|
* \brief Platform feature descriptions and dependency checks
|
|
*
|
|
* This file explains the purpose of all of the HAVE_* features
|
|
* and provides logical checks for features that depend on other features.
|
|
*
|
|
* A platform defines the features it wants in src/platform/<plat>/pmfeatures.py
|
|
* A tool generates C HAVE_* definitions in pmfeatures.h from pmfeatures.py.
|
|
*
|
|
*
|

* HAVE_PRINT
|
|
* ----------
|
|
*
|
|

|
|
* printing of the object.
