+ * Remote BIOS Update (rbu) driver is used for updating DELL BIOS by

+ * application to set the CMOS bit indicating the BIOS to update itself
+ * after a reboot.
+ *
+ * Contiguous method:
+ * This driver writes the incoming data in a monolithic image by allocating
+ * contiguous physical pages large enough to accommodate the incoming BIOS
+ * image size.
+ *
+ * Packetized method:
+ * The driver writes the incoming packet image by allocating a new packet
+ * on every time the packet data is written. This driver requires an
+ * application to break the BIOS image in to fixed sized packet chunks.
