7e2ec1de1d mpc83xx: MPC837XEMDS: Initialize SerDes before negating PCIE reset signal
The SerDes initialization should be finished before negating the reset
signal according to the reference manual. This isn't an issue on real
hardware, but we'd better stick to the specifications anyway.

8b34557c54 mpc83xx: Add PCI-E support for MPC837XEMDS boards
MPC837XEMDS boards can support PCI-E via "PCI-E riser card". The card
provides two PCI-E (x2) ports. Though, only one port can be used in x2
mode. Two ports can function simultaneously in x1 mode.

PCI-E x1/x2 modes can be switched via "pex_x2" environment variable.

3bf1be3c0c mpc83xx: add support for switching between USB Host/Function for MPC837XEMDS
With this patch u-boot can fixup the dr_mode and phy_type properties
for the Dual-Role USB controller.

While at it, also remove #ifdefs around includes, they are not needed.

00f7bbae92 mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boards
The MPC837xE-MDS board's CPLD can auto-detect if the board is on the PIB,
standalone or acting as a PCI agent. User's Guide says:

- When the CPLD recognizes its location on the PIB it automatically
  configures RCW to the PCI Host.
- If the CPLD fails to recognize its location then it is automatically
  configured as an Agent and the PCI is configured to an external arbiter.

This sounds good. Though in the standalone setup the CPLD sets PCI_HOST
flag (it's ok, we can't act as PCI agents since we receive CLKIN, not
PCICLK), but the CPLD doesn't set the ARBITER_ENABLE flag, and without
any arbiter bad things will happen (here the board hangs during any config
space reads).

In this situation we must disable the PCI. And in case of anybody really
want to use an external arbiter, we provide "pci_external_aribter"
environment variable.

1da83a63d8 mpc83xx: add SGMII riser module support for the MPC8378E-MDS boards
This involves configuring the SerDes and fixing up the flags and
PHY addresses for the TSECs.

For Linux we also fix up the device tree.

55c531984d mpc83xx: fix serdes setup for the MPC8378E boards
MPC837xE specs says that SerDes1 has:

— Two lanes running x1 SGMII at 1.25 Gbps;
— Two lanes running x1 SATA at 1.5 or 3.0 Gbps.

And for SerDes2:

— Two lanes running x1 PCI Express at 2.5 Gbps;
— One lane running x2 PCI Express at 2.5 Gbps;
— Two lanes running x1 SATA at 1.5 or 3.0 Gbps.

The spec also explicitly states that PEX options are not valid for
the SD1.

Nevertheless MPC8378 RDB and MDS boards configure the SD1 for PEX,
which is wrong to do.

d26154c9a6 mpc83xx: spd_sdram: fix ddr sdram base address assignment bug
The spd_dram code shifts the base address, then masks 20 bits, but
forgets to shift the base address back. Fix this by just masking the
base address correctly.

Found this bug while trying to relocate a DDR memory at the base != 0.

9973e3c614 Change initdram() return type to phys_size_t
This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory.  phys_size_t is defined as an unsigned long on almost
all current platforms.

This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram).  It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.

Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
MPC8641HPCN.

a30a549a35 Remove erroneous or extra spd.h #includers.
Many of the spd.h #includers don't need it,
and wanted to have spd_sdram() declared instead.
Since they didn't get that, some also had open
coded extern declarations of it instead or as well.
Fix it all up by using spd_sdram.h where needed.
