389e4721e9 Make MPC85xx LAW handling and reset routines aware of the MPC8548 variant.
Inspired by discussion with Alexey V Fedorov on freebsd-powerpc@.

25c22eb425 Extend and improve MPC85XX Local Bus management.
- Make LBC resources management self-contained: introduce explicit LBC
  resources definition (much like the OCP), provide dedicated rman for LB mem
  space.

- Full configuration of an LB chip select device: program LAW and BR/OR, map
  into KVA, handle all LB attributes (bus width, machine select, ecc,
  write protect etc).

- Factor out LAW manipulation routines into shared code, adjust OCP area
  accordingly.

- Other LBC fixes and clean-ups.

- Simplify SVR version subfield handling
- Adjust OCP

bd616bc87e Assign 0xff800000-0xffffffff to the LBC controller. That's where
the NOR flash lives by default.

6937461ee9 Remove mfsvr():
o  The function is defined unconditionally but depends on SPR_SVR,
   which is defined conditionally.
o  spr.h defines mfspr() and mtspr(), which is no worse to use.

8464af7949 Improve handling of Local Access Windows on MPC85xx systems:
- detect number of LAWs in run time and initalize accordingly
- introduce decode windows target IDs used in MPC8572
- other minor updates

ecb1ab1761 Obtain TSEC h/w address from the parent bus (OCP) and not rely blindly on what
might be currently programmed into the registers.

Underlying firmware (U-Boot) would typically program MAC address into the
first unit only, and others are left uninitialized. It is now possible to
retrieve and program MAC address for all units properly, provided they were
passed on in the bootinfo metadata.

27080415a2 Don't use in32() and out32() when writing to the CCSRBAR. The
in*() and out*() primitives should not be used, other than by
ISA drivers. In this case they were used for memory-mapped I/O
and were not even used in the spirit of the primitives.

d6f5929710 Add support for the BUS_CONFIG_INTR() method to the platform and to
openpic(4). Make use of it in ocpbus(4). On the MPC85xxCDS, IRQ0:4
are active-low.

4fa8db5df0 o We don't have to keep track of the PIC, nor do we have to make sure
it's probed first. The PowerPC platform code deals with everything.
   As such, probe devices in order of their location in the memory map.
o  Refactor the ocpbus_alloc_resource for readability and make sure we
   set the RID in the resource as per the new convention.

6b7ba54456 Initial support for Freescale PowerQUICC III MPC85xx system-on-chip family.
The PQ3 is a high performance integrated communications processing system
based on the e500 core, which is an embedded RISC processor that implements
the 32-bit Book E definition of the PowerPC architecture. For details refer
to: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC8555E

This port was tested and successfully run on the following members of the PQ3
family: MPC8533, MPC8541, MPC8548, MPC8555.

The following major integrated peripherals are supported:

  * On-chip peripherals bus
  * OpenPIC interrupt controller
  * UART
  * Ethernet (TSEC)
  * Host/PCI bridge
  * QUICC engine (SCC functionality)

This commit brings the main functionality and will be followed by individual
drivers that are logically separate from this base.
