Ok, I reworded the comment to:

	/*
	 * There are two possible ways to start the phy. Let the hardware
	 * reset it properly or reset it a second time in software.
	 * Unfortunetly the phy needs some microseconds after reset to
	 * settle down.
	 * FIXME: Port support for the "phy-reset-post-delay" property to
	 *        barebox.
	 */
