/**
|
|
* @file
|
|
* @brief Populated exception vector table
|
|
*
|
|
* Vector table with exceptions filled in. The reset vector is the system entry
|
|
* point, ie. the first instruction executed.
|
|
*
|
|
* The table is populated with all the system exception handlers. No exception
|
|
* should not be triggered until the kernel is ready to handle them.
|
|
*
|
|
* We are using a C file instead of an assembly file (like the ARM vector table)
|
|
* to work around an issue with the assembler where:
|
|
*
|
|
* .word <function>
|
|
*
|
|
* statements would end up with the two half-words of the functions' addresses
|
|
* swapped.
