a0cb64374a Process emulator UART events in interrupt context
Currently emulator UART input/output are processed in various context,
including UART thread, individual tasks, and tests. By moving the
processing to interrupt context, the way it works resemble real chips
more. Also, this provides a cleaner cut between emulated UART device and
UART processing code.

cdcaf6ed8a Add interrupt support for emulator
This provides us a way to inject interrupts during a test. If a test has
interrupt_generator() defined, it will run in a separate thread. The
generator can then trigger interrupts when it decides to. The current
running task is suspended while emulator is executing ISR.

Also fixes a bug that tasks run without scheduler notifying them during
emulator start-up.

3f00af41c4 nyan: don't touch GPIO setting while init alternate functions.
Old code reset some GPIO configurations with af->flags = 0 while
gpio_config_module(). This is bad because it could lead unexpected
behavior on the bus.

New code accepts GPIO_DEFAULT flag so that it doesn't touch the
GPIO setting while configuring alternate functions. This should not
effect other boards unless the GPIO_DEFAULT is set on that board.

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]

400d7758bd rambi: Add duplicate GPIO outputs for proto 2.0 board
Proto 2.0 makes these changes:
  KBD_IRQ# moves from PM4 to PM3.
  EC_PWROK moves from PH2 to PJ1.

Since PM3 and PJ1 are unused on proto 1.5, it's harmless to duplicate
the current functionality on those outputs.  We can remove the old
outputs when we deprecate the 1.5 boards.

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

 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]

Now watch the EC console while running on the host:

  dptf 6 80
  dptf 7 2
  dptf 7 3

The EC should say

878f29330b nyan: pull up AP_RESET_L for old boards
On older boards (< Rev2.2), AP_RESET_L was connecting to PMIC reset pin.
However, after 2.2 we use the PMIC_THERM pin instead. Thus, change this
pin to pull high for old boards. T\Otherwise cannot boot up.

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.

6f348ecf08 Remove unneeded TODO comment
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"
command. From the host side, test this interface from a root shell.

Read fan duty:

  iotools io_write8 0x66 0x80
  iotools io_write8 0x62 4
  iotools io_read8 0x62

Set fan duty to 100%:

  iotools io_write8 0x66 0x81
  iotools io_write8 0x62 4
  iotools io_write8 0x62 100

Set fan duty to 50%:

  iotools io_write8 0x66 0x81
  iotools io_write8 0x62 4
  iotools io_write8 0x62 50

Set fan duty to 0%:

  iotools io_write8 0x66 0x81
  iotools io_write8 0x62 4
  iotools io_write8 0x62 0

Set fan control back to automatic:

  iotools io_write8 0x66 0x81
  iotools io_write8 0x62 4
  iotools io_write8 0x62 -1
