	      obvious reason.



    dtc

	Create flattend device tree blob object suitable for linking

	into vmlinux. Device tree blobs linked into vmlinux are placed

	in an init section in the image. Platform code *must* copy the

	blob to non-init memory prior to calling unflatten_device_tree().



	Example:

		#arch/x86/platform/ce4100/Makefile

		clean-files := *dtb.S



		DTC_FLAGS := -p 1024

		obj-y += foo.dtb.o



		$(obj)/%.dtb: $(src)/%.dts

EEPROMs (I2C)



Required properties:



  - compatible : should be "<manufacturer>,<type>"

		 If there is no specific driver for <manufacturer>, a generic

		 driver based on <type> is selected. Possible types are:

		 24c00, 24c01, 24c02, 24c04, 24c08, 24c16, 24c32, 24c64,

		 24c128, 24c256, 24c512, 24c1024, spd



  - reg : the I2C address of the EEPROM



Optional properties:



  - pagesize : the length of the pagesize for writing. Please consult the

               manual of your device, that value varies a lot. A wrong value

	       may result in data loss! If not specified, a safety value of

	       '1' is used which will be very slow.



  - read-only: this parameterless property disables writes to the eeprom



Example:



eeprom@52 {

	compatible = "atmel,24c32";

	reg = <0x52>;

	pagesize = <32>;

};
