New Revision: 259640
URL: http://svnweb.freebsd.org/changeset/base/259640
Log:
Add identification and necessary type checks for Krait CPU cores. Krait CPU
is used in
Qualcomm Snapdragon S4 and Snapdragon 400/600/800 SoCs and has architectural
similarities to ARM Cortex-A15. As for development boards IFC6400 series
embedded
boards from Inforce Computing uses Snapdragon S4 Pro/APQ8064.
