fix typo affecting initial state of EN_3_3V_SOC
disable power controls during stop mode (safe, since we know the board is off at this point), to reduce leakage
add git hash to version info
fix handling of uppercase hex digits in tohex(), and "make format"
disable more internal clocks, guided by new EnE docs
add CMD_RESET_EC and CMD_RESET_EC_SOFT protocol commands, for resetting the 8051 core, and the whole chip, respectively.
add 'r'eset command, and rearrange watchdog exercise commands.
use internal oscillator for watchdog, so it runs in stop mode, and add watchdog_reboot() routine.
fix bug in enable/disable_EN_SD[12] macros
turn off trim_tune() debug output, and enable stop mode.
turn off stop mode debug output
disable the spi host controller in powerdown state, to reduce leakage.
add commands for more watchdog control, for debug
reintroduce failsave recover loop at top of main.
configure the EDI CS input to wake us, so we can program the EC when in STOP mode.
make the AC input wakeup work, by switching to edge-triggered from toggle-triggered. toggle-triggered should have worked.
get rid of extra wakeup PF flag, by setting GPIO2D (TP167, used for the gpt3 timer output heartbeat) to output-only. also ifdef the stop-mode debug code. AC jack wakeups are still disabled.
Add delay prior to entering stop mode.
Make main_io3731 the default main.c via symlink
