/** @file
*
* Definitions for handling vector tables.
*
* This implements d0002_efm32_cortex-m3_reference_manual.pdf's figure 2.2
* (from the EFM32 documentation at
* http://www.energymicro.com/downloads/datasheets), and was seen analogously
* in other ARM implementations' libopencm3 files.
*
* The structure of the vector table is implemented independently of the system
* vector table starting at memory position 0x0, as it can be relocated to
* other memory locations too.
*
* The exact size of a vector interrupt table depends on the number of
* interrupts IRQ_COUNT, which is defined per family.
