 B4860 Overview
 -------------
 The B4860 QorIQ Qonverge device is a Freescale high-end, multicore SoC based on
-StarCore and Power Architecture® cores. It targets the broadband wireless 
+StarCore and Power Architecture® cores. It targets the broadband wireless
 infrastructure and builds upon the proven success of the existing multicore
 DSPs and Power CPUs. It is designed to bolster the rapidly changing and
 expanding wireless markets, such as 3GLTE (FDD and TDD), LTE-Advanced, and UMTS.
