GRAN_ALIGNED should check that the memory block's alignment (log2align)
is correct, not that the memory block is aligned with the granule size.
This fixes DEBUGASSERT() in mm_granfree:
_assert: Assertion failed : at file: mm_gran/mm_granfree.c:49
The assertion triggers if granule size != alignment.
This patch refactors granule allocator to remove the 32 granules
limitation with the help of a gran_range_s structure and related
functions, see "mm_grantable.h" for details.
Below are the major functions explaining how this works:
- The gran_match() checks if a gran range all in the given state.
it gives last mismatch position when fails free range matching.
- The gran_search() tries to find the position of a free range.
It leverages last mismatch position from gran_match() to speed
up the search.
range size handling is mainly in gran_match() and gran_set_().
