Yes, but It depends on the architecture and port.  For OMAP24xx board
you can use jtag and load directly into SDRAM and execute, or you can
change the base address in config.mk and compile for SRAM and load and
run from there.   It is handy to  use u-boot from RAM to burn a version
into flash.


For this to work, along with the compile addresses, the code needs to
worry about modifying clocks while executing in a given memory.  The
ARM-242X port does this at run time, others may or may not.

Can i use the u-boot.bin file directly too boot from RAM rather than
storing it to FLASH?

If i can What are the necessary changes i should make.in the free source
