-           Mips atlas board has jumper  which will redirect accesses from “Bootcode” range to either “Monitor flash” (0x1e000000) or the upper 4MB of “System flash” (0x1dc00000) based on jumper settings. if my kmc board have some jumper like this, can I redirect the start address.

Of course, what is really happening there is that the Atlas boot ROM has a vector at 0x1fc00000 which reads the jumper and jumps to one address or the other depending on the jumper setting. If you control what is in ROM at 0x1fc00000 and you have a software-readable jumper on your KMC board, you can do the same thing.
