Close #3250.
Close #4081.

Updates #3425.
|

This AC_CONFIG_SRCDIR() is just a sanity check in this insane build
system. Since all content of
c/src/lib/libbsp/@RTEMS_CPU@/@RTEMS_BSP_FAMILY@ is bound to be moved it
makes no sense to keep it.
This patch is a part of the BSP source reorganization.
Update #3285.

|
The subdir-objects do not work currently due to BSP sources in bsps and
c and the existing build tree layout.
Update #3387.

This option silences warning with automake-1.16.1 allowing us to
upgrade to that version.
This change has been tested with automake-1.12.6 and automake-1.16.1.
It seems version 1.16.1 configures slower than 1.12.6 for the same
source and BSP. The newer versions is 6 second slower.

Provide HAS_NETWORKING and HAS_SMP Automake conditionals for all BSPs.

A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.
Update #3254.

Remove BSP-specific defaults for RTEMS_BSP_CLEANUP_OPTIONS to simplify
the BSP configuration and documentation. Change defaults to:
BSP_PRESS_KEY_FOR_RESET=0
BSP_RESET_BOARD_AT_EXIT=1
BSP_PRINT_EXCEPTION_CONTEXT=1

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

This commit covers at least PR2020, 2022, and 2023. This
patch adds all of the code for both BSPs, modifications
to libcpu/powerpc for the ppc440, and some updates to the
BSPs from follow up review and testing.
These BSPs should be good baselines for future development.
The configurations used by Ric are custom and have a non-standard
NIC. They also do not have a UART. Thus the current console
driver just prints to a RAM buffer.
The NIC and UART support are left for future work. When the UART
support is added, moving the existing "to RAM" console driver to
a shared location is likely desirable because boards with no debug
UART port are commonly deployed. This would let printk() go to RAM.

string constants.
