This series adds support for Sparse images to the fastboot code.
Sparse images are necessary to flash images that do not fit into memory.
This requires more changes than I'd like to have, but unfortunately
we have to change the ubiformat code to flash parts of images instead
of only whole images. This change also makes the newly introduced
'u' flag (u for UBI) in the partition description for fastboot necessary.
Anyway, in the end it works as expected and memory size is no longer
a limit for fastboot.
