* 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, a matching sys'n'_fail flag
* is set in uboot env & a restart performed in the hope that the
* alternate kernel is okay.
* if neither kernel checksums ok and both are marked failed, system 2
* is booted anyway.
*
* Note uboot's tftp flash install writes the transferred
* image to both kernel partitions.
