    This is a very broad topic, it also depends highly on what type of optimization you are looking for. One place to start is look through the include/configs .h file for the target board you are looking to optimize. There are several build configuration parameters here, some related to optimization. The u-boot readme file has some info on what the various build switches that are available.

    Hi patton,

    I started to optimize the u-boot code,

    started from arch/arm/lib/board.c file, where i have commented unwanted functions,

    But still my u-boot.bin image size is around 206KB, So still need less , where else i can think of reducing the code,

    can you suggest?

    Santosh,

    Perhaps this lab will help you with some of your boot time optimization.
