arm: mvebu: DT fixes for 3.8

[Thomas Petazzoni]

Jason, Andrew, Gr?gory,

Here is a set of fixes for the Device Tree data of Armada XP/Armada
370, suitable for inclusion in 3.8.

Thanks!

Thomas

[PATCH 2/4] arm: mvebu: Armada XP MV78230 has two cores, not one

[Thomas Petazzoni]

Contrary to our understanding at the time armada-xp-mv78230.dtsi was
written, the MV78230 variant of the Armada XP SoC has two cores and
not one. This patch updates the .dtsi file to take into account this
reality.

[PATCH 3/4] arm: mvebu: Armada XP MV78230 has only three Ethernet interfaces

[Thomas Petazzoni]

We originally thought that the MV78230 variant of the Armada XP had
four Ethernet interfaces, like the other variants MV78260 and
MV78460. In fact, this is not true, and the MV78230 has only three
Ethernet interfaces.

So, the definitions of the Ethernet interfaces is now done as follows:

 * armada-370-xp.dtsi: definitions of the first two interfaces, that
   are common to Armada 370 and Armada XP

 * armada-xp.dtsi: definition of the third interface, common to all
   Armada XP variants.

 * armada-xp-mv78260.dtsi and armada-xp-mv78460.dtsi: definition of
   the fourth interface.

[PATCH 4/4] arm: mvebu: indentation fixes for Armada 370/XP .dtsi files

[Thomas Petazzoni]

The Armada 370 and Armada XP .dtsi files contained a mix of
space-based and tabulation-based indentation, with not even the same
width. This commit homogenize the indentation by using tabs everywhere
and making the indentation level match the DT information level.

The only non-whitespace change in this patch is the addition of a
semi-colon at the end of the cpus { }; section in
armada-xp-mv78230.dtsi.

Hi Thomas

How many different boards have you tried?

I've not had problems with the board i have. Using the plathome supplied 
kernel, i've rebuilt the kernel, which is a good memory test. Using 
mainline, i've booted a number of times when developing the thermal 
driver and not had problems.

I would hate to disable 2GB of RAM just because your board has a fault.

I've tried only one board, since I have only one.

Indeed. If you report that things work nicely on your board, then let's
discard this fix, and blame a hardware problem.

Thanks!

Hi Thomas

It would be nice to have a sample size bigger than two.

Anybody else have a OpenBlocks AX3-4 and can report if it works or not?

Thomas, could you swap out the RAM module you have for a known good one?
Can you test the RAM module in some other board you know works?

Thanks
     Andrew

At least Gr?gory has one.

Unfortunately, I don't see off-hand which other board I have in which I
could test this RAM module, nor if I have a compatible RAM module to
test things with.

Hi Thomas

White space changes are not fixes, so should not really be submitted
for 3.8-rc. Lets commit these as cleanup in 3.9.

I will however create and submit a patch to add the missing ;

Thanks

Until now I didn't notice any problem on this board with the 3GB enable.

I made more tests since I received this email, I booted (cold and hot boot)
the board dozens of times, and indeed every 5 or 10 reboot the kernel hanged
during boot at line:
"UDP-Lite hash table entries: 512 (order: 2, 16384 bytes)"

After applying your patch, I didn't notice any hang after 20 boots. Do you
have a test pattern which make the kernel to hang each time to be sure that
it is the root of the problem?

I think it hangs at the same place here.

No, I don't have a specific pattern. It just hangs from time to time.
Maybe 1 boot out of 5 or something like that. And it just hangs like it
did for you.

Best regards,

Hi Thomas, Gregory

I've been testing my board some more, using the PlatHome kernel
installed on the device as i received it. I've rebooted the device 20
times and not had a single problem.

I will now swap to a mainline kernel, 3.8-rc2 plus UART patch.

Hi Thomas, Gregory

So, twenty reboots later, no problems at all with 3.8-rc2. Got to
user space every time.

So, what are we doing differently?

BootROM 1.15
Booting from NOR flash
DDR3 Training Sequence - Ver 2.5.DDR3 Training Sequence - Registered DIMM WL -  
BootROM: Image checksum verification PASSED
 ** LOADER **


U-Boot 2009.08 (Jul 27 2012 - 18:23:11)
Plat'Home version: 1.1.1 (Base: Marvell BSP  2.2.3 NQ)

Do you have the same version?

I'm tftpbooting:

setenv bootargs root=/dev/ram console=ttyS0,115200 earlyprintk ; tftpboot 0x80000000 openblocks-dev; bootm

My image contain the kernel and a buildroot rootfs included within the
kernel image and DT is appended. I load it to address 0x80000000,
which puts it at the beginning of CS 3:

DRAM:   3 GB
       CS 0: base 0x00000000 size  1 GB
       CS 2: base 0x40000000 size  1 GB
       CS 3: base 0x80000000 size  1 GB

Thanks

U-Boot 2009.08 (Jul 27 2012 - 18:23:11)

Seems like we do have the same version.

Image is also with an initramfs + appended DTB. My boot command is:

tftp 1000000 192.168.0.14:uImage.armada-xp-openblocks-ax3-4; bootm

So I'm loading to a different address than you.

Hi Thomas

Uboot tells me:

DRAM:   3 GB
       CS 0: base 0x00000000 size  1 GB
       CS 2: base 0x40000000 size  1 GB
       CS 3: base 0x80000000 size  1 GB
       Addresses 14M - 0M are saved for the U-Boot usage.

1000000 would be towards the beginning of this area reserved for uboot.

Could you try moving to somewhere outside of the first 14Mbytes and
see if that helps.

    Thanks
	Andrew

I tried to load the kernel at the same address as you (0x80000000) and
it still hanged after 3 or 4 boots.

Now we have to be sure that we use the same .config and the same compiler.

I'm using mvebu_defconfig and the only option i change is
CONFIG_INITRAMFS_SOURCE to point to my rootfs.cpio.gz file.

But of a long shot. Do you have much broadcast traffic in your
network? I just wonder if u-boot has left the ethernet interface
running, and during boot the hardware received a broadcast packet, DMAs
it into memory corrupting something? My board is on a very quiet
subnet, with virtually no broadcasts.

Indeed, thanks. I'll resubmit an updated patch for 3.9 for some
whitespace changes.

Thomas,

I assume you're running a sed script of some sort.  If so, could you
also hit kirkwood-*.dts*, dove, orion5x?

thx,

Jason.

I am not running a sed script of some sort for now, but I'll come up
with the  kirkwood, dove and orion5x changes as well.

It's not critical, I was only asking in case it was scripted.  There are
a lot more kirkwood dts files than there are armada.  Please don't do
that by hand, that makes my head hurt. ;-)

thx,

Jason.

Jumping back on this old topic of the OpenBlocks AX3 not being stable
with 3 GB of RAM for Gr?gory and me, but being stable for you. Could
you check which revision of the Armada XP you have? Is it A0 or B0?

I.e, check the message:

 SoC:   MV78460 B0

in U-Boot. Gr?gory and I are using OpenBlocks AX3 based on the A0
version of the silicon (so the message I copy/pasted above is *not*
from our OpenBlocks, but a different Armada XP board). However,
PlatHome has been shipping since some time B0 revisions. Maybe it could
explain the difference we're seeing?

Thanks,

Thomas

Hum, ok, so that doesn't explain the problem.

> something?

No, the issue with the window was only that devices can only access the
first 32 bits of the physical address space, so if there is a DRAM CS
configured with a base address higher than 4 GB, then devices shouldn't
configure a window to access this part of the DRAM, because it creates
two overlapping windows (both starting at base 0x0, since in the device
address decoding window registers, the base only has 32 bits, while it
has 35 bits for the SDRAM address decoding registers). And the issue
with window was that the devices were really not working at all. What
we're seeing with the OpenBlocks is some instability: sometimes it
boots, sometimes not.

We're going to discuss this issue further with PlatHome.

Thanks for reporting!

Best regards,

Thomas
