[Yaffs] [Yaffs-archive] YAFFS checkins

[Charles Manning]

Hi Yaffsers

I have just checked in some changes.

yaffs_guts.c:

The recent haggle over reading back a spare area before deletion in 
yaffs_DeleteChunk() has been resolved by making this an optional compile 
based on whether MTD verification is enabled. YAFFS does not need mtd 
verification since it supplies its own. By preference, YAFFS uses mtd 
CONFIG_MTD_NAND_VERIFYT_WRITE enabled.

An extra check has been added to ensure that the block size is large enough 
for soft deletion to work. Currently this would become an issue around 2GB 
which is pretty big!

Documentation/yaffs2.html:
A few typos etc.
Added a description of the resize tracking algorithm.
