So... you're now fine with isa_io_base?
no, I'd like to get rid of it and deprecate the use of inb/outb
interfaces on power.
Our Maple systems *have* an ISA bus. They do. It contains serial,
NVRAM,
and the RTC. I don't understand why you want to pretend they don't.
I don't care what bus the device is on, just its address, and code
exists to access the device that way.
I see no reason to simulate an instruction from another architecture
(inb/outb).
If the 16550 was on the system without an ISA then inb/outb would be
useless.
I'm proposing we use readb/writeb exclusively.
