memblock tests: Add memblock_alloc_try_nid tests for top down
Add tests for memblock_alloc_try_nid for top down allocation direction.
As the definition of this function is pretty close to the core
memblock_alloc_range_nid, the test cases implemented here cover most of
the code paths related to the memory allocations.
The tested scenarios are:
- Region can be allocated within the requested range (both with aligned
and misaligned boundaries)
- Region can be allocated between two already existing entries
- Not enough space between already reserved regions
- Memory range is too narrow but memory can be allocated before
the maximum address
- Edge cases:
+ Minimum address is below memblock_start_of_DRAM()
+ Maximum address is above memblock_end_of_DRAM()
Add checks for both allocation directions:
- Region starts at the min_addr and ends at max_addr
- Maximum address is too close to the beginning of the available
memory
- Memory at the range boundaries is reserved but there is enough space
to allocate a new region
