+Supported Boot Devices
+======================
+
+The OpenPower firmware uses Linux as a bootloader in order to discover boot
+devices, and boot the final operating system. In order to discover boot devices
+and load the operating system image from them, the bootloader's kernel needs to
+include support for that hardware.
+
+This table lists the network adaptors and disk controllers that are currently
+enabled.
+
+If you are adding a device to the kernel, please add the details here including
+your email address in the owner field. We will use this to contact users when
+considering the removal of modules.
+
+Likewise, if you are removing an option from the kernel config, please remove
+it from this table and notify the person mentioned in the owner field.
