qmod: lower VCC threshold to 2.5V

on the QMOD board the VCC signal from the modem is measured using
an ADC (SIMtrace board just use card detect).
the threshold to consider VCC as activated was set to 2.8V, which
gives a bit of margin for the expected 3.0V.
still, we had one board where the voltage was 2.8V.
to be resilient against lower than expected voltages from
modems (or boards), we lowered the threshold to 2.5V.
this is still save for the SAM3S to correctly identify high/low
levels.

 Accepted values: 0 (NO_TRACE) to 5 (DEBUG)
 
+The qmod specific option `ALLOW_PEER_ERASE` controls if the UART debug command to assert the peer SAM3S ERASE line is present in the code.
+Per default this is set to 0 to prevent accidentally erasing all firmware, including the DFU bootloader, which would then need to be flashed using SAM-BA or JTAG/SWD.
+Setting `ALLOW_PEER_ERASE` to 1 enables back the debug command and should be used only for debugging or development purposes.

-/** \addtogroup usart_module Working with USART
- * The USART driver provides the interface to configure and use the USART peripheral.\n
- *
- * The USART supports several kinds of comminication modes such as full-duplex asynchronous/
- * synchronous serial commnunication,RS485 with driver control signal,ISO7816,SPI and Test modes.
- *
- * To start a USART transfer with \ref AT91SAM3S_PDC "PDC" support, the user could follow these steps:
- * <ul>
- * <li> Configure USART with expected mode and baudrate(see \ref USART_Configure), which could be done by:
- * -# Resetting and disabling transmitter and receiver by setting US_CR(Control Register). </li>
- * -# Conifguring the USART in a specific mode by setting USART_MODE bits in US_MR(Mode Register) </li>
- * -# Setting baudrate which is different from mode to mode.
-   </li>
- * <li> Enable transmitter or receiver respectively by set US_CR_TXEN or US_CR_RXEN in US_CR.</li>
- * <li> Read from or write to the peripheral with  \ref USART_ReadBuffer or \ref USART_WriteBuffer.
-        These operations could be done by polling or interruption. </li>
- * <li> For polling, check the status bit US_CSR_ENDRX/US_CSR_RXBUFF (READ) or US_CSR_ENDTX/
-        US_CSR_TXBUFE (WRITE).  </li>
- * <li> For interruption,"enable" the status bit through US_IER and
-        realize the hanler with USARTx_IrqHandler according to IRQ vector
-        table which is defined in board_cstartup_<toolchain>.c
-        To enable the interruption of USART,it should be configured with priority and enabled first through
-        NVIC .</li>
- * </ul>
- *
- * For more accurate information, please look at the USART section of the
- * Datasheet.

+/** \addtogroup usart_module Working with USART
+ * The USART driver provides the interface to configure and use the USART peripheral.\n
+ *
+ * The USART supports several kinds of comminication modes such as full-duplex asynchronous/
+ * synchronous serial commnunication,RS485 with driver control signal,ISO7816,SPI and Test modes.
+ *
+ * To start a USART transfer with \ref AT91SAM3S_PDC "PDC" support, the user could follow these steps:
+ * <ul>
+ * <li> Configure USART with expected mode and baudrate(see \ref USART_Configure), which could be done by:
+ * -# Resetting and disabling transmitter and receiver by setting US_CR(Control Register). </li>
+ * -# Conifguring the USART in a specific mode by setting USART_MODE bits in US_MR(Mode Register) </li>
+ * -# Setting baudrate which is different from mode to mode.
+   </li>
+ * <li> Enable transmitter or receiver respectively by set US_CR_TXEN or US_CR_RXEN in US_CR.</li>
+ * <li> Read from or write to the peripheral with  \ref USART_ReadBuffer or \ref USART_WriteBuffer.
+        These operations could be done by polling or interruption. </li>
+ * <li> For polling, check the status bit US_CSR_ENDRX/US_CSR_RXBUFF (READ) or US_CSR_ENDTX/
+        US_CSR_TXBUFE (WRITE).  </li>
+ * <li> For interruption,"enable" the status bit through US_IER and
+        realize the hanler with USARTx_IrqHandler according to IRQ vector
+        table which is defined in board_cstartup_<toolchain>.c
+        To enable the interruption of USART,it should be configured with priority and enabled first through
+        NVIC .</li>
+ * </ul>
+ *
+ * For more accurate information, please look at the USART section of the
+ * Datasheet.
