Kumar Gala a09b9b68d4 powerpc/8xxx: Refactor SRIO initialization into common code
Moved the SRIO init out of corenet_ds and into common code for
8xxx/QorIQ processors that have SRIO.  We mimic what we do with PCIe
controllers for SRIO.

We utilize the fact that SRIO is over serdes to determine if its
configured or not and thus can setup the LAWs needed for it dynamically.

We additionally update the device tree (to remove the SRIO nodes) if the
board doesn't have SRIO enabled.

Introduced the following standard defines for board config.h:

CONFIG_SYS_SRIO - Chip has SRIO or not
CONFIG_SRIO1 - Board has SRIO 1 port available
CONFIG_SRIO2 - Board has SRIO 2 port available

(where 'n' is the port #)
CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot
CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup)
CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup)

[ These mimic what we have for PCI and PCIe controllers ]

Peter Tyser 213ac73e2c fsl_pci: Update PCIe boot ouput
This change does the following:
- Adds printing of negotiated link width.  This information can be
  useful when debugging PCIe issues.
- Makes it optional for boards to implement board_serdes_name().
  Previously boards that did not implement it would print unsightly
  output such as "PCIE1: Connected to <NULL>..."
- Rewords the PCIe boot output to reduce line length and to make it
  clear that the "base address XYZ" value refers to the base address of
  the internal processor PCIe registers and not a standard PCI BAR
  value.
- Changes "PCIE" output to the standard "PCIe"

Before change:
PCIE1: connected to <NULL> as Root Complex (base addr ef008000)
  01:00.0     - 10b5:8518 - Bridge device
   02:01.0    - 10b5:8518 - Bridge device
   02:02.0    - 10b5:8518 - Bridge device
   02:03.0    - 10b5:8518 - Bridge device
PCIE1: Bus 00 - 05
PCIE2: connected to <NULL> as Endpoint (base addr ef009000)
PCIE2: Bus 06 - 06

After change:
PCIe1: Root Complex of PEX8518 Switch, x4, regs @ 0xef008000
  01:00.0     - 10b5:8518 - Bridge device
   02:01.0    - 10b5:8518 - Bridge device
   02:02.0    - 10b5:8518 - Bridge device

Kumar Gala a4aafcc990 powerpc/fsl-pci: Add generic code to setup PCIe controllers
Since all the PCIe controllers are connected over SERDES on the SoCs we
can utilize is_serdes_configured() to determine if a controller is
enabled.  After which we can setup the ATMUs and LAWs for the controller
in a common fashion and allow board code to specify what the controller
is connected to for reporting reasons.

We also provide a per controller (rather than all) for some systems that
may have special requirements.

Finally, we refactor the code used by the P1022DS to utilize the new
generic code.

Kumar Gala 3a0e3c27a5 powerpc/fsl-pci: Determine pci_controller based on cfg addr for dts fixup
Previously we passed in a specifically named struct pci_controller to
determine if we had setup the particular PCI bus.  Now we can search for
the struct so we dont have to depend on the name or the struct being
statically allocated.

Introduced new find_hose_by_cfg_addr() to get back a pci_controller struct
back by searching for it means we can do things like dynamically allocate
them or not have to expose the static structures to all users.

Becky Bruce 38dba0c2ff mpc85xx boards: initdram() cleanup/bugfix
Correct initdram to use phys_size_t to represent the size of
dram; instead of changing this all over the place, and correcting
all the other random errors I've noticed, create a
common initdram that is used by all non-corenet 85xx parts.  Most
of the initdram() functions were identical, with 2 common differences:

1) DDR tlbs for the fixed_sdram case were set up in initdram() on
some boards, and were part of the tlb_table on others.  I have
changed them all over to the initdram() method - we shouldn't
be accessing dram before this point so they don't need to be
done sooner, and this seems cleaner.

2) Parts that require the DDR11 erratum workaround had different
implementations - I have adopted the version from the Freescale
errata document.  It also looks like some of the versions were
buggy, and, depending on timing, could have resulted in the
DDR controller being disabled.  This seems bad.

The xpedite boards had a common/fsl_8xxx_ddr.c; with this
change only the 517 board uses this so I have moved the ddr code
into that board's directory in xpedite517x.c

Becky Bruce 6b1ef2a6a5 mpc85xx/tlb.c: Allow platforms to specify wimge bits
Some platforms might want to override the default wimge=0 for
DDR.  Add CONFIG_SYS_PPC_DDR_WIMGE for those platforms to use.
This will initially only be used by TQM85xx, but could be
useful for other boards or testing going forward.  Note that
the name of this define is not 85xx-specific.  WIMGE is a
fairly universal concept, so any ppc platforms that require
different WIMGE settings for DDR can use the same #define.

Patch "Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value"
(sha1: 25ddd1fb0a)

Microblaze configs used 0x40(128) because this place also contained
board info structure which lies on the top of ram.

U-Boot is placed to the top of the ram (for example 0xd7ffffff)
and bd structure was moved out of ram.

This patch is fixing this scheme with GENERATED_BD_INFO_SIZE
which swap global data and board info structures.

For example:
Current: gd 0xd7ffffc0, bd 0xd8000000
