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. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

Add --chip_0_size param to override the size of the mtd partition which is
|
|
required if the SPL does not occupy the entire partition. For Gateworks
|
|
Ventana boards the 'uboot' partition contains both the SPL and uboot.
