4 TF-A's memory layout tool is a Python script for analyzing the virtual
5 memory layout of TF-A builds.

39 main memory regions in an ELF file (i.e. text, bss, rodata) but can be modified
44     $ poetry run memory symbols
114     poetry run memory --help
119 The tool enables users to view static memory consumption. When the ``footprint``
121 generate a table (per memory type), showing memory allocation and usage. This is
126     $ poetry run memory footprint
153 A hierarchical view of the memory layout can be produced by passing the ``tree``
159     $ poetry run memory tree
212     $ poetry run memory tree --depth 2
