there seems not to be anything family specific about the interrupt vectors of m3 based efm32 systems, thus renaming vector.h to irq.h

|
|
* Definitions for handling vector tables.
|
|
*
|
|
* This implements d0002_efm32_cortex-m3_reference_manual.pdf's figure 2.2.
|
|
*
|
|
* 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.
