This is just an example, demonstrating how a userspace program can access
and control the Pixel lighbar. This change reflects the new unprivileged
access methods. You can run this program to drive the lightbar without being
root.
BUG=chromium:239205
BRANCH=none
TEST=manual
Nothing builds this by default, but you can test it with
cd src/platform/ec
gcc -static util/lbplay.c
then copy a.out to your Pixel and run it (from /tmp, since other directories
are mounted noexec).

Samsung change the temperature range in battery discharing state from (0

change the battery_temperature_range structure value as soon as possible
so that our reliability team check the battery.

This speeds up memcpy by copying a word at a time if source and destination are
aligned in mod 4. That is, if n and m are a positive integer:
4n -> 4m: aligned, 4x speed.
4n -> 4m+1: misaligned.
4n+1 -> 4m+1: aligned in mod 4, 4x speed.
Ran the unit test on Peppy:
> runtest
...
Running test_memcpy... (speed gain: 120300 -> 38103 us) OK
...
Ran make buildall -j:
...
Running test_memcpy... (speed gain: 2084 -> 549 us) OK
...
Note misaligned case is also optimized. Unit test runs in 298 us on Peppy while
it takes about 475 with the original memcpy.
TEST=Described above.

This is experimental for now; the capsense chip simply reports its buttons
as the number keys on the keyboard (1-8).
BUG=chrome-os-partner:23382
BRANCH=samus,ToT
TEST=manual
To test, you'll need a reworked and correctly programmed capsense module.
Boot the system, and switch to VT2. Touch the capsense bar and you'll see
the input appear on the console as though you were typing numbers.
Note that the capsense hardware is still buggy. Refer to the bug for
workarounds.

If a key is pressed which is not in actual_key_mask, this triggers the
keyboard scan interrupt. But read_matrix() would use the key mask to
decide that no *real* keys were pressed. So it would immediately drop
out of scan mode back to interrupt mode. Which would again be
triggered. Lather, rinse, repeat, watchdog.
The fix is to use the unmasked key matrix to decide whether to stay in
scan mode. This way, the keyboard task sleeps between scans, and the
watchdog isn't triggered.
(Note that the only way you can hit this bug in real life is to have a
keyboard attached which can trigger keys not in actual_key_mask.
Which is hard to do, unless you've got a new prototype keyboard with
extra keys, or you've spilled lemon juice on your Chromebook...)

BRANCH=rambi
TEST=Zero out actual_key_mask in keyboard_scan.c. Press a key. Should

We noticed this on a baytrail board, but the same problem exists in
haswell as well. And while looking there, found that we skipped the
S5G3 state if the 5V rail failed to come up.
Fortunately, these are all rare corner cases; rails will always come
up on a good system. So this only affects systems during bringup and
factory, not devices in the field.

between address write and data read/write. Using auto-increment mode, we

write.
