* @brief Adjust size, alignment and caps of a memory allocation request to the specific

|
|
* hardware requirements, dependent on where the memory gets allocated.

|
|
*
|
||
|

* @note Note that heap_caps_base.c has its own definition for this function in order not to depend
|
||
|
|

|
|
*
|
||
|
|
* @param[in,out] p_alignment Pointer to alignment requirements. This may be modified upwards if the
|
||
|
|
* hardware has stricter alignment requirements.
|
||
|
|
* @param[in,out] p_size Pointer to size of memory to be allocated. This may be modified upwards
|
||
|
|
* if e.g. the memory needs to be aligned to a cache line.
|
||
|
|
* @param[in,out] p_caps Pointer to memory requirements. This may be adjusted if the memory
|
||
|
|
* requirements need modification for the heap caps allocator to work
|
||
|
|
* properly.
