New Revision: 298854
URL: https://svnweb.freebsd.org/changeset/base/298854
Log:
Add a MULTIDELAY option to allow the ARM kernel to have multiple DELAY
implementations. Early in the boot the kernel will use an approximate,
however after the timer has been probed it will switch to a more accurate
implementation.
