Subject: [PATCH v3 0/4] memblock tests: add VERBOSE and MEMBLOCK_DEBUG Makefile options

These patches add options VERBOSE and MEMBLOCK_DEBUG to Memblock
simulator, which can be specified when running make. These patches also
implement the functionality for these options.

VERBOSE
Usage:

$ make VERBOSE=1

Passing VERBOSE=1 will enable verbose output from Memblock simulator. For
each test, the verbose output includes the name of the memblock function
being tested, the name of the test, and whether the test passed or failed.
Since all the tests in Memblock simulator run as one monolithic test, this
output is a quick way to get a summary of test results.

MEMBLOCK_DEBUG
Usage:

$ make MEMBLOCK_DEBUG=1

Passing MEMBLOCK_DEBUG=1 will enable memblock_dbg() messages. These
are debug messages built into several functions in memblock that include
information such as the name of the function and the size and start and
end addresses of the memblock region.

Rebecca Mckeever (4):
  memblock tests: add user-provided arguments to Makefile
  memblock tests: add verbose output to memblock tests
  memblock tests: set memblock_debug to enable memblock_dbg() messages
  memblock tests: remove completed TODO items
