Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Clean up Makefile, and drop a lot of the config.mk files on the way.
We now also automatically pick all boards that are listed in
boards.cfg (and with all configurations), so we can drop the redundant

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.
Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

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.

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.

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.

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.
