heap: ported tlsf allocator into multi heap heap_host_tests: added tlsf allocator into host test heap_host_test: update freebytes after using free heap_tests: tlsf now passing on host tests without poisoning multi_heap: added support for memalign using tlsf implementation heap_caps: removed heap_caps_aligned_free heap/test: fixed broken aligned alloc test build heap: added poisoning pattern when blocks are being merged heap/tests: added timing tests for memory allocation heap: reduced tlsf structure overhead heap/tlsf: made all short functions inside of tlsf module as inline to improve timings heap: moved tlsf heap routines outside of flash memory newlib: linked multiheap memalign with newlib memalign function heap: moved block member functions to a separate file so multi_heap can use the functions heap/test: improved the tlsf timing test heap/test: added memalign on aligned alloc tests heap: moved tlsf configuration constants to a separated file heap: added random allocations test with timings heap: modified the calculation of heap free bytes heap: make aligned free true deprecated functions and update their documentation heap: add extra assert after successive mallocs on small allocation host test heap: remove legacy aligned alloc implementation. performance: added malloc and free time performance default values
