2c40acd352 sbc8548: get_clock_freq is not valid for this board
The get_clock_freq() comes from freescale/common/cadmus.c and is
only valid for the CDS based 85xx reference platforms.  It would
be nice if we could read the 33 vs. 66MHz status somehow, but in
the meantime, tie it to CONFIG_SYS_CLK_FREQ like all the other
non-CDS boards do.

7b1f1399e8 sbc8548: delete unused MPC8548CDS info carried over from port
There are a couple defines and PCI bridge quirks related to the PCI
backplane of the MPC8548CDS that have no meaning in the context of
the port to the sbc8548 board, so delete them.

Also, the form factor of the sbc8548 is a standalone board with a
single PCI-X and a single PCI-e slot.  That pretty much guarantees
that it will never be a PCI agent itself, so the host/agent and root
complex/end node distinctions have been removed.

Similarly, since there is no physical connector mapping to PCI2, so
all references of PCI2 in the board support files have been removed
as well.

bd42bbb858 sbc8548: replace README with completely new document
The previous README.sbc8548 was pretty much content-free. Replace
it with something that actually gives the end user some relevant
hardware details, and also lists the u-boot configuration choices.

Also in the cosmetic department, fix the bogus line in the Makefile
that was carried over from the SBC8560 Makefile, and the typo in
the sbc8548.c copyright.

3e7b6c1f2d ppc/8xxx: Refactor code to determine if PCI is enabled & agent/host
Refactor the code into a simple bitmask lookup table that determines if
a given PCI controller is enabled and if its in host/root-complex or
agent/end-point mode.

Each processor in the PQ3/MPC86xx family specified different encodings
for the cfg_host_agt[] and cfg_IO_ports[] boot strapping signals.

a5d212a263 mpc8xxx: LCRR[CLKDIV] is sometimes five bits
On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits
instead of four.

In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems.  It
should be safe as the fifth bit was defined as reserved and set to 0.

Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

a2cd50ed6e 85xx: Add CPU 2 errata workaround to all 8548 boards
All mpc8548-based boards should implement the suggested workaround
to CPU 2 errata. Without the workaround, its possible for the
8548's core to hang while executing a msync or mbar 0 instruction
and a snoopable transaction from an I/O master tagged to make
quick forward progress is present.

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.

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.
