MEMGETREGIONCOUNT ioctl

[Jitendra Jain]

Hi All,
 
I am trying to get some information regarding my NAND device on board
through the MEMGETREGIONCOUNT and the MEMGETREGIONINFO ioctls. What
troubles me is that the mtd/util application "flash_info" also doesnt
come to my rescue.
 
As per the driver, the MEMGETREGIONCOUNT returns the parameter
numeraseregions, which is meant to signify if the flash erase size is
same throughout or whether it has variable sized sectors (which is found
on NOR flash devices). Why does the util denote that number as number of
erase regions ??
 
Next, the MEMGETREGIONINFO seems to copy arguments from User to the
kernel which I dont understand. This is meant to give the User
information so, it ought to be copy_to_user.
 
Please excuse me if I am wrong on both the above accounts, but i would
be glad if anybody would let me know about that...
 
Thanx,

Regards
Jitendra Jain,
