I'm bored of arguing about suffixes. Let's talk MTD.
When using mtdram device, is it necessary to fill the device with 0xff
first? Suppose I make a 8388608 byte mtdram device and then my
file.jffs2 is only 6000000 bytes long. Need I fill the rest of the
device with 0xff before mounting? Should I fill with zeros (there was
an unanswered question on this subject 2005-Dec-14 on the list).
What about if I "reaload", eg. umount the device, and want to copy a new
file.jffs2 image into it? Or should the driver be reloaded in this case?
