-	  This driver supports the gigabit Ethernet on the Marvell MV643XX
-	  chipset which is used in the Momenco Ocelot C and Jaguar ATX and
-	  Pegasos II, amongst other PPC and MIPS boards.
+	  This driver supports the gigabit ethernet MACs in the
+	  Marvell Discovery PPC/MIPS chipset family (MV643XX) and
+	  in the Marvell Orion ARM SoC family.
+
+	  Some boards that use the Discovery chipset are the Momenco
+	  Ocelot C and Jaguar ATX and Pegasos II.
