hi,
I want build an application that requires the exact memory address 
(for LCD display). I use ioremap to achieve that. However, when i 
try to compile the file, i get the following error.

implicit declaration of ioremap
and hence
unreferenced ioremap

I assume that this is becuase I can use ioremap only in kernel 
mode. I have tried using ioperm and iopl, but these work only on 
intel architecure and my platform does not support this. Nor do i 
have the device file /dev/port for my platform.

Is there are any way, I can access and set the memory directly in 
the user(application) mode ? I do want to avoid building a driver 
and recompiling with the kernel.

The source code is as simple as
#include<asm/io.h>
void main()
{
  ioremap(0x10000,100);
}

Thanks and regards,
Rahul Patil
