Author: gonzo Date: Mon Apr 2 23:30:21 2018 New Revision: 331894 URL: https://svnweb.freebsd.org/changeset/base/331894
Log: MFC r306436-r306437, r306489, r306491 r306436 by manu: RPI-B: Add support for MULTIDELAY 100 cycles per us seems accurate enough, at least it's better than the 200 value that was used before. Reviewed by: andrew, imp Differential Revision: https://reviews.freebsd.org/D8062 r306437 by manu: RPI2: Add support for PLATFORM_SMP so we can later add it to GENERIC. Reviewed by: andrew Differential Revision: https://reviews.freebsd.org/D8063 r306489 by manu: bcm2835_cpufreq: Only attach driver if we correcly match on the machine compatible string. r306491 by manu: RPI2: Add support for MULTIDELAY, this is needed for inclusion into GENERIC.
