+---------

+The XScale cores were designed by Intel, and shipped by Marvell in the older
+PXA processors. Feroceon is a Marvell designed core that developed in-house,
+and that evolved into Sheeva. The XScale and Feroceon cores were phased out
+over time and replaced with Sheeva cores in later products, which subsequently
+got replaced with licensed ARM Cortex-A cores.
