* 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.
