In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.

This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.

The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

- * Battery info for all Redrix battery types. Note that the fields

- * Fuel Gauge (FG) parameters which are used for determining if the battery
- * is connected, the appropriate ship mode (battery cutoff) command, and the
- * charge/discharge FETs status.
- *
- * Ship mode (battery cutoff) requires 2 writes to the appropriate smart battery
- * register. For some batteries, the charge/discharge FET bits are set when
- * charging/discharging is active, in other types, these bits set mean that
- * charging/discharging is disabled. Therefore, in addition to the mask for
- * these bits, a disconnect value must be specified. Note that for TI fuel
- * gauge, the charge/discharge FET status is found in Operation Status (0x54),
- * but a read of Manufacturer Access (0x00) will return the lower 16 bits of
- * Operation status which contains the FET status bits.
- *
- * The assumption for battery types supported is that the charge/discharge FET
- * status can be read with a sb_read() command and therefore, only the register
- * address, mask, and disconnect value need to be provided.
