-What:		/sys/firmware/sfi/tables/
-Date:		May 2010
-Contact:	Len Brown <lenb@kernel.org>
-Description:
-		SFI defines a number of small static memory tables
-		so the kernel can get platform information from firmware.
-
-		The tables are defined in the latest SFI specification:
-		http://simplefirmware.org/documentation
-
-		While the tables are used by the kernel, user-space
-		can observe them this way::
-
-		  # cd /sys/firmware/sfi/tables
-		  # cat $TABLENAME > $TABLENAME.bin

- * Unlike HPET, there is no master counter, therefore one of the timers are

- *  - timer 0 - NR_CPUs for per cpu timer
- *  - one timer for clocksource
- *  - one timer for watchdog driver.
- * It is also worth notice that APB timer does not support true one-shot mode,
- * free-running mode will be used here to emulate one-shot mode.
- * APB timer can also be used as broadcast timer along with per cpu local APIC
