fee92f1202 hook_call_deferred() works before tasks have started
State machines implemented using deferred functions need to be able to
kick off deferred function from a HOOK_INIT handler.  But tasks aren't
running in HOOK_INIT, so task_wake() fails.

Instead, hook_call_deferred() should check to see if the hook task has
had a chance to run yet.  If it hasn't, then there's no need to wake
it; it'll get run eventually anyway.

BUG=chrome-os-partner:24892
BRANCH=rambi
TEST=Add a call to hook_call_deferred() in a HOOK_INIT handler.  It shouldn't
     crash, and the deferred function should be called.

221ec5438a ite: WORKAROUND reduce data SRAM to 8kB
On the IT8380, we should be able to map 16kB of SRAM to use as data

56dd81e39c Merge make_all.sh to Makefile
By merging make_all.sh to Makefile, parallel make can be made faster.
Previously, if one does 'util/make_all.sh -j32', most of the time is
spent on waiting for linking. Now that we invoke sub-make, linking an
executable doesn't block the next board.

With '-j32', the new 'make buildall' takes about 7 seconds, while the
original 'util/make_all.sh' takes about 27 seconds.

700adf4dea Let AP read sensor IDs when DPTF thermal thresholds crossed
The spec does not mandate any way to read back the threshold settings
themselves, but when a threshold is crossed the AP needs a way to determine
which sensor(s) are responsible. Each reading of the EC_ACPI_MEM_TEMP_ID
register clears and returns one sensor ID that has crossed one of its
thresholds (in either direction) since the last read. A value of 0xFF means
"no new thresholds have tripped". Changing or enabling the thresholds for
any sensor will clear the unread event count for that sensor.

BUG=chrome-os-partner:23970
BRANCH=none
TEST=manual

On the host, set a couple of thresholds to low values so they trip
immediately (I'm testing on Link):

  # dptf() {
         [ "$#" -eq "2" ] || return;
         iotools io_write8 0x66 0x81
         iotools io_write8 0x62 $1
         iotools io_write8 0x62 $2
  }
  #

  # dptf 5 0
  # dptf 6 10
  # dptf 7 3

  # dptf 5 2
  # dptf 6 10
  # dptf 7 2

On the EC console, see that two thresholds have triggered, and that there
are two bits set in the AP seen mask:

  [45.755365 DPTF sensor 0, threshold -63 C, index 1, enabled]
  [45.768940 DPTF sensor 2, threshold -63 C, index 0, enabled]
  [46.169490 DPTF over threshold [0][1]
