Hi Mr Rubini ...
I am writing a driver in which device port is mapped to CPLD and 8 bit data
bus is directly connected from processor to CPLD. Read write on CPLD memory
mapped (buffer/register) is required to control the device. This is now IO
mapped to processor.
I need to know whether i am right if i impliment like this :-
addr=ioremap(base_addr,size); // Remap to Mem mapped
address
out_8(addr) and in_8(addr);
