I think the problem is that you need to use the pointer which ioremap() returns
to access the region you requested. It looks like you've assumed that ioremap()
will map it 1:1 which I don't think is the case.

i.e.

struct hw_regs *foo;

foo = (struct hw_regs *)ioremap(0xfc000000, <Size>);

foo->command = hw_reset;
...
