* Makefile.am, configure.ac, include/bsp.h, startup/linkcmds: Use shared bsp_get_work_area() in its own file and rely on BSP Framework to perform more initialization. After factoring this out, it turned out that all SuperH BSPs has the same bsp_start() implementation so this was made shared. * startup/bspstart.c: Removed.

* startup/bspstart.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.

* 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.

* 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.

* Makefile.am, 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 clicks_per_microsecond field in the SuperH CPU Table and define another mechanism for drivers to obtain this information.

* startup/bspstart.c: As part of fixing PR281 on gensh4, a review of all calls to bsp_libc_init() resulted in some cleanup here.

* scitab/Makefile.am, startup/bspstart.c, configure.in: Removed rest of make-target-options and moved them to BSP configure options.

* startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h, and libcsupport.h moved from libc to lib/include/rtems and now must be referenced as <rtems/XXX.h>. Header file order was cleaned up while doing this.

1999-11-18Patch from "John M. Mills" <jmills@tga.com> with subsequent cleanup fromJoel Sherrill1-2/+2
Ralf Corsepius <corsepiu@faw.uni-ulm.de> that adds initial Hitachi SH-2 support to RTEMS. Ralf's comments are: Changes: ------ 1. SH-Port: * Many files renamed. * CONSOLE_DEVNAME and MHZ defines removed from libcpu. * console.c moved to libbsp/sh/shared, build in libbsp/sh/<BSP>/console applying VPATH. * CONSOLE_DEVNAME made BSP-specific, replacement is defined in bsp.h * MHZ define replaced with HZ (extendent resolution) in custom/*.cfg * -DHZ=HZ used in bspstart.c, only * Makefile variable HZ used in bsp-dependent directories only. 2. SH1-Port * clock-driver rewritten to provide better resolution for odd CPU frequencies. This driver is only partially tested on hardware, ie. sightly experimental, but I don't expect severe problems with it. * Polling SCI-driver added. This driver is experimental and completly untested yet. Therefore it is not yet used for the console (/dev/console is still pointing to /dev/null, cf. gensh1/bsp.h). * minor changes to the timer driver * SH1 specific delay()/CPU_delay() now is implemented as a function 3. SH2-Port * Merged * IMO, the code is still in its infancy. Therefore I have interspersed comments (FIXME) it for items which I think John should look after. * sci and console drivers partially rewritten and extended (John, I hope you don't mind). * Copyright notices are not yet adapted
1998-11-19Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1-1/+1
Here is a cosmetic patch which corrects a few spelling problems in parts written by me. Apparently, I must have written these under the influence of ether (:-)
1998-04-15Numerous changes which in total greatly reduced the amount of sourceJoel Sherrill1-25/+1
code in each BSP's bspstart.c. These changes were: + confdefs.h now knows libio's semaphore requirements + shared/main.c now copies Configuration to BSP_Configuration + shared/main.c fills in the Cpu_table with default values This removed the need for rtems_libio_config() and the constant BSP_LIBIO_MAX_FDS in every BSP. Plus now the maximum number of open files can now be set on the gcc command line.
1998-04-15Transitioned to shared bsp_libc_init() and cleaned up comments.Joel Sherrill1-45/+11
1998-04-15Per suggestion from Eric Norum, went from one initial extension setJoel Sherrill1-13/+0
to multiple. This lets the stack check extension be installed at system initialization time and avoids the BSP having to even know about its existence.
1998-04-14Stack checker extension now accounted for in confdefs.hJoel Sherrill1-8/+0
1998-04-14Now accounts for region used by RTEMS malloc and extension usedJoel Sherrill1-22/+0
by newlib.
1998-03-30Moved bsp_postdriver_hook() to a shared file and made it a commonJoel Sherrill1-27/+3
component.
1998-03-21Switch to using a shared main() for all of the embedded BSPsJoel Sherrill1-20/+1
based on the GNU tools. This usually involved correcting the type of bsp_start(), bsp_cleanup(), adjusting the start code to call the right start routine (the shared boot_card()), and then removing code from bsp_start() which was performed in the new boot_card()/main() path.
1998-03-20SH port submitted from Ralf Corsepius <corsepiu@faw.uni-ulm.de>.Joel Sherrill1-33/+43
1998-02-17updated copyright to 1998Joel Sherrill1-1/+1
1997-10-08Fixed typo in the pointer to the license terms.Joel Sherrill1-2/+2
1997-07-09Repository damaged -- file re-addedJoel Sherrill1-2/+15
1997-04-22headers updated to reflect new style copyright notice as partJoel Sherrill1-5/+5
of switching to the modified GNU GPL.
1997-01-29All RTEMS system call implementation renamed to be __rtems_*.Joel Sherrill1-4/+4
1996-05-28added initial posix configuration supportJoel Sherrill1-1/+1
1996-02-21Dispersal of internal thread handler resulted in the SYSI task beingJoel Sherrill1-1/+1
only required in a multiprocessor system. It was replace by the MPCI Receive Server. As a result, the CPU Table field for extra stack for the SYSI task was changed to be extra stack for the MPCI Receive Server.
1995-10-30SPARC port passes all testsJoel Sherrill1-4/+7
1995-09-19Minor bug fixes to get all targets compilable and running. TheJoel Sherrill1-5/+31
single biggest changes were the expansion of the workspace size macro to include other types of objects and the increase in the minimum stack size for most CPUs.
1995-09-11The word "RTEMS" almost completely removed from the core.Joel Sherrill1-4/+66
Configuration Table Template file added and all tests modified to use this. All gvar.h and conftbl.h files removed from test directories. Configuration parameter maximum_devices added. Core semaphore and mutex handlers added and RTEMS API Semaphore Manager updated to reflect this. Initialization sequence changed to invoke API specific initialization routines. Initialization tasks table now owned by RTEMS Tasks Manager. Added user extension for post-switch. Utilized user extensions to implement API specific functionality like signal dispatching. Added extensions to the System Initialization Thread so that an API can register a function to be invoked while the system is being initialized. These are largely equivalent to the pre-driver and post-driver hooks. Added the Modules file oar-go32_p5, modified oar-go32, and modified the file make/custom/go32.cfg to look at an environment varable which determines what CPU model is being used. All BSPs updated to reflect named devices and clock driver's IOCTL used by the Shared Memory Driver. Also merged clock isr into main file and removed ckisr.c where possible. Updated spsize to reflect new and moved variables. Makefiles for the executive source and include files updated to show break down of files into Core, RTEMS API, and Neither. Header and inline files installed into subdirectory based on whether logically in the Core or a part of the RTEMS API.
