodian? I don't
 understand why if Chin-Liang and myself are listed as Maintainer(s) for
 SOCFPGA, we would have to rely on Marek to pull in our patches for SOCFPGA?

A maintainer is someone who developed some piece of code and feels
responsible for it - who is available as contact person for questions,
or who will be asked to fix any bugs in that code.

A Custodian is one that guards and protects or maintains [1], i. e.
he is responsible for maintaining the design principles of U-Boot and
the code quality even for code he did not work on himself, and for
patches submitted by others.  This is a job that carries a much higher
responsibility than just maintaining your own code.  He will interface
to the actual maintainers of the respective code, negotiatiate
solutions and decide in case of conflicts.

[1] http://www.merriam-webster.com/dictionary/custodian

 Yes, this is the repo will be the one that we will use. I have a couple
 of other things on my plate at the moment and will populate this repo
 shortly.

Thats great, as it means you will not lose any efforts when we start
with u-boot-socfpga now, as you then can start with synchronized
repositories right from the beginning.

Hi all,


Texas Instruments has recently realized that this
is the way to go, and have invested significantly
in this area - as demonstrated by Tom Rini.
TI have dedicated a page to mainlining:

http://www.ti.com/lsds/ti/tools-software/mainlinelinux.page


TI also has a very nice article in Electronic Products
on the benefits of mainlining Linux ...

http://www.electronicproducts.com/Software/Development_Tools_and_Software/The_benefits_of_Mainline_Linux_and_the_mindset_of_upstream_development.aspx

Altera would benefit from a similar philosophy.

Cheers,
Dave
