There were a few theoretical possibilities that the compiler might
optimize away DMA descriptor reads and/or writes and thus cause
synchronization problems with the hardware. Insert barriers where
we depend on reads/writes actually hitting memory.

* Cleaned up the CDS PCI Config Tables and added NULL entries to
the end
* Fixed PCIe LAWBAR assignemt to use the cpu-relative address
* Fixed 85xx PCI code to assign powar region sizes based on the
config values (rather than hard-coding them)
* Fixed the 8548 CDS PCI2 IO to once again have 0 as the base address

When bringing up u-boot on new boards, PHY support sometimes gets
neglected. Most PHYs don't really need any special support,
though. By adding a generic entry that always matches if nothing
else does, we can provide support for "unsupported" PHYs for the
tsec.
The generic PHY driver supports most PHYs, including gigabit.

Define CFG_DDR_SDRAM_CLK_CNTL for the MPC8349E-mITX and MPC8349E-mITX-GP.
This allows ddr->sdram_clk_cntl to be properly initialized. This is necessary
on some ITX boards, notably those with a revision 3.1 CPU.
Also change spd_sdram() in cpu/mpc83xx/spd_sdram.c to not write anything into
ddr->sdram_clk_cntl if CFG_DDR_SDRAM_CLK_CNTL is not defined.

Some device trees have a mac-address property, some have local-mac-address,

The PCI I/O space mapping for Freescale MPC8540ADS board was broken by commit
52c7a68b8d which failed to update the #define's
describing the local address window used for the PCI I/O space accesses -- fix
this and carry over the necessary changes into the MPC8560ADS code since the
PCI I/O space mapping was also broken for this board (by the earlier commit
087454609e). Add the comments clarifying how
the PCI I/O space must be mapped to all the MPC85xx board config. headers.

Rather than misleadingly define PVR_83xx as the specific type of 83xx
being built for, the PVR of each core revision is defined. checkcpu() now
prints the core that it detects, rather than aborting if it doesn't find
what it thinks it wants.

If a PCI IDE card happens to get a zero address assigned to it, the Linux IDE
core complains and IDE drivers fails to work. Also, assigning zero to a BAR
was illegal according to PCI 2.1 (the later revisions seem to have excluded the
sentence about "0" being considered an invalid address) -- so, use a reasonable
starting value of 0x1000 (that's what the most Linux archs are using).
Alternatively, one might have fixed the calls to pci_set_region() individually
(some code even seems to have taken care of this issue) but that would have
been a lot more work. :-)
