Disable all H/W prefetchers on ARM Cortex A-57

Hi Community,

I am trying to disable the hardware prefetchers on arm cortex A57. This includes and cache line preftching or any other data pefetching etc.

I am aware of ARM's exception levels and the fact that i might have to tweak bootloader itself. 

Some set of blogs, specific registers to set/unset etc. or some flowchart regarding this specific/ similar problem would be a great assistance.

if anyone could help regarding this , then it would solve a long standing problem for me.
