I am not sure if there is any for arm. Can you pl. point me any code
snippet (perhaps arch specific) example?

BTW: I am thinking to change io_base to word_size {arch size aligned} in v2
patch revision and By doing that we don't need care for ifdefs. Currently
uin32_t hold good for io;s ranging from 0 to 65535.

Wanted to keep something like below

unsigned long io_base;

for 32 bit case - 4 byte
for 64 bit case - 8 byte.

Does that make sense?
