Accessing an MTD device from kernel space

[Eisenhut, Daniel (MED)]

To list,

I've successfully setup MTD devices for our NOR flash chips and
everything is working great from userspace.  But I have a need to access
the NOR flash from within kernelspace, such as in a /proc entry.

What is the best way to access the flash from within the kernel?  The
only way I've be able to so far is to just dereference a pointer
pointing to the flash address.  But this creates two issues (that I know
about):

1. A race condition between my proc entry that reads the flash and
another process using the MTD device.

2. The MTD device does not always leave the flash chip in read mode.

Is there anything setup in the current MTD code to allow access from
within the kernel?

Thanks...
