>This command is used to initialize the Flash Image System
(FIS). It should normally only be executed once, when RedBoot
is first installed on the hardware. If the reserved images or
their sizes in the FIS change, due to a different configuration
of RedBoot being used, it may be necessary to issue the command
again though.
