malta: add script & instructions to flash U-boot
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 doc/README.malta for usage instructions. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

+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.
