Hi,

I apologise for the na?ve nature of this question,
but I do not seem to be able to make any progress of my own accord.

I would like to boot the mainline kernel - ideally v3.10 and v3.11-rcX -
on snowball. The reason being to verify CPU hotplug which
seems to be broken on shmobile, though that is tangential to this post.

My procedure, which does not work, is as follows.
I have tried a number of different versions all with roughly
the same result.

1. Build kernel
# git checkout v3.10.2 # I have tried several over versions too.
# make u8500_defconfig
Edit .config to enable CONFIG_ARM_APPENDED_DTB
# LOADADDR=0x100000 make uImage dtbs

2. Append dtb to zImage and recreate uImage
mv arch/arm/boot/zImage arch/arm/boot/zImage.tmp
cat arch/arm/boot/zImage.tmp arch/arm/boot/dts/snowball.dtb
/bin/sh scripts/mkuboot.sh \
	-A arm -O linux -C none  -T kernel \
	-a 0x100000 -e 0x100000 -n 'Linux-3.10.2' \
	-d arch/arm/boot/zImage arch/arm/boot/uImage

3. Boot uImage from u-boot
Snowball $ setenv ethaddr 3e:c4:73:05:d1:a1
Snowball $ bootp;bootm

This is as far as it gets.
