Google HowYaffsWorks

The same code actually handles both with a few extra checks for YAFFS2 mode.

YAFFS1 uses deletion markers which means that any block can be
collected at any time.

YAFFS2 does not have deletion markers which means we have to be
careful with blocks we collect. This constrains the block selection a
bit.
