According to the open firmware standard, finddevice call has to return
a phandle with value of -1 in case of error.
This commit is to:
- Fix the FDT implementation of this interface (ofw_fdt_finddevice) to
return (phandle_t)-1 in case of error, instead of 0 as it does now.
- Fix up the callers of OF_finddevice() to compare the return value with
-1 instead of 0 to check for errors.
- Since phandle_t is unsigned, the return value of OF_finddevice should
be checked with '== -1' rather than '<= 0' or '> 0', fix up these cases
as well.

of range.
- Fix various places that set rm_end incorrectly (to ~0 or ~0u instead of
~0ul).
- To preserve existing behavior, change rman_init() to set rm_start and
rm_end to allow managing the full range (0 to ~0ul) if they are not set by
the caller when rman_init() is called.
that represents the host controller. This makes the FDT PCI support
working an a bare-bones manner. This needs a lot more work, of which
the beginning are at the end of the file, compiled-out with #if 0.
The intend being that both the Marvell PCIE and Freescale PCI/PCIX/PCIE
duplicate the same platform-independent domain initialization, that
should be moved into an unified implementation in the FDT code. Handling
of resources requires help from the platform. A unified implementation
allows us to properly support PCI devices listed in the device tree and
configured according to the device tree specification.

The following systems are affected:
- MPC8555CDS
- MPC8572DS
This overhaul covers the following major changes:
- All integrated peripherals drivers for Freescale MPC85XX SoC, which are
currently in the FreeBSD source tree are reworked and adjusted so they
derive config data out of the device tree blob (instead of hard coded /
tabelarized values).
- This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC,
QUICC, UART, CFI.
- Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire
ocpbus(4) driver, which was based on hard-coded config data.
Note that world for these platforms has to be built WITH_FDT.

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)
