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. > 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 Unless you plan on booting this kernel on any of these boards, you can go ahead and disable building the above legacy board files. > ffffffff Marvell Kirkwood (Flattened Device Tree) > Please check your kernel config and/or bootloader. 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. > 0a63(hex) is 2659(dec), which is, in ~/arch/arm/tools/mach-types: > guruplug MACH_GURUPLUG GURUPLUG 2659 Yes, that was a bad design decision on the part of Globalscale, nothing we can do about it. :( > 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'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.

It doesn't sound like you did. Please attach the console boot output. > I've been running more tests, and still no luck, so far.

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. > # cat arch/arm/boot/zImage > arch/arm/boot/dts/kirkwood-guruplug-server-plus.dtb > > arch/arm/boot/zImage_w_dtb Please don't do that. Your board needs kirkwood-dreamplug.dtb, otherwise it will enumerate a NAND flash that isn't there. thx, Jason. ^ permalink raw reply [flat|nested] 6+ messages in thread

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.
