/* linker script for application running on STM32F103x8 micro-controller

* the STM32F103xB has 128 KB of flash starting at 0x0800 0000, and 20 KB of RAM starting at 0x2000 0000
* STM32F103x8 most often have if fact 128 KB, instead of the specified and advertised 64 KB, like the STM32F103xB
* you can define the desired flash size here.

* the USB DFU bootloader will take the first 8 KB of flash, followed by the application
* the first 4 bytes of the RAM is reserved for the DFU magic word (DFU! to start DFU bootloader)
