| Shouldn't this be configurable? We already have a command for enabling
| 500mA charging so why not add a command to enable 100mA charging too?
|
| "neo1973 charger fast - enable fast (500mA) charging\n"

I can see the logic, but why in U-Boot?  Are people really sitting in
U-Boot and need more commands for stuff like charging?
