RTEMS integration layer

• RTEMS BSP implementation based on ECSS qualified BSP
• RTEMS BSP is a minimal set of drivers needed for booting RTEMS on the target platform
• It includes wrappers for the SYSTICK, RTC and UART drivers for the pre-qualified BSP
• All drivers from the ECSS qualified BSP can be integrated into RTEMS – the code is portable and the IRQ layer of the drivers is an abstraction that can be integrated by users with both bare-metal and RTOS-based applications
