Kirkwood NSA 310 does not boot with 3.8.3

Kirkwood NSA 310 does not boot with 3.8.3

[Lukas Zapletal]

Hello all,

I have noticed that in the latest stable (3.8) kernels, support for NSA 310 
(Marwell based NAS) has been added.

I tried to boot a kernel with Marwell DT and NSA310 enabled and it can't boot up 
with strange error:

Please check your kernel config and/or bootloader.

Particularly, I dont understand the ID code - it really does not look right. 
This is vanilla 3.8.3. Is there an ARM-dedicated git branch I should rather use 
for early support for NSA310?

Here is my full kernel config:

I hope this is the right mailing list to ask, I apologize otherwise.

Your bootloader doesn't support devicetree.

You'll need to enable ARM_APPENDED_DTB, concatenate your dtb onto your
zImage, then run mkimage on the result to get the uImage.

thx,

Jason.

Jason, thanks for help. It worked great, just for completenes for googlers:

# grep "ARM_APPENDED_DTB|NSA" .config
CONFIG_ARM_APPENDED_DTB=y
CONFIG_MACH_NSA310_DT=y

# make zImage

# make dtbs

# cat arch/arm/boot/zImage arch/arm/boot/dts/kirkwood-nsa310.dtb > /tmp/X
# mv /tmp/X arch/arm/boot/zImage

# make uImage

...
Image Type:   ARM Linux Kernel Image (uncompressed)
Data Size:    3684110 Bytes = 3597.76 kB = 3.51 MB
Load Address: 00008000
Entry Point:  00008000
Image arch/arm/boot/uImage is ready

# cp arch/arm/boot/uImage /boot/uImage-nsa310

UBOOT# ide reset; ext2load ide 0:1 0x800000 /uImage-nsa310; bootm 0x800000

Compared to my patched NSA310 3.6 kernel I don't see console anymore, I guess is 
is just an config option I miss. And LEDs are not working yet.

Thank you

Be careful using this in the future when we go multiplatform, it's not
supported (which Load Address and Entry Point?).  You'll need to use the
mkimage command by hand then.

thx,

Jason.
