So there was a comment from Richard on the original patch that got
mangled so it did not even have a subject line.
The original intent for this patch was to make it possible to setup the
simulator with the same parameters as some real hardware.
That is the command "mtdinfo /dev/mtdX" would show the same on the
simulator as the real hardware.
Just to make sure: nandsim simulates a given NAND chip but the simulated
NAND flash controller will always be different.
Think of ECC layout.
Yes but ecc layout is generally not visible to layers on top of MTD in
the same way that the smallest writeable block size(sub page) is. It
just feels strange that the simulator could not simulate lack of subpage
writes as it do exist on quite a few nand controllers. And in real life
there is always going to be a controller in front of the nand chip so
any simulator really should take that into account.
