a4b86b292a boot: kobs-ng: update kobs-ng for newer kernels
This allows kobs-ng to flash the SPL successfully on the 4.4 kernel used by
the Gateworks IMX boards supporting NAND. The previous version of kobs-ng
worked with the 3.14 kernel but will brick a board making its SPL unbootable
for the 4.4 kernel.

See http://trac.gateworks.com/wiki/ventana/bootloader#nandspl for instructions
on updating the SPL from Linux.

350dd0f9ac kobs-ng: Add support for overriding size
By default kobs-ng will use the size of /dev/mtd0 for the IMX bootstreams.
This patch allows overriding that size in order to reserve space at the end
of the mtd partition for u-boot.img in the case of using an SPL bootloader.

For example, to flash an SPL bootloader that loads u-boot.img from 0xe0000
(14MB) offset in a 16MB /dev/mtd0:

  kobs-ng init -v -x --search_exponent=1 --chip_0_size=0xe00000 SPL
  nandwrite --start=0xe00000 --pad /dev/mtd0 u-boot.img
