Added --terse and --mailback options to the make stylecheck target. It also does continue even if it enounters a possible error. We decided on two exceptions from the linux kernel coding standard: - Empty wait while loops may end with ; on the same line. - All blocks after while, if, for have to be in brackets even if they only contain one statement. Otherwise it is easy to introduce an error. Checkpatch needs to be adapted to reflect those changes.

/** @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.
