New Revision: 231161
URL: http://svn.freebsd.org/changeset/base/231161
Log:
- Give all clocks and timers on acpi0 the equal probing order.
- Increase probing order for ECDT table to match HID-based probing.
- Decrease probing order for HPET table to match HID-based probing.
- Decrease probing order for CPUs and system resources.
- Fix ACPI_DEV_BASE_ORDER to reflect the reality.
