SFI: add sysfs interface for SFI tables.
Analogous to ACPI's /sys/firmware/acpi/tables/...
create /sys/firmware/sfi/tables/
The tables are primariy for the kernel,
but sometimes it is useful for user-space to be
able to read them.

1 | What: /sys/firmware/sfi/tables/ | ||
2 | Date: May 2010 | ||
3 | Contact: Len Brown <lenb@kernel.org> | ||
4 | Description: | ||
5 | SFI defines a number of small static memory tables | ||
6 | so the kernel can get platform information from firmware. | ||
7 | |||
8 | The tables are defined in the latest SFI specification: | ||
9 | http://simplefirmware.org/documentation | ||
10 | |||
11 | While the tables are used by the kernel, user-space | ||
12 | can observe them this way: | ||
13 | |||
14 | # cd /sys/firmware/sfi/tables | ||
15 | # cat $TABLENAME > $TABLENAME.bin | ||
