STM32F0 Discovery -> ST Link V2

Going through the schematics for the board I see that the ST Link is connected to the JTAG programming connections to the F0 chip from the F1 chip.  So all the drivers etc. handle this connection normally.

But there are two connections that are through a solder bridge which is not connected from the factory:

STM32F0_USART1_RX

STM32F0_USART1_TX

I could not find any information regarding these.  I did read that there is a USART bootloader that can be used to program the F0 serially but nothing that indicates if I remove the jumpers for the JTAG programming connection and solder the serial bridges that this would work as a USB to SERIAL programmer.

Is there any further information on this anywhere?

This are just pins through which you can send commands via USART, yet you need to enter into bootloader state with pulling boot pin.
