The reason for this was that the sum and name were both being stored in the
object header (on NAND). This meant that if these got out of step with
eachother, for whatever reason, it would no longer be possible to find the
file. Instead yaffs now calculates the sum from the name at scan time, so
they can no longer get out of step. I kept the field in the ObjectHeader, but
renamed it sum_noLongerUsed. Thus, old mkyaffsimage is still binary
compatable with the changed scanning system.

I have fixed and updated this in cvs.

Thanx to Sharath for pointing this out.
