EC 4.0 Firmware

Ver: 7 0.4.02

• 0.4.02
• fix EC/SoC communication problems (#12525).

Ver: 7 0.4.01

• 0.4.01
• further lengthen EC_IRQ# timings for 1Ghz machines

Ver: 7 0.4.00

• 0.4.00
• Fix trac <trac>12558</trac>. Power LED while system is off
• disable the "rescue" EC_IRQ# assertion

Ver: 7 0.3.13

• 0.3.13
• revert wakeup timings to 3.0.11 values

Ver: 7 0.3.12

• 0.3.12
• ec_irq: add fallback to bail us out of incomplete suspends
• ec_irq: implement timing tuning commands in monitor

Ver: 7 0.3.11

• 0.3.11
• Allow battery debugging to be enabled via serial port
• Fix incorrect battery critical LED state
• Change W to mW in battery debug output to make the scale clearer
• Add debounce for the thermal alarm signal and enable a new LED state when triggered. (Alternating power LED and red battery LED)
• Blink code for high battery current prior to stop mode (Alternating Green/Yellow)
• Blink code for exiting stop mode while power is off (Alternating Green/Red)

Ver: 7 0.3.10

• 0.3.10
• Fix NiMH pre-maturely marked full problem

Ver: 7 0.3.09

• 0.3.09
• Fix logic bug in ext power detect after runin discharge. Machines turning off runin discharge could fail to sense external power.
• Print ACR value and SOC when going into stop mode
• Refactor critical and low flag handling to fix corner cases. There were several corner cases where you could get the previous code to display the wrong LED state.
• Add support for GP LiFePO4 batteries. There are few around the Twine offices.
• Turn off battery state debugs in LiFePO4 code
• kbdwatch: wait longer after seeing SOC_SLEEP to release flow-control. Fixes a lockup on 1Ghz MMP3.

Ver: 7 0.3.08

• Make sure full flag is clear when SOC is < 95%
• Up bad ACR read difference threshold to 20 counts
• Come out of stop mode once in a while, to do housekeeping
• adjust the timings for the EC_IRQ assertions

Ver: 7 0.3.07

• Check battery EEPROM bank 0 values and fix them if wrong
• Detect bad ACR register reads from the battery due to ESD and discard them
• Generate 2 wake up interrupts to the SoC on resume. One to make it wake up and then a 2nd to actually make it start executing. Works around resume problems.

Ver: 7 0.3.06

• Change battery over temperature indicator to be a pulse of dark (both LEDs off) rather than a pulse of red. Red is now exclusively for errors.
• Fix typo in IO map causing LV_SET code to mess with EC_IRQ.
