is this right for the 256mb ram?
Im gona go a lil crazy with my ix2-200 today i think and put the uInitrd and uImage on the nand instead of on usb and see how it goes. From what i could tell after seeing a lil more of the boot of mine it keeps saying the uInitrd is full of junk or something. so the uInitrd isnt there to load any of the drivers and such for the device.
and i think by mistake im after deleting the ubuntu vm i was doing the work on DOH!
reg = <0x00000000 0x10000000>

I dont know how or why but for some reason the 3.6 kernel just booted.
There was no output from the serial from the time the uInitrd was loaded then just all of a sudden it was booted.
There was no sata's though so not sure how why or what loaded it. Before this even with my ix2200 selected in the config it didnt work at boot just said board support not available.
Anyone have any idea what the arcNumber for the ix2-200 i saw it before but cant find it again?

Im almost there its booting but I just have 2 majorish problems:
1st: after loading the uImage and uInitrd there is no output from the serial until the system is booted.
2nd: the sata's are not being setup / detected.
Anybody have any idea's?
edit 1:
fixed the serial issue that was just something in the uboot bootargs that i didnt set properly while testing the kernel.
still have the issue with the sata though this is how the serial output is when the kernel gets to the sata part:
edit 2:
Has anyone seen a fix for the sata_mv problem?
i have a working config and dts file but i also need a different entry instead of "iom,ix2-200" as it does not seem to be detecting right just says the support is not there.
But if i just modify the rd88f6281 setup file and use my dts everything works fine except for the sata's.

I just tried the latest kernel source from git as of about 30 minutes ago.
The kernel works by modifying the rd88f6281 config file and creating the dts but then hangs and keeps repeating the following:
Seems like something is broken in either the sata_mv or the ehci controller that stops drives from being loaded or mounted. Anyone run into similar problems? or have any idea's of what i can try next?

How are you getting them to boot?
I have tried multiple time's i think i have a working dts and config but on all kernels i try 3.5, 3.6-rc1 and linux next it seems to hang around the usb and sata_mv initialisation.
Only other thing i need is the proper definition for my device as iom,ix2-200 keep's telling me that there is no support in the kernel.

I think i tried both declareing in uboot and declareing in the dts file and neither worked i still get the same errors as above with the sata_mv and usb like i posted above with the latest git. if the sata's are working for you in git the latest kernel and git then there must just be sumthing up with my dts or board config.

Looks like there was a regression somewhere, I'm seeing the same hang on 3.6-rc1 and the current next cut, the last thing I see is:
Then all is silent. I'm also not seeing my LED turn green, so something is amiss. This was working in 3.5 when I submitted my GFN patch set for inclusion in 3.6. I'm going to take it up with the arm kernel list to see if I can get some pointers on how to proceed.

Has anyone been able to reproduce my findings, where setting nr_ports = <1> allows booting? My GFN is currently working, but with just one port.
And as I mentioned before, the DTS file shows the correct 256 MB of RAM, but the kernel when booting only shows 128 MB. Something else is wrong here.

No, I have two Marvell Kirkwood devices. A GoFlexNet, with 128 MB RAM and now only one working SATA port on 3.6.0-rc1, with nr_ports = <1>. I also have an Iomega iConnect with 256 MB RAM, and only 128 MB accessible with 3.6.0-rc1. I used the appropriate DTB file for each, of course.
Buttzy,
What does your kernel boot log show for RAM on your ix2-200?

Here is my .config file for both:
Kernel config
And kernel log from the GFN:
GFN kernel log
I'll get the kernel log from the iConnect later if you want, but in any case it shows "Memory: 128MB = 128MB total"

Ok, I forgot to set CONFIG_SERIAL_OF_PLATFORM=y on my 3.6-rc1 test kernel. That with SATA set to 1 port has me booting into 3.6-rc1 cleanly. I'm going to retest with SATA set to two ports next.
Edit: 2 ports, same hang I've been chasing...

Cool.
I dont know whats goiing on with mine today now when i build it's telling me there's no support in the darn kernel for my device.
edit:
got that fixed think the dtb was appending properly. I cant seem to get the bootargs right in the dtb file but if i use the ones from the bootloader it boots to the sata_mv problem.
edit 2:
i just tried the nr_ports = <1> and my ix2-200 boots perfectly with it but set it back to 2 and it hangs so it's affecting all kirkwood's it would seem.
Seems like haveing bootargs set in uboot does interfere with the kernel booting i needed to enable

So I think my iConnect RAM problem is caused by U-boot not setting up the registers correctly. I tried to modify them in U-boot but it didn't work, so I need to JTAG now. Anyway when I get that figured out I think it will be ok.
Now that just leaves the sata_mv problem on my GFN, it's something pretty simple I'm guessing.
