Is it acceptable to do direct port I/O through driver for I/O port accesses (other than the PCI bus accesses). I still couldn't figure out the solution for this kind of problem.
Ahh - for enabling flash writes. Well - the alternative is to have all flash enabling code and logic within the kernel driver but that's not very attractive.
Do you know if the IO can be limited to just a few explicitly allowed ports?
Well, that shouldn't be a problem. I mean it can be easily implemented in the driver. But, I need to know which I/O address range that would be ;-). All I know in detail right now is Winbond_I/O_chip-specific because I've only been working with it.
