ARCv2 32 bit and ARCv3 64 bit share the same vector table structure but with different vector entry size (32 and 64 bit), so we can easily make vector table bit agnostic. Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Evgeniy Paltsev <PaltsevEvgeniy@gmail.com>

/**
|
|
* @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.
