+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.
