Hi,

Sorry for the delay in starting with this.

I went through a few BSP cfg files, for example, the leon3

Are we planning to write something like this for each BSPs ? ...
=================
prefix=@prefix@
exec_prefix=@exec_prefix@
libdir=@libdir@
includedir=@includedir@

CFLAGS=@CFLAGS@
RTEMS_BSP=@RTEMS_BSP@

Name: @RTEMS_BSP@
Version: @VERSION@
Description: RTEMS BSP @RTEMS_BSP@ config
Libs:
Cflags: -O2 -g -ffunction-sections -fdata-sections
=================

every BSP configuration file includes default.cfg, how will this be
included in the *.pc files?
