2.Modified warm_reset checking in gpio.c
3.Modified system_get_chip_name in system.c for package info.
4.Modified fan.c and pwm.c for:

● Fan stall condition event:
If the measured fan speed is lower than the lowLimit value (unless the Fan Speed Low Limit value is 0) or in case of erroneous measurement, the userCallback is called.
5. Change cycle_pluses to 480 in board.c
Issues fixed:
1. Jump data at top of RAM is getting corrupted. Changed the flag to
RESET_FLAG_RESET_PIN. Added a workaround method to fix VCC1_RST
issue.
2. Hibernate wake need to report whether wake reason was GPIO or RTC
3. Hibernate wake must be distinguishable from watchdog reset. The
booter will log reset reason in Code RAM. I copy the log data to
battery-backup RAM in little FW. And system driver will refer this
data to distinguish if it's watchdog reset or not.
4. Watchdog reset flag is not set. Same fix as 3.
5. Should return error if unable to clear SPI flash status register.
6. Remove chip_temp_sensor.c
7. Remove use of pstate from flash driver
8. Remove support for watchdog warm reset
9. Keyboard raw driver must support COL2 inverted
10. LPC memory mapped data must be read-only from host
11. LPC should support PLTRST# signal
12. Problems reading chip type/version. Use core registers and ROM data to read IDs.
13. When chip type/version is unknown, report hex value.
14. Watchdog does not consistently print panic information.
15. Remove console force enable logic.
16. Enable only the peripheral clocks that are needed. Please notice
user should add bit mask in CGC_XXX_MASK if they want to enable
additional module. For example, if user wants to enable PWM3, he must
add PWDWN_CTL2_PWM3_PD bit in CGC_PWM_MASK.
Please see HOOK_FREQ_CHANGE and HOOK_INIT these two hook functions.
If I turn off all I2C modules in system_pre_init and turn on the
modules I need in i2c_init, I found its freq is not correct. The root
cause is hook_notify(HOOK_FREQ_CHANGE) is executed first (in
clock_init) before i2c_init. At this time, i2c modules are power-down
and writing to freq register is useless. I re-execute freq-changed
hook function after turning on modules again.
17. MPU properly configured to prevent code execution from data RAM
18. Partial nvcontext implementation. Copy these 16 bytes in our battery-backup RAM.
Additional items we also modified:
1. pwm.c: Support open-drain IO type of PWM. (PWM IO-Type cannot by
determined by GPIO, we use bit 1 & 2 of function byte of gpio_alt_func
array to support it)
2. ec_npcxflash.c: Use definition to replace constant value. Stop

This separates the configuration of the ARM core GPIOs from the
routing of internal peripherals to external pins. Both are still
described in the gpio.inc file, but are less dependent on each
other.
BUG=chrome-os-partner:33818
BRANCH=none
TEST=manual
Before this CL, running "sysjump rw" or trying to use more than 8
GPIOs caused hangs and reboots. Now it doesn't.

Use the EC to check if PD MCU has crashed. The EC knows this
by checking the PD status bits: if PD MCU was in RW, and is
now in RO, AND it did not get to RO via a sysjump, then it
must have crashed. When the EC detects this, the EC will also
panic and reboot the entire system, so that we can software
sync to a known good state.
Also, when EC panics due to PD crash, it will log panic info.
BUG=chrome-os-partner:36636
BRANCH=samus
TEST=load onto samus EC and PD, try sysjump'ing back and forth
on PD MCU console and verify EC does not do anything. Crash
the PD MCU when in RW by reboot command and crash divzero command,
and make sure the EC panics with PD crash panic message. Crash
the PD MCU when in RO (before sysjumping to RW) and make sure
EC does not panic.

Add charge ramp module to samus. For BC1.2 DCPs allow ramping
up to 2A, and for BC1.2 SDPs allow ramping to 1A.
Charge ramp is disabled when in RO and write protected.
BUG=chrome-os-partner:34946
BRANCH=samus
TEST=tested with a variety of BC1.2 chargers, type-C only chargers,
and PD chargers to make sure we always stabilize charging at an
appropriate current limit.
tested in RO and write protected, BC1.2 chargers do not ramp. when
you jump to RW it does ramp.
