A "make dist" is not supported. So, it makes no sense to have pure "make
dist" related stuff in the Makefile.am.

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.

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.

* Makefile.am: Remove references to non-existing files.
|
| |
|
| |
|
|
|
|
|
| |
* Makefile.am, start/preload.S: moved preload.S
to ../shared/start.
|
|
|
|
|
|
| |
* shared/motorola/vpd.c, shared/motorola/vpd.h:
added code (originally developed for 'beatnik')
to read MotLoad VPD data from i2c eeprom.
|
|
|
|
|
|
| |
* Makefile.am: merged shared/vme/vme_universe.c and
shared/vme/vme_universe_dma.c into one file.
Added support for Tsi148 driver (DMA).

* Makefile.am, shared/flash, shared/flash/flash.c,
shared/flash/flashPgm.h, shared/flash/flashPgmPvt.h,
shared/flash/intelFlash.c, shared/flash/spansionFlash.c:
Added flash programmer API, implementation and chip drivers
for some intel + spansion flash chips (as found on mvme5500,
mvme6100 and mvme3100 boards).
A more appopriate place would probably be libchip but
I don't know if the API is acceptable and if the implementation
is generic enough (e.g., no CFI support) so I leave it here
for now.

* Makefile.am, motorola_powerpc/Makefile.am,
* shared/pci/detect_raven_bridge.c, Makefile.am,
* shared/pci/generic_clear_hberrs.c: separated the generic
version of _BSP_clear_hostbridge_errors() into its own
file.

* shared/vme/VMEConfig.h:
Added more comments about the semantics of the various
symbols BSPs should define in this file.
Removed declarations of BSP_VMEInit(), BSP_VMEIrqMgrInstall().
* shared/vme/vmeconfig.c: declare BSP_VMEInit(),
BSP_VMEIrqMgrInstall() here.
* Makefile.am, shared/vme/README,
* shared/vme/vme_universe_dma.c (added): Added glue code
implementing the VMEDMA.h API using the vmeUniverse driver.

* ep1a/Makefile.am, ep1a/preinstall.am,
* motorola_powerpc/Makefile.am, motorola_powerpc/preinstall.am,
* score603e/Makefile.am, score603e/preinstall.am,
* shared/vme/VME.h:
moved VME.h from libbsp/powerpc/shared/vme to
libbsp/shared/vmeUniverse; eventually, this (and other)
VME API headers should migrate to cpukit.

* shared/vme/README, shared/vme/vme_universe.c: New files.
* Makefile.am, motorola_powerpc/Makefile.am, mvme5500/vme/vmeconfig.c,
shared/vme/VME.h, shared/vme/VMEConfig.h, shared/vme/vmeconfig.c:
Several VME related upgrades and fixes, hopefully addressing PR#835:
Separated API, API-implementation by a specific VME bridge driver and
BSP-specific configuration of the driver into different files,
describing their purpose in a README. All of these changes use the
upgraded vmeUniverse.c driver.

* shared/irq/openpic_i8259_irq.c: New file.
* ChangeLog, Makefile.am, motorola_powerpc/ChangeLog,
motorola_powerpc/Makefile.am, shared/irq/irq.c, shared/irq/irq.h,
shared/irq/irq_asm.S, shared/irq/irq_init.c: Separated openpic/i8259
specifica from generic irq handling into openpic_i8259_irq.c; added
some compilation conditionals to help BSPs without ISA to omit ISA
interrupts and calling i8259 code.

* shared/startup/pretaskinghook.c, shared/startup/zerobss.c: New files.
* Makefile.am, shared/startup/bspstart.c: Split
pretaskinghook and zerobss into separate, reusable files; Fixed
#PR837 (set exception in ram flag before initializing exceptions);
Setup DBATs early, they are needed to access peripherals (Allows
mvme2100 to use MMU); moved VME initialization into pretasking hook
so that shared interrupts can be used for VME [shared IRQ facility
needs functional workspace].

which converts the PowerPC BSPs to configuration and more automake.
* Besides adding partial automake support, rsp converting all powerpc
BSPs to make them compliant to the new configuration scheme, this patch
attempts to fix several configuration bugs in powerpc related Makefiles.
