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.

* make/custom/dp2.cfg, startup/linkcmds.dp2: New files.
* Makefile.am, preinstall.am: Reflect change above. Install
<bsp/utility.h>. Install BestComm header files.
* configure.ac: Changed BSP options.
* include/mpc5200.h: Added module structures and register defines.
* bestcomm/bestcomm_api.c, bestcomm/bestcomm_api.h,
bestcomm/bestcomm_glue.c, bestcomm/bestcomm_glue.h,
bestcomm/bestcomm_priv.h, bestcomm/load_task.c,
bestcomm/tasksetup_bdtable.c, bestcomm/task_api/bestcomm_cntrl.h: C++
compatibility. Use special heap to manage the SRAM region. Use
interrupt extension API. Fixed warnings.
* console/console.c: Fixed console registration. Fixed warnings.
Added GPS module registration.
* ide/pcmcia_ide.h: Fixed clock value macros.
* ide/pcmcia_ide.c: Update for BestComm API changes.
DP2 specific initialization. Removed zero loop in PIO receive
function.
* include/bsp.h: Added DP2 variant. Removed obsolete defines.
* include/mscan-base.h, mscan/mscan-base.c: Use volatile qualifier.
Format.
* irq/irq.c: Fixed peripheral interrupt handling.
* network_5200/network.c: Update for BestComm API changes.
* start/start.S: U-Boot fixes.
* startup/cpuinit.c: Enable write-back cache strategy. Added special
memory regions.
* startup/linkcmds.brs5l: Fixed memory size.

|
* include/irq-config.h: Removed file.
* Makefile.am, preinstall.am: Reflect change above. Added interrupt
support modules.
* include/irq.h: Moved defines from 'include/irq-config.h'.
* include/mpc5200.h: Added GPIO PIN defines.
|
|
* include/mpc5200.h: Expand tabs.
|
|
* include/mpc5200.h: Fix typo.
|
|
* include/mpc5200.h: Fix constants off by one nibble.
|
|
* include/mpc5200.h: Added some simple interrupt GPIO constants.
|

Add Embedded Planets EP5200 which is the same as the Freescale
5200Lite (a.k.a. IceCube) evaluation board.
* Makefile.am: Add linkcmds.ep5200.
Add -DMPC5200_BAPI_LIBC_HEADERS to remove some warnings in bestcomm.
* preinstall.am: Add linkcmds.ep5200.
* clock/clock.c: Correct math for prescaler/counter when bus speed
is high enough to require multiple passes of loop.
* console/console.c: Use same math for initial baud rate as when it
is changed via ioctl. When HAS_UBOOT is defined, initialize console
to the same baud as it was with U-Boot.
* include/bsp.h: Add EP5200 and console boot baud support.
* include/mpc5200.h: Spacing.
* startup/bspstart.c: If HAS_UBOOT and SHOW_MORE_INIT_SETTINGS are
both defined, dump the U-Boot BD info structure.
* vectors/vectors.S: ep5200 cannot use vectors segment. When loading
it, U-Boot freezes. Besides, U-Boot can automatically start the BSP
so we do not have to run from board reset.
* startup/linkcmds.ep5200: New file.
|
|
* include/mpc5200.h, network_5200/network.c: Convert C++ style comments
to C style.
