sys/sparc64/sparc64 ofw_machdep.c
Log:
Add function OF_decode_addr(). This function obtains the physical
address of the device identified by its phandle_t by traversing OFW's
device tree. The space and address returned by this function can
subsequently be passed to sparc64_fake_bustag() to construct a valid
tag and handle for use by the newbus I/O functions.
Use of this function is expected to be limited to pre-newbus access to
devices, such as consoles and keyboards.
