synchronizing accesses with nand_base

[Ben Gamsa]

I've inherited some code that implements the chip interface for our 
board, and also implements *user_prot* interfaces for OTP access.  We 
ran into some problems that seem to be due to the fact that the OTP 
accesses can collide with regular filesystem accesses.  I noticed that 
the nand_base.c code uses a nand_get_device/nand_release_device for 
synchronization, but those routines appear to be private to that file. 
What is the proper way to add device-specific routines for OTP access 
while following proper synchronization procedures.

Thanks for any help.
