Hello TI expert
I am optimizing the bootup timing for AM6254 board with ramdiskfs.
So, I saw the [ 10.216730] random: crng init done takes around 9 second
My config:
CONFIG_HW_RANDOM=y
CONFIG_HW_RANDOM_TIMERIOMEM=y
CONFIG_HW_RANDOM_OPTEE=y
How can I reduce this time to less than 1 second.
thanks,
Brian
