I have an 'older' DreamPlug, that is - effectively - a GuruPlug inside:
# cat /proc/cpuinfo
processor : 0
model name : Feroceon 88FR131 rev 1 (v5l)
BogoMIPS : 1191.11
Features : swp half thumb fastmult edsp
CPU implementer : 0x56
CPU architecture: 5TE
CPU variant : 0x2
CPU part : 0x131
CPU revision : 1
Hardware : Marvell GuruPlug Reference Board
Revision : 0000
Serial : 0000000000000000
UBoot:
Marvell-DreamPlug
SoC: Kirkwood 88F6281_A0
I have managed to get kernels up to 3.11.6 to compile and install OK,
with the 'device tree' option, by selecting 'Marvel GuruPlug reference
board' and 'Marvel GuruPlug reference board (flattened device tree)',
but none of the available options on 3.12-rc seem to work.. I have
tried selecting all the 'Marvell Kirkwood' options, and the 'Marvell
SOC' options, and none of these produces a bootable kernel.
As a test, I temporarily deselected 'Embedded system', and got the
following at boot:
Uncompressing Linux... done, booting the kernel.
Error: unrecognized/unsupported machine ID (r1 = 0x00000a63).
Available machine support:
ID (hex) NAME
00000b44 Marvell OpenRD Ultimate Board
00000939 Marvell OpenRD Client Board
00000915 Marvell OpenRD Base Board
00000691 Marvell RD-88F6192-NAS Development Board
00000692 Marvell RD-88F6281 Reference Board
ffffffff Marvell Kirkwood (Flattened Device Tree)
Please check your kernel config and/or bootloader.
0a63(hex) is 2659(dec), which is, in ~/arch/arm/tools/mach-types:
guruplug MACH_GURUPLUG GURUPLUG 2659
I appreciate that ARM support in 3.12-rc is still a work-in-progress,
but would like to know if this support will be included soon.. I have
- as usual - tried to find some clues online, but haven't found
anything, so far...
Thanks.
Robert Gadsdon.

Robert,

Yes, all Dreamplugs are essentially a Guruplug without the heat problems
:) The big difference is that the Guruplugs have NAND flash and the
Dreamplugs have 2MB NOR flash (for u-boot and environment). DP uses the
micro SD card for rootfs.

Yes, the DT conversion has progressed far enough that we don't need
much, if any, code (board-dreamplug.c) for individual boards. So the
Kconfig options for individual boards have been removed. When you
select "Marvell Kirkwood Flattened Device Tree", it will build a kernel
bootable on any of the kirkwood boards. After the zImage is built, you
need to run 'make dtbs' and it will build all of the available kirkwood
dtb files for you.

Unless you plan on booting this kernel on any of these boards, you can
go ahead and disable building the above legacy board files.

You need to enable CONFIG_ARM_APPENDED_DTB and then append the
appropriate dtb:
$ cp arch/arm/boot/zImage /tmp/
$ cat arch/arm/boot/dts/kirkwood-dreamplug.dtb >>/tmp/zImage
$ mkimage ... -d /tmp/zImage /tmp/uImage
Alternatively, you could upgrade u-boot to mainline which has supported
both the dreamplug and DT booting for a _long_ time now. A lot of folks
are uncomfortable with that, though. Which is why we added
CONFIG_ARM_APPENDED_DTB as a temporary work around.

Yes, that was a bad design decision on the part of Globalscale, nothing
we can do about it. :(

Asking here is the right thing to do. Let us know how the above works
out for you.
hth,

Jason,
Many thanks for the additional info, and suggestions..
I've been running more tests, and still no luck, so far.
For 3.11, I found that selecting the 'Dreamplug' options for Kirkwood
didn't work, and I had to select both 'Marvell GuruPlug Reference Board'
_and_ 'Marvell GuruPlug Reference Board (Flattened Device Tree)', and
then use kirkwood-guruplug-server-plus.dtb:
# cat arch/arm/boot/zImage
arch/arm/boot/dts/kirkwood-guruplug-server-plus.dtb >
arch/arm/boot/zImage_w_dtb
# mkimage -A arm -O linux -T kernel -C none -a 0x8000 -e 0x8000 -n
"linux-dreamplug" -d arch/arm/boot/zImage_w_dtb ../uImage3116

Robert,
Please don't toppost. It makes it very frustrating for others in your
situation trying to solve their problem by reading the archives.

Did you do this? It doesn't sound like you did. Please attach the

Can you cut-n-paste specific results? eg configs, console output, etc?

Your bootloader is, incorrectly, identifying itself as a Guruplug. By
enabling 'Marvell GuruPlug Reference Board', the kernel executes that
legacy board file's machine_init. It most likely isn't using the
appended dtb at all, but we can't say for certain until we see the boot
logs.

Please don't do that. Your board needs kirkwood-dreamplug.dtb,
otherwise it will enumerate a NAND flash that isn't there.
thx,
Jason.

Jason,
Apologies for my ignorant 'top-posting'..
My error in logic was to base my testing on a kernel config which seemed
- to me - to 'work', but was actually _incorrect_, as you pointed out.
I decided to scrub the existing config, and start over, from # make
kirkwood_defconfig, and then select/deselect options for the
DreamPlug. After a bit of trial and error, I now have a working
3.12-rc6 system:
# uname -a
Linux rgdreamplug 3.12.0-rc6 #1 PREEMPT Mon Oct 21 12:54:19 BST 2013
armv5tel armv5tel armv5tel GNU/Linux
Many thanks for your help.
Robert.

whew! I'm glad it was something simple and not a bug in the code.

For future reference, we've been keeping the relevant _defconfig's up
to date so that they build each new version of the kernel, and, if we're
doing our jobs correctly, the resulting kernel should boot without
trouble. If it fails, please let us know.

Anytime.
thx,
Jason.
