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.

// The absolutely easiest way to disable FFS altogether is to set
// ffs_flash_manufact = 0x99 and ffs_flash_device = 0x9999. Because this is
// (as of today at least) an undefined device, FFS will NOT initialize and
// every FFS function call will fail (with no side-effects).

// FFS will automatically detect the flash device if both ffs_flash_manufact
// and ffs_flash_device are zero. Note that this works *only* if the flash
// device is mapped at address zero. Otherwise you *have* to supply
// manufacturer and device IDs.

// FFS can be configured to run in ram only. In this case the
// 'ffs_flash_manufact' must be set to MANUFACT_RAM and an address to a
// static user allocated ram buffer must be applied to the variable
// 'ffs_flash_address'. In a ram configuration the 'ffs_flash_device' is an
// arbitrary value that must be in sync with the 'device code' value chosen
