Updates #3937.
|
|
This fixes an issue with the latest tool chain which adds the default
linker script in the endfile specification.
Update #3250.
|
|
Adjust build support files to new directory layout.
This patch is a part of the BSP source reorganization.
Update #3285.

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.

Included variants:
tms570ls3137_hdk_intram - place code and data into internal SRAM
tms570ls3137_hdk_sdram - place code into external SDRAM and data to SRAM
tms570ls3137_hdk - variant prepared for stand-alone RTEMS aplication
stored and running directly from flash. Not working yet.
Chip initialization code not included in BSP.
External startup generated by TI's HalCoGen was used for
testing and debugging.

Patch version 2
- most of the formatting suggestion applied.
- BSP converted to use clock shell
- console driver "set attributes" tested. Baudrate change working
Patch version 3
- more formatting changes.
- removed leftover defines and test functions
Todo:
refactor header files (name register fields)

Implemented so far:
- nocache heap for uncached RAM
- basic timer
- level 1 cache handling for arm cache controller
in arm-cache-l1.h
- level 2 L2C-310 cache controller
- MMU
- DWMAC 1000 ethernet controller
- basic errata handling
- smp startup for second core

file.
|
|
* bsp_specs: Remove -Qy from *link.
