PR1797/bsps: Applied cleaned-up version of Kate's patch.
CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK is now a 'bspopts.h'
setting and as such configurable.

* shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Add use
of bsp_get_work_area() in its own file and rely on BSP Framework to
perform more initialization.
* shared/startup/bspgetworkarea.c: New file.
|
| |
|
|
|
|

|
|

* shared/startup/pretaskinghook.c: removed declaration
of BSP_vme_config() (which is already declared in
<bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
gcc doesn't seem to understand that the linker may
define this to be NULL... Silences a compiler warning
(and users can always provide an empty routine).

* shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
Initialization Framework to ask the BSP where it has memory for the
RTEMS Workspace and C Program Heap. These collectively are referred
to as work area. If the BSP supports this, then it does not have to
include code to split the available memory between the two areas.
This reduces the amount of code in the BSP specific bspstart.c file.
Additionally, the shared framework can initialize the C Library, call
rtems_debug_enable(), and dirty the work area memory. Until most/all
BSPs support this new capability, if the BSP supports this, it should
call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
When the transition is complete, this autoconf macro can be removed.

* shared/startup/pretaskinghook.c: install pointer
to rtems_malloc_sbrk_helpers_table. This (and derived)
BSPs rely on sbrk delivering even the first/initial
chunk of memory.
|
| |
|
|
|
|
| |
* shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
copies of the Configuration Table. Use the RTEMS provided accessor
macros to obtain configuration fields.
|
| |
|
|
|
|
| |
* shared/startup/pretaskinghook.c: Replaced inclusion of
<bsp/consoleIo.h> by <rtems/bspIo.> (for printk) and
made it conditional on #ifdef SHOW_MORE_INIT_SETTINGS.
|
| | |
|
|
|
* 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].
