r233822:
Remove useless and wrong piece of code in fdt_get_range() which i
overwrites passed phandle_t node. Modify debug printf in fdt_reg_to_rl()
to be consistent (that is, print start and end *virtual* addresses).
r230560:
Handle "ranges;"
Make fdt_reg_to_rl() responsible for mapping the device memory, instead
on just hoping that there's only one simplebus, and using fdt_immr_va as
the base VA.
r230315
Add a function to get the PA from range, instead of (ab)using
fdt_immr_pa, and use it for the UART driver
into partitions.
Partitions are created based on data in dts file which are
extracted and interpreted by slicer.

This lets specify whereabouts of the parent PHY for a given MAC node
(and get rid of ugly kludges in mge(4) and tsec(4)).

o fdtbus(4) - the main abstract bus driver for all FDT-compliant systems. This
is a direct replacement for the many incompatible bus drivers grouping
integrated peripherals on embedded platforms (like obio(4), ocpbus(4) etc.)
o simplebus(4) - bus driver representing ePAPR style 'simple-bus' node, which
is an umbrella device for most of the integrated peripherals on a typical
system-on-chip device.
o Other components (common routines library, PCI node processing helper
functions)
