insl/outsl in parport_pc and !CONFIG_PCI

[Richard Zidlicky]

Hi,

How is that supposed to work on systems without PCI? For now I have
defined 

#define insl(port,buf,len)   isa_insb(port,buf,(len)<<2)
#define outsl(port,buf,len)  isa_outsb(port,buf,(len)<<2)

in asm-m68k/parport.h.

Bye
Richard

Tim, Fred,

Will 4 * inb() cycles have the same effect as 1 * inl() cycle for an EPP
mode read?

By the way, it's probably worth a check whether insl() is actually
faster than a loop doing inl() these days.  Guess I should do that :)

cheers,

4 inb() cycles on the same port, yes, I think so (but not on
successive ports).
