[U-Boot-Users] [PATCH 1/1] Add support for the hammerhead (AVR32) board

Could you add a few lines describing the Hammerhead board, perhaps with
a link to your site?

This looks pretty good to me. I have a few comments below, and I've
Cc'ed u-boot-users so that more people can comment on this. Please keep
them in the loop whenever you post a new version of this patch.

If you want, I can apply this to my tree as is, and you can send me
incremental patches fixing up the remaining issues. I'll fold
everything into a single patch before sending it upstream.

Hmm...I'm not crazy about adding another board init hook here. Can you
move this stuff into board_early_init_f()?

No, I suppose it needs to go after cpu_init()...

<looks@the stinking pile of crap called common.h>

<cringes@the number of #ifdefs in most arches' init sequence>

Not a single arch seems to implement all the board-specific initcalls.
Help, please?

In any case, please drop the extra spaces after '(' and before ')'.

Hmm...what's the point here? I don't think there are that many ways to
enable gclk3...?

In fact, I'm sort of thinking it might be better to just open-code this
in the board file. It's only a single line of code...

This gives (25000000 / 1) * 5 = 125 MHz. Please update the comment.

Sure you don't wanna crank it up to 150 MHz, btw? ;-)

It turns out that you can use "console=ttyS0 root=mtd1
rootfstype=jffs2". That's shorter and makes it possible to boot a
kernel without Block Device support.

I don't think CFG_MALLOC_END and CFG_MALLOC_START is used anywhere.

Some people think "U-Boot> " looks nicer. Or you can make it something
custom, e.g. "Hammerhead> ". It's up to you, really.

Hmm...this needs to be coordinated with Ben Warren's ethernet init
patches somehow.

If you call it "board_eth_init()" instead, we can simply chop off this
hunk when Ben's patches are in, and it will all Just Work. Hopefully.

You'll find a short desc. of the hammerhead board on top of the

Would be great if you could apply the patch to your tree. Please find
below the incremental patch that should fix all of the remaining issues.

You won't need to touch this file.  Please see how it's done in the 
'next' branch of the net repo on git.denx.de.

...though I'm not sure what the problem with incremental patches is,
assuming someone is willing to merge them before they finally go
upstream. I am willing to do that.

Yeah, but it you don't touch this file, it will only work in your
'next' branch. If you don't rebase your next branch, I can pull it into
my tree and get everything sorted out before the merge window. Hey,
I'll even fix up a few existing boards :-)

The other possibility is to apply the patch with this hunk present and
throw it out before I finally merge it after your changes are in. That
was my initial suggestion.

What do you think?

I personally think they're hard to follow, add unnecessary dependencies 
and pollute the changelog.  But that's just my opinion.

Just another fun aspect of having non-orthogonal branches and patches.  
The best solution would be for Wolfgang to pull my patch into mainline 
(for r1.3.4).  Technically, a few rounds of the submission were posted 
before the merge window closed, so maybe he'll be in a good mood after 
vacation :)  Otherwise, I don't care - your idea works.  You can move a 
few or all of the macb-using boards over and that would be cool.

I was thinking of creating some kind of "staging branch" where it could
evolve until some time before the next merge window. Then I'd just do a
"git rebase -i master" and suck it into my main branch as a single
commit, so the changelog should end up nice and tidy. Sort of like how
-mm works, except using git instead of quilt.

Not sure if it's a good idea or not...I still feel my workflow isn't
fully optimized ;-)

The alternative is doing a few more full respins on the mailing lists.
I personally think full patches get tiresome to review on the third
respin or so...so I kinda prefer incremental patches once things are
in reasonably good shape.

I think I'll create a "hammerhead" branch and pull your "next" branch
into it. It will be kind of volatile anyway since I intend to rebase it
at least once before doing the final merge, so if it doesn't work out,
I can always drop your tree.

That said, your patch paves the way for a lot of nice cleanups in
net/eth.c, so IMO it would be a pity to have to wait another release
cycle before starting that work. In other words, feel free to add a
huge Acked-by from me and push it for 1.3.4 :-)

As for the other macb-using boards...maybe it would be easier to take
that through your tree? Heh, non-orthogonal patches again...

I was just going to rebase and fold the hammerhead patch to prepare it
for the next merge window when I noticed that MAINTAINERS isn't updated.

Can you send me a patch adding yourself to MAINTAINERS, assuming you're
the one that will be maintaining this board?

Hi & welcome back from holiday :)

According to your request...

Thanks :)

> According to your request...

This was rather more than I asked for, and it didn't apply to the
hammerhead branch I already had.

After resolving the conflicts, I ended up with just a change to
MAINTAINERS, so I've committed only that part. The rest is already
there (except the net/eth.c stuff which shouldn't be necessary anymore
after Ben's patch hit mainline)

Could you have a look at the result at

	git://git.denx.de/u-boot-avr32.git hammerhead

If it looks ok to you (and still works), I'll fold it all into a single
patch tomorrow. The commit messages are somewhat bogus...I'll fix it up
at the same time.

[U-Boot-Users] [patch 1/1] Set GD_FLG_RELOC for boards skipping relocation to RAM

[Fundu]

when would you not want to relocate ? 

my understanding was when the bootldr come up it first runs the monitor and then relocates to ram and shoots off from there. right ? 

any clarification would be appreciated. TIA !

Hi,
On some platforms U-Boot is loaded from flash to RAM memory by a ROM bootloader.

Currently I even cannot compile it, due to some not only to our board 
related errors. I'll check them and give you feedback asap or not 
later than tomorrow.

Done. I've also applied a couple of other fixes due to recent API
changes, so it should at least build now.

Ah great!

Are those already committed to your hammerhead branch? Right now I 
couldn't pull anything new. 

Maybe you can check those in so that I can pull and test the u-boot.

    hammerhead: Define CONFIG_ATMEL_MCI
    
    Since the MMC driver was moved into drivers/mmc, you now need to define
    CONFIG_ATMEL_MCI in addition to CONFIG_MMC to include it.

[U-Boot-Users] [PATCH 1/1] Add support for the hammerhead (AVR32) board

[Julien May]

I am currently having problems in initializing the eth.

in net/eth.c the following is defined

static int __def_eth_init(bd_t *bis)
{
	return -1;
}
int cpu_eth_init(bd_t *bis) __attribute((weak, alias("__def_eth_init")));
int board_eth_init(bd_t *bis) __attribute((weak, alias("__def_eth_init")));

this is not calling my implementation of board_eth_init.
I see and like the idea behind this but do not understand why my 
implementation is not getting called...

btw. I did update the implementation function header from void to int.

Hmm, that's probably the "weak functions cannot be overriden by
functions defined in their own file" crap that was discussed earlier.
Can you try moving board_eth_init() into hammerhead.c?

Which reminds me...Ben posted a patch which did that for all the
existing avr32 boards. I should probably apply it.

> btw. I did update the implementation function header from void to int. 

Yeah, that's probably a good idea too :-)

Did so and it works now. I could make for this an incremental patch and 
send this to you.

Otherwise I wait until you applied bens patch and test again hammerheads 
functionality in u-boot.

That would be great.

I've applied it, but it doesn't affect hammerhead. It just does the
same change you just did to a few other boards.

Please find below the incrementel patch. This patch just fixes the eth 
stuff of our board. As hopefully understood right the patch from ben 
sould fix the rest.

Yeah, that should do it, thanks. I think it's time to create a "next"

Could someone explain me what this message has relation with AVR32?
This is 100% microblaze relate problems.
Please change subject and cc to me if you have any problem with latest U-BOOT
