You'll need to supply more information.  You haven't
even said what the LED is connected to, or what it is
that you're trying to learn.

Which means your question is probably of topic for u-boot list. Check a 
general embedded programming list.

To get you started, you will have to do some of the cpu/board 
initialization done u-boot in your code before you can flip that LED 
which could be as short as a few instructions that modify a specific 
memory location or significantly more complex routines depending on how 
the LED is interfaced.

Your CPU manual and board schematics and datasheet/user guide of the 
parts on the board and crafty use of google are your friend. You need to 
know some assembly programming for your CPU and be comfortable debugging 
via BDI debugger.
