- RATIONALE FOR THIS FUNCTION :
-
- - The STM32 embeds in ROM a bootloader that allows to
-   obtain code and boot from a number of different interfaces,
-   including USB in a mode called "DFU" (Device Frimware Update)
-   [see AN3606 from ST for full details]
-   This bootloader code is executed instead of the regular
-   application code when pin BOOT0 is pulled-up (which on
-   LimiFrog0.2 is achieved by pressing the general-purpose
-   pushbutton switch on the side.
- - The bootloader monitors a number of IOs of the STM32 to decide
-   from which interface it should boot.
- - Problem in LimiFrog (up to versions 0.2a at least): upon
-   power-up the BLE modules generates some activity on UART3,
-   which is part of the pins monitored by the STM32.
-   This misleads the bootloader in trying to boot from UART3
-   and, as a result, not continuing with booting from USB.
-
-  - This code implements an alternative solution to launch the
-  bootloader while making sure UART3 remains stable.
-  - The idea it to start application code with a check, prior to any
-  other applicative code, of whether USB bootload is required (as
-  flagged by a GPIO pulled low at reset, in the same way as BOOT0).
-  The hadware reset pin of BLE is asserted (so that now it won't
-  generate any acitivity on UART3), and if USB bootload is required :
-  bootload ROM is remapped at address 0x0, stack pointer is
-  updated and the code is branched to the start of the bootloader.
-  - This code is run prior to any applicative configuration of clocks,
-  IRQs etc. -- the STM32 is therefore still running from MSI
-
-  THIS FUNCTION MAY BE SUPPRESSED IF YOU NEVER NEED TO BOOT DFU MODE
