load image into cache and execute it in cache

Note: This was originally posted on 31st January 2013 at http://forums.arm.com

Hi Experts:

    i have heard that some ARM platform providers load their bootloader into L2 cache, and execute the bootloader in L2 cache directly.

    how can this work? do they add some logic inside silicon to make this work?

    as my understanding, cache has differnt architecture from normal sram, how can CPU recognize the L2 cache as a normal sram and execute image in it directly?

Best Regards
