[U-Boot-Users] JFFS2 speed enhancement patch

Hi,

for the sake of speed I repaired the header CRC calculation in the jffs2_1pass.c.

I also added the eraseblock size to the partition information to skip empty eraseblocks if we find more then 4k of free space.

The JFFS2 scanner is now fast enough to remove the spinning wheel so I #ifdef-ed it out.

I added watchdog calls in the long running loops.

The speed increasement was x10 on my board. I tested this for some days now and it works good for me.

regards Christian
