I am trying to find a datasheet for one of the following cores: BCM11311 or bcm21654. Which have an ARMv7-A architecture and ARM cortex 9 processor. However I am completely unable to find any usefull datasheet of the BCM11311 or bcm21654 on the internet. I have seen there is code available to port freertos to a cortex A9 processor, so I am looking for any chip which has this architecture. So I can lookup all the register addresses and analyze all the code.
Why can't I find a datasheet of any of these?
