+Subject: [PATCH] arm: kirkwood: add CheckPoint L-50 device
+
+This patch adds support for the Check Point L-50 from 600/1100 series
+routers.
+
+Specification:
+-CPU: Marvell Kirkwood 88F6821 1200MHz
+-RAM: 512MB
+-Flash: NAND 512MB
+-WiFi: mPCIe card based on Atheros AR9287 b/g/n
+-WAN: 1 Gigabit Port (Marvell 88E1116R PHY)
+-LAN: 9 Gigabit Ports (2x Marvell 88E6171(5+4))
+-USB: 2x USB2.0
+-Express card slot
+-SD card slot
+-Serial console: RJ-45 115200 8n1
+-Unsupported DSL
+
+Known limitations:
+- In board is used two switches in chain. Second Marvell is not used
+  in u-Boot.
