arm/km: add boardid and hwkey to kernel command line
We need in some cases a possibility for the kernel to distinguish on which board he is running. On powerpc we did this with different dts files. On arm currently we can't do this, so add boardid and hwkey to the kernel command line and use it later on in the kernel code. Signed-off-by: Holger Brunck <holger.brunck@keymile.com>
