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.

section and a nonempty TLS BSS section.

Changed console driver to use interrupts instead of polling.
Change to avoid overwriting CPU32Bug interrupt vector when setting up the Sci interrupt handler.
Fixed type for boolean flag in bsp.h.
Changed mrm332.h to use 25Mhz clock.
Fixes to mrm332.cfg to use correct mcpu32 value for RTEMS_CPU_MODEL instead of m68332 which is no longer supported.
Added -mcpu=cpu32 to compiler options.
Removed broken ROM linker script and replaced broken RAM linker script with working ROM linker script.
Removed no longer required file except_vect_332_ROM.S.
Enabled 0xbeefbeef magic string in start.S to allow MRM version of CPU32Bug to auto run RTEMS.
Removed old code from start.S
Changed compiler optimization flag to optimize for size.

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.

* startup/bsppredriverhook.c: Remove warnings.
|
|
|
|
|
| |
* start/start.S, startup/start_c.c: Update for boot_card command
line change.
|
|
|
|
|
| |
* Makefile.am: BSP specific bsp_cleanup() is a dupe of a shared one.
* startup/bspclean.c: Removed.
|
|
|
|
|
| |
* Makefile.am, startup/linkcmds, startup/linkcmds_ROM: Use top level
shared bsp_get_work_area() implementation.
|
|
|
|
| |
* startup/bspstart.c: Removed.
|
|
|
|
|
|
|
|
| |
* Makefile.am, configure.ac, clock/ckinit.c, startup/linkcmds,
startup/linkcmds_ROM: Add use of bsp_get_work_area() in its own file
and rely on BSP Framework to perform more initialization. Remove
unnecessary includes of rtems/libio.h and rtems/libcsupport.h.
* startup/bsppredriverhook.c: New file.
|
|
|
|
|
| |
* console/sci.c, startup/bspstart.c, startup/start_c.c,
timer/timer.c: Add missing prototypes.
|
|
|
|
|
|
|
|
|
|

* console/console.c, startup/bspstart.c: Refactored and renamed
initialization routines to rtems_initialize_data_structures,
rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
rtems_initialize_start_multitasking. This opened the sequence up so
that bootcard() could provide a more robust and flexible framework
which is easier to explain and understand. This also lays the
groundwork for sharing the division of available memory between the
RTEMS workspace and heap and the C library initialization across all
BSPs.
|
|
|
|
|
|
| |
* startup/linkcmds, startup/linkcmds_ROM: Add wildcard to
gcc_except_table section so programs compiled with gcc 4.3.x can
link.
|
|
|
|
|
|
| |
* clock/ckinit.c, include/bsp.h, startup/bspstart.c: Eliminate copies
of the Configuration Table. Use the RTEMS provided accessor macros to
obtain configuration fields.
|
|
|
|
|
|
| |
* include/bsp.h, startup/bspstart.c: Move interrupt_stack_size field
from CPU Table to Configuration Table. Eliminate CPU Table from all
ports. Delete references to CPU Table in all forms.
|
|
|
|
|
|
|
|
|
| |
* startup/bspstart.c: Moved most of the remaining CPU Table fields to
the Configuration Table. This included pretasking_hook,
predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
extra_mpci_receive_server_stack, stack_allocate_hook, and
stack_free_hook. As a side-effect of this effort some multiprocessing
code was made conditional and some style clean up occurred.
|
|
|
|
|
| |
* startup/bspstart.c: Eliminate the interrupt_vector_table field in the
m68k CPU Table since it is never read.
|
|
|
|
| |

|
|
|
|
|
|
| |
* console/console.c, console/sci.c, console/sci.h, spurious/spinit.c,
startup/bspclean.c, startup/start_c.c: Convert C++ style comments to
C style.
|
|
|
|
|
| |
* startup/linkcmds, startup/linkcmds_ROM: Add sections required by
newer gcc versions.
|
|
|
|
|
| |
* startup/linkcmds, startup/linkcmds_ROM: Add new bss sections .bss.*
and .gnu.linkonce.b*.
