Hi,
> Hopefully there are examples of passing these values through ACPI.
Are you suggesting here to look at the ide-acpi.c sourc file available as
part of the driver code? In my original post I mentioned that I have
modified the ide-generic.c source file to use the IO port addresses and IRQ
number that we used in the older kernel. Also, added code in the kernel
under arch/PowerPC/mm/init_32.c source to configure the addresses required
by the driver as IO ports. But the error I am getting still continues to
suggest that probably the required address range is still setup by the
kernel as IO ports.
How can we configure a set of virtual address as IO ports in the kernel
version 4.15.13?
Sachin
