->Description</H2
-><P
->Some packages such as device drivers and HAL packages are
-hardware-specific, and generally it makes no sense to add such
-packages to a configuration unless the corresponding hardware is
-present on your target system. Typically hardware package selection
-happens automatically when you select your target. The <SPAN
-CLASS="PROPERTY"
->hardware</SPAN
->
-property can be used in the body of a <TT
-CLASS="LITERAL"
->cdl_package</TT
-> command to
-indicate that the package is hardware-specific.</P

-CLASS="NOTE"
-><P
-><B
->Note: </B
->At the time of writing the <SPAN
-CLASS="PROPERTY"
->hardware</SPAN
-> property is largely ignored by
-the configuration tools, but this may change in future. Amongst other
-possible changes, for hardware-specific packages such as device
-drivers and HAL packages, the current scheme of generating a
-configuration header file name based purely on the package name may be
-abandoned. Instead all hardware packages would send their
-configuration data to a single header file, <TT
-CLASS="FILENAME"
->pkgconf/hardware.h</TT
->. This would make it
-easier for code to obtain details of the current hardware, but
-obviously there are compatibility issues. For now it is recommended
-that all hardware packages specify their configuration header file
-explicitly.</P
