Phone boot with PWON: weed out short button presses Every standard end user phone has a design provision, most naturally implemented in firmware, whereby the PWON button effects a boot only if it is held down long enough - short presses of this PWON button are detected, assumed to be spurious and cause the fw to power back off instead of proceeding with boot. The present change introduces this standard function in FreeCalypso.

FC Tourmaline stdmodem functional configuration is equivalent to Magnetite
hybrid.  The only intentional diff from Magnetite to Tourmaline in the modem
configuration is the change of Nucleus: Magnetite uses the blob version of
Nucleus which came with TCS211-20070608, whereas Tourmaline uses the source
version of Nucleus by Comrade XVilka.  It is essentially a change from an
unknown version of Nucleus to a known one, thus it should generally be
considered an improvement - but as always with such changes, extensive
verification and testing needs to be done in order to ensure that nothing got
broken.

Aside from the one intentional change of Nucleus version, FC Tourmaline is an
entirely new firmware source tree, thus it is always possible that something
could have got broken unintentionally, particularly in rarely-tested areas of
the firmware.  Therefore, extensive testing will need to be done before we can
declare Tourmaline stdmodem as officially replacing Magnetite hybrid for stable
modem products.
