| |
From: Kan Liang <kan.liang@linux.intel.com>
Now, "--phys-data" is the only option which impacts the output format. A simple "if else" is enough to handle the option. But there will be more options added, e.g. "--data-page-size", which also impact the output format. The code will become too complex to be maintained.
Divide the big printf into several small pieces. Output the specific piece only if the related option is applied.
No functional change.
