v) Xilinx hwicap

Xilinx hwicap devices provide access to the configuration logic
of the FPGA through the Internal Configuration Access Port
(ICAP). The ICAP enables partial reconfiguration of the FPGA,
readback of the configuration information, and some control over
'warm boots' of the FPGA fabric.

Required properties:
- xlnx,family : The family of the FPGA, necessary since the
capabilities of the underlying ICAP hardware
differ between different families. May be
'virtex2p', 'virtex4', or 'virtex5'.

};

q) USB EHCI controllers

Required properties:
- compatible : should be "usb-ehci".
- reg : should contain at least address and length of the standard EHCI
register set for the device. Optional platform-dependent registers
(debug-port or other) can be also specified here, but only after
definition of standard EHCI registers.
- interrupts : one EHCI interrupt should be described here.
If device registers are implemented in big endian mode, the device
node should have "big-endian-regs" property.
If controller implementation operates with big endian descriptors,
"big-endian-desc" property should be specified.
If both big endian registers and descriptors are used by the controller
implementation, "big-endian" property can be specified instead of having
both "big-endian-regs" and "big-endian-desc".

Example (Sequoia 440EPx):
ehci@e0000300 {
compatible = "ibm,usb-ehci-440epx", "usb-ehci";
interrupt-parent = <&UIC0>;
interrupts = <1a 4>;
reg = <0 e0000300 90 0 e0000390 70>;
big-endian;
};


More devices will be defined as this spec matures.

help
This specifies the device tree source (.dts) file to be
compiled and included when building the bootwrapper. If a
relative filename is given, then it will be relative to
arch/powerpc/boot/dts. If you are not using the bootwrapper,
or do not need to build a dts into the bootwrapper, this
field is ignored.

For example, this is required when building a cuImage target
for an older U-Boot, which cannot pass a device tree itself.
Such a kernel will not work with a newer U-Boot that tries to
pass a device tree (unless you tell it not to). If your U-Boot
does not mention a device tree in "help bootm", then use the
cuImage target and specify a device tree here. Otherwise, use
the uImage target and leave this field blank.
