79 * The following conditional compilation control is a FreeCalypso addition.
80 * TI's original code always configured the BCICONF register with
81 * MESBB and BBCHGEN bits set, enabling both charging and the measurement
82 * resistive divider for the backup battery. However, on our primary
83 * hw targets (Openmoko GTA02 and our own FCDEV3B) Iota's VBACKUP pin
84 * is unconnected, whereas on Mot C139 and Pirelli DP-L10 "alien" hw
85 * the VBACKUP situation is unclear. But at least on our known hw
86 * with VBACKUP unconnected, it is better to leave backup battery charging
87 * and measurement OFF - TI's original config seems to be a drain on
88 * the main battery. Therefore, we are going to leave MESBB and BBCHGEN
89 * off until and unless we have a hw target where backup battery charging
90 * and measurement are appropriate.
