This patch adds a script which may be used with MIPS Navigator Console
and a MIPS Nagivator Probe in order to flash U-boot to a MIPS Malta
development board.

Please see the newly added board/malta/README for usage instructions.

+MIPS Malta board
+
+How to flash using a MIPS Navigator Probe:
+
+  - Ensure that your Malta has jumper JP1 fitted. Without this jumper you will
+    be unable to flash your Malta using a Navigator Probe.
+
+  - Connect Navigator Console to your probe and Malta as usual.
+
+  - Within Navigator Console run the following commands:
+
+      source /path/to/u-boot/board/malta/flash-malta-boot.tcl
+      reset
+      flash-boot /path/to/u-boot/u-boot.bin
+
+  - You should now be able to reboot your Malta to a U-boot shell.
