Compact Flash Card problem

I am trying to implemnent the CF Card in my Nios system. But there is not any reference about it. Should I write a driver for it and prepare the subroutine? or there is already one? http:...

In the source code for ideutils.c There is the following....

# define ctl_base (int*)CF_CTL_BASE# define ctl_irq (int)CF_CTL_IRQ# define ide_base (int*)CF_IDE_BASE# define ide_irq (int)CF_IDE_IRQ

whereas in the documentation it says simple...

# define ide_base <SOPC-name>_IDE_BASE# define ide_irq <SOPC-name>_IDE_IRQ# define ctl_base <SOPC-name>_CTL_BASE# define ctl_irq <SOPC-name>_CTL_IRQ

why the (int*) cast?
