On some 32-bit sparcs, the OF runs in non-cached memory.
Sucking in the OF device tree take a signficant amount of the boot time on such systems.
And these changes are going to make it even slower.
Please just put a wrapper around dp->name or whatever and use that, instead of making more get property OF calls which can be very expensive.
