+ARM Marvell SoCs
+================
+
+This document lists all the ARM Marvell SoCs that are currently
+supported in mainline by the Linux kernel. As the Marvell families of
+SoCs are large and complex, it is hard to understand where the support
+for a particular SoC is available in the Linux kernel. This document
+tries to help in understanding where those SoCs are supported, and to
+match them with their corresponding public datasheet, when available.
