I have gone through the FAQ section, this FAQ only talks about the condition where the other Uboot is in RAM but what I am thinking is to boot the Uboot from the flash location by another running Uboot.
This doesn't make any difference. Read more carefully, and read to the end. Pay special attention to the part here:
U-Boot expects to see a virgin CPU, i. e. the CPU state must match what you see if the processor starts executing the first instructions when it comes out of reset. If you want to start U-Boot from another boot loader, you must disable a lot of code ...
