		 * uboot expects to find kernels at 0x140000 & 0x2140000,
		 * referred to as Uimage & Uimage1 in factory FW, respectively.
		 * U-boot variable 'bootImage' controls which is booted;
		 * 0 for the first, 1 for the 2nd.
		 * There's a 3rd partition, Uimage2 (0x4140000), which
		 * I expected to be a recovery image, but is actually blank.
		 *
		 * A kernel is considered suitable for handing control over
		 * if its linux magic number exists & uImage CRC are correct.
		 * If either of those conditions fail, 'bootImage' value
		 * is toggled in uboot env & a restart performed in the hope that the
		 * alternate kernel is okay.
		 *
		 * Note uboot's tftp flash install writes the transferred
		 * image to the active kernel partition.
