Add support for USB-A9263 board manufactured by Calao Systems
(http://www.calao-systems.com/).
Code is based on old U-Boot sources (2010.09) released by Calao and
existing AT92SAM9263-EK code.

For the MAC address, I think we should get from environment or other

Should I also update (in separate patch) at91sam9263ek board
(code is the same there, bad side is - I don't have that board to test)?

I don't understand something here:
- this address is hardcoded in AT91bootstrap (as well as image size - 0x31000),
- I can change it, but it will not boot on "stock" board - should we force
people to recompile AT91bootstrap if they want to use new U-Boot?
or
- Should I add low-level initialization to boot U-Boot from Dataflash
without AT91bootstrap (this is a bit more work)?
or
- There is another way I'm not aware of (perhaps relocate U-Boot in RAM)?

Mateusz Kulikowski

Do you have the source code?

Not the preferred way ...

Thats the way I would prefer! We decided for the siemens at91 board
ports I recently posted, see here:
[U-Boot,v1,1/3] at91: add defines for reset type
http://patchwork.ozlabs.org/patch/285365/
[U-Boot,v1,2/3] arm, at91: add Siemens board taurus (based on AT91SAM9G20)
http://patchwork.ozlabs.org/patch/285366/
[U-Boot,v1,3/3] arm, at91: add siemens corvus board
http://patchwork.ozlabs.org/patch/285367/
to start a try using spl instead of at91bootstrap. I hope to get this
ASAP (serial output works :-) running and post a RFC patch. They boot
from NAND but that should be no big problem to add dataflash support ...
> or
> - There is another way I'm not aware of (perhaps relocate U-Boot in RAM)?
You need always some first stage bootloader, currently this is
at91bootstrap, but we should integrate this into U-Boot SPL code ...
U-Boot gets relocated in RAM, but that is later in the boot process...
bye,
Heiko

You can use GPIO API for USB-A9263 in this patch. And send another patch
to fix at91sam9263ek board (I can help test the patch for at91sam9263ek
board).

Yes, that's true. And this is a pain for us :(
Here just a reminder for the text base.

(If you plan to modify the text base, you must ask for that.)
For new version bootstrap, we have change this address to 0x21f00000 for
boards only have 64MiB SDRAM.

I am working for SPL for Atmel EK boards, now focus on sama5d3xek board.
After finished, I will submit then patch and go on working for other board.

We just decided to go this way for the siemens boards too...
(Just started, serial seems to work in spl code)

The crux is that in fact u-boot is relocating u-boot in any case (the
most cases). It will place some stuff at the very top of the RAM (gd_t,
malloc arena, stack, ...) and calculate depending on some runtime values
(reserved ram, display vram, ...) where to place the resulting u-boot
image. The u-boot image will be placed right after the reserved place to
fill up the whole top of your RAM.
Therefore it depends on your compile time and runtime setup if there
will be an overlapping between running u-boot image and resulting place
when doing the relocation. It is likely to collide with the running
u-boot image while relocating if it is placed just 1MiB from top of the RAM.
We decided to change at91bootstrap and u-boot for to have another load
address for some boards in the past cause of real problems there. There
where strange errors like running system but crashing when using a
specific command.
I really recommend to leave a bit more space for u-boot runtime code to
do it's relocation ad therefore use a smaller ram location.
The best would be to get SPL working ASAP to have the setup of load
address in just one piece of code ... A long outstanding wish of mine,
but had no time to implement.
Bo and Heiko, could you both please post some RFC of your code to get
this in line?
Best regards
Andreas Bie?mann

Yep, see this on my recently posted boards too ...

I just started with it, I have only serial running under SPL Code,
need to write a small nand driver ... clean up ... and then I can
post a RFC ... hope to do this soon ...

I would really like to see that removed. The dataflash thing is another
part on my todo list. The common mtd code can handle these devices too
(see for example at91sam9n12ek, at91sam9x5ek, ethernut5 sam5d3xek and
top9000). I did some short testing on that for at91sam9263ek (at home,
never sent to the list) and it worked basically. Will see if I find it
this evening, clean up and post it this evening CET.

A good way to avoid 'unused parameter' warnings is to just leave the

As mentioned in another mail. Just one point more. It is up to you to
set a correct value here. It may be ok for your setup to just leave 1MiB
to top of RAM, but I doubt it really works in any case cause of the
relocation. Please hack the code and print out the '__image_copy_start'
and '__image_copy_end' symbol position before and after relocate_code().
Beware, arm moved to generic relocation, you have to look up
common/board_[fr].c.
Also it may happen that the relocation clobbers some stuff in rel_dyn or
bss sections.
If you can prove it will not collide at that position I'm fine to take
it as is.

Just a pointer ... you could use the CONFIG_CMD_MTDPARTS define. The
same mtdparts provided to the kernel could be used in u-boot -> 'nboot
kernel'. Some newer at91 boards use that, I personally find it quite useful.

Malloc is 152KiB, gd_t is smaller than 1KiB, your u-boot is smaller than
196KiB (as you mention in some comment) ... It may fit into the 1MiB
gap, if there is no other runtime defined parameters changing the
relocation address ...
But this is only true if you do not add more features, for example
ubi(fs) which has some more runtime code and requires more than 512KiB
malloc arena, about 4MiB recommended. Yust my 2?, you should really have
a look for ubi(fs) when using NAND devices ...
Apart from that your patch looks good. Please address my concern about
dataflash driver and Bo's comments and send a v2 for inclusion.
Best regards

Yes I do, it even seems to work properly after recompilation (with baremetal toolchain).
I should be able to do low-level init for this board.
Of course, first - SPL support for AT91 must be ready if I understand correctly (who will do it is different thing).

Mateusz

Like I wrote in other mail, I should be able to do lowlevel init for this board.
Just have to read/learn/play with SPL first (never used it before).
But this part I prefer to do later (somewhere next month).

What kind of Dataflash have you used?
Dataflash on Calao (at45db021b) does not have read-id command.
It also has different command set than more recent version (*021d).
It may be tricky to probe and operate it without modifying SPI drivers.
For now I will move partition code to "main" board file;
If I figure out how to handle that Dataflash - I'll update the code.
Unless I'm missing something?

AFAIK this doesn't go well with C, and will not work on default compile flags set by u-boot.

Thanks for the tip about board_[fr] - I was not aware of it and used old boot mechanism.
I'll update config file to use generic board code.
As for the memory concerns, I did little test:
- enabled debugs in board_[fr].c (they print nicely memory layout),
- Filled u-boot binary with commands/garbage to reach max size supported by AT91bootstrap (200704)
- Flashed, booted the board. Below - log (parts):

I'll do it after I have SPL working - it will not fit now.

It will not be possible to add more features until I get rid of AT91bootstrap.
I prefer to stick to config that may used on "stock" boards (kernel is located on separate partition, so no FS driver is needed)

Add support for USB-A9263 board manufactured by Calao Systems
(http://www.calao-systems.com/).
Code is based on old U-Boot sources (2010.09) released by Calao and
existing AT92SAM9263-EK code.

Sorry, haven't realized that. I have to check which dataflash was
attached to that board.

_plenty_ of space is not true here (in my understanding), but 410 KiB
will be enough ;)

Could you please use the generic GPIO API here? Is it Ok for you to not
mux the pullup for the ready pin?

Here you could really use the gpio_direction_output(). I sent out an RFC
lately to define new GPIO_PIN_Px() macros. As long as that RFC is not
reworked and included I think it is Ok to use the CONFIG_ATMEL_LEGACY
defines.
Please switch to the generic GPIO API for defining GPIO direction and
switching GPIO, even on AT91. On the long run we will remove the
redundant at91_pio API, at least regarding plane GPIO functionality.
Therefore it would be good to use that API now, even if it costs some
function calls currently.

Heiko proposed a solution for unifying macb reset sequence.
@Heiko will you send another patch?

Here we could also use the generic GPIO API. Beside that, did you really
copy the at91sam9263 here? IOW, do you really have a slot for MMC/DF
here and therefore require to switch the clock?

Beside these minor complaints there is nothing to stop inclusion for
2014.01. Please stay tuned and do not send v3 immediately cause of the
ongoing change for GPIO API and consolidation of macb reset.
I think another ping from your side in about two weeks would be Ok, if
you haven't seen changes in the two mentioned points on the list.

I thought I wait for your GPIO update patches, and rebase my patch-
serie for the siemens boards on them ...
Ok, based on the spl patches from bo shen, see
http://lists.denx.de/pipermail/u-boot/2013-November/166272.html
I can sent soon the "phy_reset" patch, if the patch passes a
"MAKEALL" ;-)
bye,
Heiko

I've checked schematics - board has external pull-ups, so I can use generic GPIO.

Do I understand correctly, that for all ports that I use (via generic GPIO) I should create "temporary" defines
(with hardcoded gpio#)?
Perhaps I'm missing something, but I currently see no other way to get GPIO# (It will change once your RFC is included).
Of course CONFIG_ATMEL_LEGACY has to stay, as atmel_nand uses CONFIG_SYS_NAND_*_PIN and is still using old API (I guess this also needs fixing).

+1
I will also switch usb_a9263_macb_hw_init() to generic GPIO (and remove re-enabling of pull-ups as they are dropped by at91_macb_hw_init).

I copied (see at91sam9263ek.c:256).
I've checked board schematics and this pin is floating, so for v3 I'll drop it.

Ping :)
Do I understand correctly, that phy_reset RFC will be soon applied, then I should post v3?
Or should I wait for your GPIO RFC?
In the meantime I will start playing with SPL, as u-boot image grows slowly and soon I'll be forced to cut another features just to keep it small enough.

Mateusz

please use the freshly defined GPIO_PIN_Px() macros from [1].

The series includes change for atmel_nand [2], therefore you can remove
that switch.

From: Mateusz Kulikowski @ 2013-12-02 22:30 UTC (permalink / raw)
To: u-boot
Add support for USB-A9263 board manufactured by Calao Systems
(http://www.calao-systems.com/).
Code is based on old U-Boot sources (2010.09) released by Calao.
Signed-off-by: Mateusz Kulikowski <mateusz.kulikowski@gmail.com>

Changes for v3
- Updated Makefile to a new build system
- Use generic GPIO for NAND and MAC (requires new GPIO patches)
- Use common at91 phy reset
- Dropped spi0 clock setup (pin is unused)
- Fixed PHY address as 0x0001 and dropped PHY autodetect
(no need for autodetect - PHY address is bootstrapped to 1)
