Since QEMU actually has this device I tried to add it, but not sure
where is it located.
In sun4u.c it's initialized like this:
nvram = m48t59_init_isa(isa_bus, 0x0074, NVRAM_SIZE, 59);
Is 0x74 the offset to the ISA bus? Then it's wired not as on Ultra-5:
Here it looks like it had to be aligned to a beginning of a page,
which makes sense because of the large size...
So, where QEMU's 0x74 are coming from?
It's the I/O port used by PPC. Looking at the reg, it should be using
MMIO at address 0 instead.
