[ELDK] Userland memory access

Hello,

I connected an external SRAM to my TQM885D module.
In the driver I'm writing, with the virtual address returned by ioremap(), I can access the memory locations with readb/writeb functions and also with direct access.

It's possible to map this kernel virtual space also in a user land process?

Best regards,

Luigi
