BSP and Device Driver Development Guide
There is a file named Makefile.in in each directory of a BSP.
RTEMS uses the GNU autoconf automatic configuration package.
This tool specializes the Makefile.in files at the time that RTEMS
is configured for a specific development host and target. Makefiles
are automatically generated from the Makefile.in files. It is
necessary for the BSP developer to provide these files. Most of the
time, it is possible to copy the Makefile.in from another
similar directory and edit it.
The Makefile files generated are processed when building
RTEMS for a given BSP.
The BSP developer is responsible for generating Makefile.in
files which properly build all the files associated with their BSP.
There are generally three types of Makefiles in a BSP source tree:
