c4383ca93f Fix watchdog in keyboard scan if key outside mask pressed
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...)

72481572aa Convert vboot hash calculation from task to deferred function
Vboot hash calculation takes ~350 ms during EC boot.  Since the hash
task is higher priority than the hook task, this starves all the hooks
during boot.

We could, in theory, fix that simply by swapping the priority of the
hook and hash tasks.  But then watchdog detection (in the hook task)
wouldn't detect hangs in the hash task.

A better fix (implemented here) is to convert the hashing operation to
a series of deferred function calls.  This gets rid of the hash task
entirely, and allows all pending hooks and other deferred function
calls to take place between each chunk of hashing.

On STM32-based boards, we need to bump up the hook task stack size,
since hashing is called from several layers deep in the hook task
instead of at the top of its own task, but this is still a net win of
several hundred bytes of SRAM.

BUG=chrome-os-partner:24892
BRANCH=rambi
TEST=Boot EC; look for "hash start" and "hash done" debug output.
     'taskinfo' shows at least 32 bytes of unused stack for HOOKS task.
     'hash ro' runs properly from EC console.

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.

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]

cddf8a545c Implement DPTF thermal thresholds
Any of the EC's temp sensors can have up to two independent thresholds
attached to them. When the temperature crosses the threshold (rising or
falling), a EC_HOST_EVENT_THERMAL_THRESHOLD event is sent to the AP. It's up
to the AP to read the sensor values and figure out why the event was sent.

The thresholds are set and enabled with ACPI writes to three registers in
the EC interface space: EC_ACPI_MEM_TEMP_ID, EC_ACPI_MEM_TEMP_THRESHOLD, and
EC_ACPI_MEM_TEMP_COMMIT. Refer to the comments in ec_commands.h for details
on their use.

ACPI does not provide any means to read the threshold settings (the AP will
just have to remember), but there is an EC console command "dptftemp", that
can be used to examine the current settings.

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

On the EC console, check the current threshold settings and temperatures:

> dptftemp
sensor   thresh0   thresh1
  0       ---        ---     PECI
  1       ---        ---     ECInternal
  2       ---        ---     I2C-Charger-Die
  3       ---        ---     I2C-Charger-Object
  4       ---        ---     I2C-CPU-Die
  5       ---        ---     I2C-CPU-Object
  6       ---        ---     I2C-Left C-Die
  7       ---        ---     I2C-Left C-Object
  8       ---        ---     I2C-Right C-Die
  9       ---        ---     I2C-Right C-Object

 12       ---        ---     I2C-Left D-Die
 13       ---        ---     I2C-Left D-Object
>
> temps
  PECI                : 318 K = 45 C
  ECInternal          : 306 K = 33 C
  I2C-Charger-Die     : 309 K = 36 C
  I2C-Charger-Object  : Not calibrated
  I2C-CPU-Die         : 309 K = 36 C
  I2C-CPU-Object      : Not calibrated
  I2C-Left C-Die      : 306 K = 33 C
  I2C-Left C-Object   : Not calibrated
  I2C-Right C-Die     : 307 K = 34 C
  I2C-Right C-Object  : Not calibrated
  I2C-Right D-Die     : 307 K = 34 C
  I2C-Right D-Object  : Not calibrated
  I2C-Left D-Die      : 306 K = 33 C
  I2C-Left D-Object   : Not calibrated
>

In this case, the PECI temp is 318 K, so let's set a threshold at 322 K. On
the AP:

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

Back on the EC console, we see that the threshold has been set:

  [768.176648 DPTF sensor 0, threshold 49 C, index 1, enabled]
  > dptftemp
  sensor   thresh0   thresh1
    0       ---        322     PECI
    1       ---        ---     ECInternal
    2       ---        ---     I2C-Charger-Die
  ...

Now do something on the AP to increase the temperature (webgl aquarium,
etc). When the temp goes above 322 K, the EC console reports it and sends a
host event, and the "dptftemp" command indicates the over-temp condition:

  [815.367442 DPTF over threshold [0][1]
  [815.367878 event set 0x00000100]
  [815.368069 sci 0x00000100]
  [815.368619 event clear 0x00000100]
  > dptftemp
  sensor   thresh0   thresh1
    0       ---        322*    PECI
    1       ---        ---     ECInternal
    2       ---        ---     I2C-Charger-Die
  ...

Log out and wait for the temp to drop. You'll see that trigger a host event
as well:

  [854.375713 DPTF under threshold [0][1]
  [854.376147 event set 0x00000100]
  [[854.376396 event clear 0x00000100]
  > dptftemp
  sensor   thresh0   thresh1
    0       ---        322     PECI
    1       ---        ---     ECInternal
    2       ---        ---     I2C-Charger-Die
  ...

d3fdf5e6f3 Add stubs for DPTF thermal thresholds

The registers are

  EC_ACPI_MEM_TEMP_ID            0x05
  EC_ACPI_MEM_TEMP_THRESHOLD     0x06
  EC_ACPI_MEM_TEMP_COMMIT        0x07

It doesn't actually do anything yet, but the AP can now write those values.

         iotools io_write8 0x62 $1
         iotools io_write8 0x62 $2
  }

Now watch the EC console while running on the host:

  dptf 5 1
  dptf 6 80
  dptf 7 2
  dptf 7 3

The EC should say

 DPTF sensor 1, threshold 7 C, index 0, enabled
 DPTF sensor 1, threshold 7 C, index 1, enabled

96e034f366 nds32: WORKAROUND for toolchain bug on rodata
Sometimes the toolchain tries to put a relocation which is not suitable
to access variables in a read-only section.

The nds32 gcc uses GP-relative signed 17-bit relocation to access
variables stored in .rodata (eg lwi.gp $r0, [ +gp ])
That's wrong since $gp is pointing in the middle of .data and .bss in
the SRAM, while .rodata is sitting in flash.
Since on IT8380, the flash is at 0x00000 and the SRAM is at 0x80000
(512kB further), the linker will fail trying to create the signed 17-bit
relocation (it detect that it needs to truncate it)

Force the compiler to put another relocation as a workaround for now.

When we are detecting Apple charger type, we disable TSU6721 interrupt.
This, however, doesn't create a race condition, because any pending
interrupt fires immediately after we re-enable TSU6721 interrupt, and in
turns schedules charger task. As a result, charger task gets waken right
after it finishes its current iteration.

As for overcurrent detection, the current algorithm seems to do a good
enough job.

1d24f4d661 keyboard: Improve kbpress reliability for automation
The "kbpress" command had a few issues if you wanted to reliably use
it for automation.  Specifically it was not possible to guarantee how
much time would pass between the press of a key and the release of a
key.  Sometimes you might press and release before the key was
officially "there" and sometimes you might get a press and hold of a
key.

Fix this:
1. Make it so that kbpress with no press/release parameter gives a
   press and release (and guarantees that the press / release will
   actually take effect).
2. Make it so that kbpress guarantees that when it finishes that the
   key has actually been pressed or released.

9f40f11fe8 Fix bug in Samus DPTF fan control
It worked on Link because the fan number and the fan channel were both 0.
Samus has two fans, connected to different GPIOs.

In the EC's ACPI interface block, register 0x04 is used to get and set the
fan's target duty cycle, as a percentage value. Writing a 0 to this register
will set the target duty cycle to 0, writing a 100 (0x64) will set it to
100%. Writing any other value will return the fan control to the EC, rather
than driving it manually from the host.

Likewise, reading from this register returns the current fan target duty
cycle, as a percentage. If the EC is controlling the fan automatically, the
returned value will be 0xFF.

BUG=chrome-os-partner:23972
BRANCH=samus
TEST=manual

You can monitor the fan state from the EC console with the "faninfo"

ebb54a453d nyan: add support of different battery types
Nyan EC supports 2 different boards: Venice2 and Norrin. Venice2
uses 2S battery, and Norrin uses 3S battery. This CL is to support
2 different battery types (2S or 3S) automatically at init time by
reading battery's MANUF_NAME, DEVICE_NAME and DESIGN_VOLTAGE from
Smart Battery Interface to determine which battery type to use.

To workaround the problem that battery may not be attached at init
time, a patch is added to call battery_get_info() in PWR_STATE_INIT
state to get the current battery info. Note the battery info is only
determined once.

BUG=none
BRANCH=nyan

c0ec787ba1 Add battery_get_params()
The charge state machine asks for all of this stuff at the same time
anyway.  Bundling it into a single function removes a number of
redundant (and painfully slow) I2C reads.

Also refactor the battery debug command so it doesn't have so many
local variables all in one function; it was consuming considerably
more stack space than any other debug command.

Spring still needs low-level access to the smart battery, so move the
two functions it needs directly into the Spring implementation.

f7dba327a2 Add DPTF interface for fan duty
This adds include/dptf.h to define the DPTF interface functions.

As the first DPTF feature, it also adds a register to the EC's ACPI
interface block. Register 0x04 is used to get and set the fan's target duty
cycle, as a percentage value. Writing a 0 to this register will set the
target duty cycle to 0, writing a 100 (0x64) will set it to 100%. Writing
any other value will return the fan control to the EC, rather than driving
it manually from the host.

Likewise, reading from this register returns the current fan target duty
cycle, as a percentage. If the EC is controlling the fan automatically, the
returned value will be 0xFF.

BUG=chrome-os-partner:23972
BRANCH=none
TEST=manual

You can monitor the fan state from the EC console with the "faninfo"
command. From the host side, test this interface from a root shell.
