Kernel restoration

To enable kernel restoration, use the -I option to the startup in the buildfile:

startup-boardname -I flag

where flag is 0 to disable checksum verification, or 1 to enable it.

For debugging output, specify at least two levels of debugging via the -v option:

startup-boardname -I flag -vv

If checksum verification is enabled and fails, the entire image is reloaded.

Note: Even if the IFS checksum verification is disabled, a checksum is still performed on the IFS Restoration internal data structure (approximately 32 bytes) to ensure at least some data integrity.
