"Lazy loading" defers loading file details until they are
required. This saves mount time, but makes the first look-up
a bit longer.
Lazy loading will only happen if enabled by this option being 'n'
and if the appropriate tags are available, else yaffs2 will
automatically fall back to immediate loading and do the right
thing.
Lazy laoding will be required by checkpointing.
Setting this to 'y' will disable lazy loading.
This defaults Yaffs to using its own ECC calculations on tags instead of
just relying on the MTD.
This behavior can also be overridden with tags_ecc_on and
tags_ecc_off mount options.

If this is set, then block refreshing is disabled.
Block refreshing infrequently refreshes the oldest block in
a yaffs2 file system. This mechanism helps to refresh flash to
mitigate against data loss. This is particularly useful for MLC.
