  We don't use external toolchains for the defconfigs, unless the internal
one doesn't work for some reason (e.g. microblaze).

  This file should be created in the same patch, otherwise this defconfig
isn't working.

  Also, is it really necessary to have a custom busybox config?

  We don't select any packages in a defconfig, unless they're required
for booting correctly.  We certainly don't want to build Qt!

  These packages don't exist yet; the patches adding them should come
before this patch.

  Note that for these, it could be relevant to include them in the
defconfig - they're not strictly required for booting, but I guess
you want them in practice.

  This patch is more than a month old - how come it's not yet accepted
upstream?

> +BR2_LINUX_KERNEL_USE_CUSTOM_CONFIG=y

  Any reason why the u8500_defconfig isn't appropriate?

> +BR2_LINUX_KERNEL_INSTALL_TARGET=y

  Why?

Until now the ubuntu images available on the igloo community website were
built from the linaro toolchain that's why i used the external linaro toolchain.
I will change the config for the buildroot one.

I need to enable the mdev loading firmware support.
I will change the snowball defconfig file in order to use mdev.

I thought it could be interesting for the end user to have QT built-in in the default rootfs.
I will remove QT from the snowball config file.

I don't know exactly what is the status of the snowball support in the mainline kernel.
As i prefer to use the latest stable release available from igloo, i need to add this patch.

You are right i can use the default defconfig.
I had modified the config file for QT (input devices enabled) but anyway the one attached in the patch serie
didn't match my test config.

  Yes, if you select BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_MDEV then mdev
will automatically be selected in busybox.

  Yes, that was actually obvious, I was stupid to ask it.
