 Features required for every CPU:

+@section time_keeping Time keeping
+
+In U-Boot-v2 we are using the clocksource mechanism from the Linux Kernel.
+This makes it fairly easy to add timer functionality for a new board or
+architecture.
+
+Apart from initialization there is only one function to be registerd:
+clocksource_read(). This function returns the current value of a free running
+counter. Other functions like udelay() and get_time_ns() are derived from this
+function. The only thing you have to implement is a clocksource driver and
+to register it at runtime.
+
+@code
+static uint64_t mycpu_clocksource_read(void)
+{
+	TODO
+}
+
+static struct clocksource cs = {
+	.read	= mycpu_clocksource_read,
+	.mask	= 0xffffffff,
+	.shift	= 10,
+};
+
+....
+	init_clock(&cs);
+....
+@endcode
+
+See arch/arm/mach-imx/clocksource.c for an example. clocksource drivers from
+the Linux Kernel can be used nearly 1:1, except for the register accesses.
+
+Note: For clocksources the __lshrdi3 symbol is needed. You can find the
+function for your architecture in the Linux Kernel or a libc of your choice.
+
+Note: U-Boot-v2 expects an upward counting counter!
