Remote update controller issue

Here is the file I modified in the boot loader program. I also included the original Altera code from Quartus 8.1. You must change the boot address to your application.

Note that there is a test on the Device ID in the code, so this code will for example not work for Stratix IV without modification. It may however work with cyclone IV. This test on Device ID has been removed in later versions of the boot code from Altera, and you can include my modifications in the new version. I also think you must modify the code if the lower 16 bits in the boot address is not 0.
