Thanks to the tech comms folks at Arm, this should now be available and
work is ongoing to open up more of the documentation too.

For example, the A76 SDEN is here:

	https://static.docs.arm.com/sden885749/d/Arm_Cortex-A76_MP052_Software_Developer_Errata_Notice_v16.0.pdf

and if you hammer "cortex a76 1463225" into google, then it shows up
after the Linux hits.
