b88e42560b omap3: Configure RAM bank 0 if in SPL
OMAP3 relied on the memory config done by X-loader or Configuration Header. This
has to be reworked for the implementation of a SPL. This patch configures RAM
bank 0 if CONFIG_SPL_BUILD is set. Settings for Micron-RAM used by devkit8000

d29d17d7ba powerpc/mpc83xx: Migrate from spd_sdram to unified DDR driver
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.

other P-Series CoreNet platforms.

The only difference between P2041RDB & P3041DS/P4080DS/P5020DS is the
CPLD vs PIXIS FPGA which we can handle via some simple #ifdefs in the
TLB and LAW setup tables.

360275b362 powerpc/85xx: refactor common P-Series CoreNet files for FSL boards
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.

cba4614862 powerpc/hydra: Add ethernet support on P5020/P3041 DS 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.

Removed CONFIG_SYS_FMAN_FW as its not used anywhere.

2915609a91 powerpc/85xx: Add FMan ethernet support to P4080DS
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.

c916d7c914 powerpc/85xx: Add support for FMan ethernet in Independent mode
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

Flash. The code which programs the BA and AMASK is executed from L2-SRAM.

14aa71e660 powerpc/85xx: Add support for new P102x/P2020 RDB style boards
The following boards share a common design but with minor variations
between them:

P1020MSBG-PC
P1020RDB-PC
P1020UTM-PC
P1021RDB-PC
P1024RDB
P1025RDB
P2020RDB-PC

The P1020RDB-PC shares its roots in the existing P1020RDB board design,
however uses DDR3 instead of DDR2.
P2020RDB-PC differs from the P102x RDB-PC with 64-bit DDR and 100Mhz SYSCLK.

Key features on these boards include:
* DDR3
* NOR flash
* NAND flash (on RDB's only)
* SPI flash (on RDB's only)
* SDHC/MMC card slot
* VSC7385 Ethernet switch (on P1020MBG, P1020RDB, & P1021RDB)
* PCIE slot and mini-PCIE slots

As these boards use soldered DDR chips not regular DIMMs, an on-board EEPROM
is used to store SPD data. In case of absent or corrupted SPD, falling back
to timing data embedded in the source code will be used. Raw timing data is
extracted from DDR chip datasheet. Different speeds of DDR are supported
with this approach. ODT option is forced to fit this set of boards, again
because they don't have regular DIMMs.

CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS is defined as 5ms to meet
specification for writing timing.

VSC firmware Address is defined by default in config file for eTSEC1.

SD width is based off DIP switch. DIP switch is detected on the
board by reading i2c bus and setting the appropriate mux values.

Some boards have QE module in the silicon (P1021 and P1025). QE and eLBC
have pins multiplexing. QE function needs to be disabled to access Nor Flash
and CPLD. QE-UEC and QE-UART can be enabled for linux kernel by setting "qe"
in hwconfig. In addition, QE-UEC and QE-TDM also have pins multiplexing, to
enable QE-TDM for linux kernel, set "qe;tdm" in hwconfig. Syntax is as below

'setenv hwconfig qe' to enable QE UEC/UART and disable Nor-Flash/CPLD.
'setenv hwconfig 'qe;tdm'' to enalbe QE TDM and disable Nor-Flash/CPLD.

6ca88b0958 powerpc/85xx: relocate CCSR before creating the initial RAM area
Before main memory (DDR) is initialized, the on-chip L1 cache is used as a
memory area for the stack and the global data (gd_t) structure.  This is
called the initial RAM area, or initram.  The L1 cache is locked and the TLBs
point to a non-existent address (so that there's no chance it will overlap
main memory or any device).  The L1 cache is also configured not to write
out to memory or the L2 cache, so everything stays in the L1 cache.

One of the things we might do while running out of initram is relocate CCSR.
On reset, CCSR is typically located at some high 32-bit address, like
0xfe000000, and this may not be the best place for CCSR.  For example, on
36-bit systems, CCSR is relocated to 0xffe000000, near the top of 36-bit
memory space.

On some future Freescale SOCs, the L1 cache will be forced to write to the
backing store, so we can no longer have the TLBs point to non-existent address.
Instead, we will point the TLBs to an unused area in CCSR.  In order for this
technique to work, CCSR needs to be relocated before the initram memory is
enabled.

Unlike the original CCSR relocation code in cpu_init_early_f(), the TLBs
we create now for relocating CCSR are deleted after the relocation is finished.
cpu_init_early_f() will still need to create a TLB for CCSR (at the new
location) for normal U-Boot purposes.  This is done to keep the impact to
existing U-Boot code minimal and to better isolate the CCSR relocation code.

e46fedfeb2 powerpc/85xx: introduce and document CONFIG_SYS_CCSRBAR macros
Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW
macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS.
This is necessary for the assembly-language code that relocates CCSR, since
the assembler does not understand 64-bit constants.

CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the
CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it
should not be defined in a board header file.  Similarly,
CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so
it should also not be defined in the board header file.

CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that
CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT,
and so CCSR will not be relocated.

Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot
builds (e.g. NAND) are required to relocate CCSR only during the last stage
(i.e. the "real" U-Boot).  All other stages should define
CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated.

README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.
