This patch adds the Denali SDRAM controller definitions to "ppc440.h".
It also fixes two typos in the definitions, so the board-specific
"sdram.h" files containing these definitions are also fixed to avoid
compiler warnings.

On Sequoia & LWMON5 the virtual address of the POST cache test is now
moved to a bigger address. This enables usage of more memory on those
boards.

Now the cpu node setup ("timebase-frequency" and "clock-frequency") is
without using the absolute path to the cpu node. This makes it possible
to use this U-Boot version with both versions of cpu-node naming
"cpu@0" and the former "PowerPC,440EPx@0".

When using dhcp/bootp the "netmask" environment variable is not
set because CONFIG_BOOTP_SUBNETMASK is not defined. But usually this is
desireable, so the following patch adds this this option to the board
config.

This patch enables the hardware-fix for the PCI/DMA errata's 19+22 by
setting the FIXD bit in the SDR0_MFR register. Here a description of the
symptoms:
Problem Description
------------------------------
If a DMA is performed between memory and PCI with the DMA 1 Controller
using prefetch, and as a result uses a special purpose buffer selected by
the PCIXn Bridge Options 1 Register (PCIXn_BRDGOPT1[RBP7] - bits 31-29),
the first part of the transfer sequence is performed twice. The
PPC440SPe PCI Controller requests more data than was needed such that in
the case of enforce memory protection, a host CPU exception can occur.
No data is corrupted, because data transfer is stopped in the PCI
Controller. Prefetch enable is specified by setting DMA Configuration
Register (I2O0_DMAx_CFG[DXEPD] - bit 31) to 0.
Behavior that may be observed in a running system
---------------------------------------------------------------------------
1. DMA performance is decreased because of the double access on the PCI bus
interface.
2. If an illegal access to some address on the PCI bus is detected at the
system level, a machine check or similar system error may occur.
Workarounds Available
----------------------------------
1. Do not program prefetch. Note that a prefetch command cannot be programmed
without selecting a special purpose buffer.
2. To avoid crossing a physical boundary of the PCI slave device, add 512
bytes of address to the PCI address range.

Added the following fdt fixup helpers:
* do_fixup_by_prop{_u32} - Find matching nodes by property name/value
* do_fixup_by_compat{_u32} - Find matching nodes by compat
The _u32 variants work the same only the property they are setting
is know to be a 32-bit integer instead of a byte buffer.

Moved the generic fixup handling code out of cpu/mpc5xxx and cpu/mpc8260

Removed:
fdt_node_is_compatible
fdt_find_node_by_type
fdt_find_compatible_node
To ease merge of newer libfdt as we aren't using them anywhere at this time.
Also moved fdt_find_and_setprop out of libfdt into fdt_support.c for the same
reason.

Ugh. I *hate* to back this change out, but these compiler flags don't
work for relocation on all versions of GCC. I've not been able to
reproduce the environment in my setup (and hence, not been able to
find a combination that *does* work), so I've got no choice but to go
back to the old gcc flags and linker script.

Although mips_io_port_base is currently a part of IDE command, it is quite
fundamental for MIPS I/O port access such as in[bwl] and out[bwl]. So move
it to MIPS general part, and introduce `set_io_port_base()' from Linux.
This patch is triggered by multiple definition of `mips_io_port_base' build
error on gth2 (and tb0229 also needs this fix.)
