Since we do not wish to modify the tiny-image from anything but really tiny, lets use that infrastructure and add the bootstrap package group to create initramfs (not exactly a completely usable system) which can be used for basic board bringup. This generates cpio around 36-40MB which should be usually fine for even smaller systems (Ofcourse, this is much larger than tiny-image which is around 6MB size). The packages are organized per size to allow easier customization if desired. Signed-off-by: Nishanth Menon <nm@ti.com> --- Changes since v1: * review comments incorporated.
