a question on "iowrite32()"

[Ming Liu]

Dear Arnd,

So if I am correct, your suggestion is to use iowrite32be() in my device 
driver, right? However, I cannot find such a function defined in my 2.6.10 
kernel. Isn't iowrite32be() a standard IO function like iowrite32(), or 
there is a patch to export this function?

Thanks for your information.
