Robert P.J. Day proposed to use the macro FIELD_SIZEOF in replace of code
that matches its definition.

It appears that in some cases, the sync word might not be recognized
by the hardware correctly.  If this happens, then attempting to read
from the port results in an unrecoverable error because of the design
of the FPGA core.  This patch updates the code to check the status of
the device before reading the IDCODE, in order to avoid entering this
unrecoverable state.  This patch also adds additional NOOP commands
into the sychronization sequence, which appears to be necessary to
avoid the condition on some hardware.

Both the buffer-based and fifo-based icap cores have a status

main driver along with some masks for the differnet bits.

All this code is needed to properly initialize the 460EX PCIe host
bridge(s). We re-initialize all ports again, even though this has been done
in the bootloader (U-Boot) before. This way we make sure, that we always
run the latest init code in Linux and don't depend on code versions from
U-Boot.

Unfortunately all IBM/AMCC chips currently supported in this PCIe driver need
a different reset-/init-sequence.

This patch alters the bootwrapper for a number of machines (roubhly
all 4xx based cuboot or treeboot platforms) to use aliases instead of
the linux,network-index hack to work out which MAC address to attach
to which ethernet device node.

The now obsolete linux,network-index properties are removed from the
corresponding device trees.  This won't break backwards compatiblity,
because in cases where this fixup code is relevant, the device tree is
part of the kernel image.

The references to linux,network-index are removed from
booting-without-of.txt.  Not only is it now deprecated, but as a hack
applicable only when the device tree blob and fixup code were in the
same image, this property never belonged in booting-without-of.txt
which describes the interface between the kernel and firmware or
bootloaders which produce a device tree.  By the time the device tree
reaches the kernel, all the MAC addresses must be fully filled in.
