However, I don't understand enough about the configure.ac syntax and its applicability to figure out how to parameterize the makefile.ac. Could someone please help me out with a tutorial, primer or pointer? Also, is it a reasonable model to expect a user to modify configure.ac to indicate where to find 3rd party software the BSP needs to build against, or should this come from the existence and value of an environment variable or some such? Another place where I guess one could place these kinds of things is in <bsp>/make/custom/<file>.cfg, but I haven't figured out how to specify which of these to use to $RTEMS_ROOT/src/configure.
You can use BSP options in a configure.ac file for this:
RTEMS_BSPOPTS_HELP([LPC24XX_CCLK],[CPU clock in Hz])
If your BSP needs third party libraries, then you should check in the configure
script that these libraries are available and set the appropriate flags.
