Erratum NMG_DDR120 (DDR19 in MPC8548 errata document) applies to some
early version silicons. The default settings of the DDR IO receiver
biasing may not work at cold temperature. When a failure occurs,
a DDR input latches an incorrect value. The workaround will set the
receiver to an acceptable bias point.

1. Temporarily map CONFIG_SYS_MONITOR_BASE to the 1M

Unified DDR driver is maintained for better performance, robustness and bug
fixes. Upgrading to use unified DDR driver for MPC83xx takes advantage of
overall improvement. It requires changes for board files to customize
platform-dependent parameters.

To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx
in the header file. No more boards will be accepted without such definition.

Note: the workaround for erratum DDR6 for the very old MPC834x Rev 1.0/1.1
and MPC8360 Rev 1.1/1.2 parts is not migrated to unified driver.

We currently support 4 SoC/Boards from the P-Series of QorIQ SoCs that
are based on the 'CoreNet' Architecture: P2041RDB, P3041DS, P4080DS, and
P5020DS.  There is a significant amount of commonality shared between
these boards that we can refactor into common code:

* Initial LAW setup
* Initial TLB setup
* PCI setup

We start by moving the shared code between P3041DS, P4080DS, and P5020DS
into a common directory to be shared with other P-Series CoreNet boards.

Add support for RGMII, SGMII, and XAUI (10Gb) Ethernet on P3041DS &
P5020DS ("Hydra").

The lane_to_slot[] array is initialized dynamically, since board switches
can be used to control the muxing of SERDES lanes to slots.

The BRDCFG1 PIXIS register is used to route the MII bus to the appropriate
slot.  The SERDES configuration is queried to help determine the routing
between MACs and slot/phy combination.

If a XAUI card is inserted, muxing for that card is enabled and never
turned off.  The PHY address for the 10G XAUI card depends on the slot in
which it's inserted.  If it's in slot 1, the address is 4.  If it's in
slot 2, the address is 0.

Update the MDIO routing in the P3041DS and P5020DS device trees based on
the board-level muxing.  The SERDES configuration determines which
SGMII/XGMII boards are located in which slots, and so the MDIO bus needs
to be muxed correctly whenever talking to a PHY connected to any Fman MAC.
The Fman Ethernet nodes in the device tree also need to be routed to the
correct PHYs.

Add support for RGMII, SGMII, and XAUI (10Gb) Ethernet on P4080DS.

The board supports add-on cards for SGMII and XAUI functionality.  Which
slots on the board these cards are in is a function of the SERDES option
selected and muxes on the board.

Additionally because of the high-configurablity which MDIO bus one is
connected to is "selected" via an FPGA register.  We create dummy MDIO
bus for the phy layer and hide the mux manipulation in this dummy layer.

Add fman fdt helper function in board common code it'll be used by several
freescale boards that do various muxing of the MDIO signals based on which
controller/interface one is trying to talk to.

The Frame Manager (FMan) on QorIQ SoCs with DPAA (datapath acceleration
architecture) is the ethernet contoller block.  Normally it is utilized
via Queue Manager (Qman) and Buffer Manager (Bman).  However for boot
usage the FMan supports a mode similar to QE or CPM ethernet collers
called Independent mode.

Additionally the FMan block supports multiple 1g and 10g interfaces as a
single entity in the system rather than each controller being managed
uniquely.  This means we have to initialize all of Fman regardless of
the number of interfaces we utilize.

Different SoCs support different combinations of the number of FMan as
well as the number of 1g & 10g interfaces support per Fman.

We add support for the following SoCs:
 * P1023 - 1 Fman, 2x1g
 * P4080 - 2 Fman, each Fman has 4x1g and 1x10g
 * P204x/P3041/P5020 - 1 Fman, 5x1g, 1x10g
