 TODO
 =====
 
-1. Add verbose output (e.g., what is being tested and how many tests cases are
-   passing)
-
-2. Add flags to Makefile:
-   + verbosity level
-   + enable memblock_dbg() messages (i.e. pass "-D CONFIG_DEBUG_MEMORY_INIT"
-     flag)
-
-3. Add tests trying to memblock_add() or memblock_reserve() 129th region.
+1. Add tests trying to memblock_add() or memblock_reserve() 129th region.
    This will trigger memblock_double_array(), make sure it succeeds.
    *Important:* These tests require valid memory ranges, use dummy physical
                 memory block from common.c to implement them. It is also very
                 likely that the current MEM_SIZE won't be enough for these
                 test cases. Use realloc to adjust the size accordingly.
 
-4. Add test cases using this functions (implement them for both directions):
+2. Add test cases using this functions (implement them for both directions):
    + memblock_alloc_raw()
    + memblock_alloc_exact_nid_raw()
    + memblock_alloc_try_nid_raw()
 
-5. Add tests for memblock_alloc_node() to check if the correct NUMA node is set
+3. Add tests for memblock_alloc_node() to check if the correct NUMA node is set
    for the new region
