Added: cpu/x86/pc/olpc/suspend.fth Modified: cpu/x86/pc/olpc/devices.fth cpu/x86/pc/olpc/fw.bth cpu/x86/pc/olpc/micin.fth dev/olpc/touchpad/touchpad.fth Log: OLPC trac #1371 - Get board revision from EC. I revamped the board revision sensing code, moving some distributed logic into one place. The word "board-revision" now returns a number that has 3 digits when represented in hex. The first 2 digits are the "conventional" board revision number, e.g. "B3", and the third digit indicates build stages. Pre-B3 is h# B30 , first production B3 will be B38, and subsequent variations might be B39, B3A, etc. In general, the pre- version will have third digit 0 and the first production version will have third digit 8. I did it this way so the numbers increase monotonically, to make it easy to test for "a certain revision or later".
This checkin also adds a suspend/resume test to the touchpad tracking test. If you type 's' while in the middle of the touchpad test, the system will suspend, and when you resume it with the power button, the touchpad test continues.
