When PIE is enabled, it can be handy to display the .rela.dyn section.
Add RELA in the list of symbols parsed, to display this section in
memory map.

When building BL1 with SEPARATE_CODE_AND_RODATA=0, symbol names
__RO_{START|END}__ are ignored by memory map dump script.
Fix it by including the symbol in regular expression.
While at it, update the copyright year to current.

Calculate the free space as the range between the
limit and the end of the memory region *_REGION_END.

Add symbols to mark end of TEXT/RODATA before page alignment.
Similar change was done by commit 8d69a03f6a ("Various
improvements/cleanups on the linker scripts") for
RO_END/COHERENT_RAM. These symbols help to know how much free
space is in the final binary because of page alignment.
Also show all *UNALIGNED__ symbols via poetry.
For example:
poetry run memory -p zynqmp -b debug

The intial patch stack only supported ELF files, which proved
particularly problematic when dealing with incomplete builds (i.e. build
didn't complete due to linker errors). This adds support for GNU map
files. Most analysis performed by the tool should be possible with map
files alone.

Present memory usage in hierarchical view. This view maps modules to
their respective segments and sections.

Add support for tabulating static memory consumption data from ELF
binaries. This relies on static symbols, defined in the linker files,
that provide information about the memory ranges.

Make the symbol table produced by the memory mapping script more
readable. Add a generic interface for interacting with ELF binaries.
This interface enables us to get symbols that provide some insights into
TF-A's memory usage.

Add some entries in blx_symbols, that are used when the flag
SEPARATE_CODE_AND_RODATA is not enabled (__RO_* and __TEXT_RESIDENT_*).
Add all new symbols that were not yet present in the script.
Correct __BSS_END to __BSS_END__, and add __BSS_START__.
Add new *_XLAT_TABLE_* symbols.
As those strings are longer than 22, update display format string to
be dependent on the longest string.
The script also skips lines for which the _START__ and _END__
symbols have the same address (empty sections).

This patch:
- Add the __COHERENT_RAM_START__ and __COHERENT_RAM_END__ symbols.
- Improve how the symbols are found with a regex.
- Add a build option to revert the memory layout output.

show_memory is a simple tools that parse the blx.map files and print a
representation of the memory layout for the latest build.
This representation is based on standard symbols present on the map
files as: __TEXT_START/END__, __RODATA_START/END__, __STACKS_START/END__
, etc..
