Not necessarily. It depends on the architecture.
Having 32 address lines gives the ability to address
a
4G address space. Where it is mapped to depends on
the
hardware.
ioaddr = ioremap(physical_addr, Len);know...
ioaddr should be of type - unsigned long.
oky...but, ioremap() returns type "void *"
So, should we type cast ...
void * is a generic type. It cannot be used
directly.
It is useful to pass addresses (that can represent
anything). You will need to typecast it to use it.

PS: Not to offend you, but this attitude is really
irritating. ILUGC is
not a technical support center.
No offence, but, if you do not wish to reply, please
ignore the e-mail. But, don't discourage a person
from
asking questions. I don't see why ILUGC cannot be a
technical support center. It is a great place to
learn
and provide technical help :)
