2000-08-01Patch rtems-rc-20000801-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-2/+2
that switches the sparc from targopts.h to cpuopts.h.
2000-07-27Port of RTEMS to the ARM processor family by Eric ValetteJoel Sherrill12-0/+1771
<valette@crf.canon.fr> and Emmanuel Raguet <raguet@crf.canon.fr> of Canon CRF - Communication Dept. This port includes a basic BSP that is sufficient to link hello world.
2000-07-26Port of RTEMS to the Texas Instruments C3x/C4x DSP families includingJoel Sherrill5-2/+10
a BSP (c4xsim) supporting the simulator included with gdb. This port was done by Joel Sherrill and Jennifer Averett of OAR Corporation. Also included with this port is a space/time optimization to eliminate FP context switch management on CPUs without hardware or software FP. An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8) on this CPU. This required addressing alignment checks and assumptions as well as fixing code that assumed sizeof(unsigned32) == 4.

2000-07-24Use bitwise and not cast to unsigned16 to remove upper bits.Joel Sherrill2-2/+6
2000-07-17Make _ISR_Dispatch global.Joel Sherrill1-0/+1
2000-07-17Update from Philip Quaife <rtemsdev@qs.co.nz> that was hand-merged.Joel Sherrill2-34/+75
This update addresses the following: + the ISR enable/disable/flash macros now work with old gcc versions. + the UI CCR bits are now masked since other example code did so + _ISR_Dispatch disables interrupts during call setup Together these removed the instabilities he was seeing.
2000-07-11Removed no cpu references.Joel Sherrill12-15/+15
2000-07-11Reworked score/cpu/sparc so it can be safely compiled multilib. AllJoel Sherrill10-127/+32
routines and structures that require CPU model specific information are now in libcpu. This primarily required moving erc32 specific information from score/cpu files to libcpu/sparc and the erc32 BSP.
2000-07-11Added Hitachi H8/300 to the list of CPUs that should be OK withJoel Sherrill1-0/+1
using cpuopts.h and not targopts.h.
2000-07-11Reworked score/cpu/i960 so it can be safely compiled multilib. AllJoel Sherrill5-533/+31
routines and structures that require CPU model specific information are now in libcpu. This required significant rework of the score/cpu header files and the creation of multiple header files and subdirectories in libcpu/i960.
2000-07-11Patch rtems-rc-20000711-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill8-9/+16
that decouples exec/ for the sh, m68k and i960 from targopts.h. NOTE: The change to system.h is a hack to enable cpuopts.h for some targets, but keep using targopts.h for others - I know it does *not* work for sparc, mips, i386 and ppc. This will have to be addressed as work continues on multilibing.
2000-07-10Patch rtems-rc-20000709-1.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-0/+6
that addresses aspects of the targopts.h multilib related issues. Changes: * Move targopts.h to libbsp/include, because the current targopts.h actually is a per-BSP-header and therefore can not stay below exec/. * Introduce an autoheader generated header file (exec/score/include/rtems/score/cpuopts.h), which shall take per-cpu configuration options only. * Move all autoconf-detectable/configure specified per-cpu option-defines from targopts.h to cpuopts.h. * Add Makefiles to the libbsp/shared directory hierarchy. Notes: * The new per-bsp targopts.h in libbsp includes the per-cpu cpuopts.h. This way, the new targopts.h is kept backward compatible to the old targopts.h and existing BSPs which (carelessly) include targopts.h (i386, ppc) should be kept working when using the multilib-disabled configuration scheme. * cpuopts.h is not yet complete, because the per-BSP make-targopts rules from custom/<BSP>.cfg files can not be applied to files below exec/ when building multilibs. * All files below exec/ should not include targopts.h anymore, but should include cpuopts.h instead. However, eliminating inclusion of targopts.h currently triggers further structural / header file inclusion related issues, because several ports apply BSP or CPU_MODEL specific defines from targopts.h below exec/
2000-07-07Moved old_exception_processing and new_exception_processing directoriesJoel Sherrill1-7/+1
from score/cpu to libcpu because the determination of which to use is based on RTEMS_CPU_MODEL. Thus it can not be determined based solely on multilib information.
2000-07-07Moved __RTEMS_APPLICATION__ conditional to include the use of theJoel Sherrill1-1/+1
static inline routine _CORE_mutex_Seize_interrupt_trylock since static routines are not included when in an application.
2000-07-06Added missing #endif's.Joel Sherrill2-3/+0
2000-07-06Corrected call to _CORE_mutex_Seize_interrupt_blocking.Joel Sherrill1-2/+5
2000-07-06Reimplemented _Core_MUTEX_Seize to return with interrupts disabledJoel Sherrill2-7/+119
if the mutex is successfully obtained.
2000-07-06Added _CORE_semaphore_Seize_isr_disable.Joel Sherrill1-0/+56
2000-07-06Added _Objects_Get_isr_disable prototype and added numerous comments.Joel Sherrill1-7/+18
2000-07-06Removed unnecessary parentheses.Joel Sherrill1-4/+4
2000-07-06Added objjectgetbyisr.cJoel Sherrill1-2/+3
2000-07-06The code that attempts to obtain a mutex has now been inlined. TheJoel Sherrill1-83/+7
code remaining here now only blocks.
2000-07-06Directly index local table to avoid error check.Joel Sherrill3-12/+10
2000-07-06New file. Convert ID to pointer and return with interrupts -- notJoel Sherrill1-0/+83
dispatching -- disabled.
2000-07-06Format of return line changed.Joel Sherrill1-3/+3
2000-07-03Interrupt stack is allocated in _ISR_Handler_initialization notJoel Sherrill8-8/+8
_Interrupt_Manager_initialization.
2000-07-03Added blocked_count field to allow for optimizations.Joel Sherrill2-2/+4
2000-07-03Changed extra_system_initialization_stack to extra_mpci_receive_server_stackJoel Sherrill1-1/+1
to be consistent with other ports.
2000-06-29This is the initial addition of the port of RTEMS to theJoel Sherrill12-0/+1979
Hitachi H8 family. This port was done by Philip Quaife <philip@qs.co.nz> of Q Solutions and sponsored by Comnet Technologies Ltd. The port was done based on RTEMS 3.5.1 to a Hitach H8300H. The port was updated to RTEMS 4.5 style Makefiles/configure by Joel Sherrill <joel@OARcorp.com>. While doing this Joel added support for the h8300-rtems to binutils, gcc, newlib, and gdb. NOTE: Philip submitted a BSP for a Hitachi evaluation board which is being merged as a separate entity.
2000-06-29Added RTEMS_CPU_HAS_16_BIT_ADDRESSES constant to disable codeJoel Sherrill1-0/+4
that breaks when the target has 16 bit address space. One of the H8 multilibs is a 16-bit address space CPU. When a real attempt is made to support this CPU model, the code that assumes an address is 32 bits will have to change. This constant is probably not flagging all impacted code.
2000-06-15Remove pragma align 4Joel Sherrill1-2/+0
2000-06-14Patch rtems-rc-20000614-sh.tar.gz from Ralf CorsepiusJoel Sherrill2-11/+12
<corsepiu@faw.uni-ulm.de> that migrates the SH port to multilib'ing. This patch involved moving a number of files in the CVS repository, adding new files, and deleting files from their previous location. Ralf gave good instructions (not repeated here) and here are his notes: Note 1: In this version, I did not change the installation points of the headers which are moved inside of the source-tree. This is a temporary hack for not breaking compatibility with 4.5 based BSPs, but will probably not last once having real multilibs (We would have include file conflicts when several BSPs/CPU_MODELS share a common installation prefix). Note 2: I hope not to have broken too much, but I would not be astonished if something goes wrong. Note 3: There are more patches to come :)
2000-06-14Moved PowerPC cache management code to libcpu. Also compiledJoel Sherrill1-151/+0
mpc8xx libcpu support for the first time and remove includes of bsp.h, references to BSP_Configuration, and Cpu_table. All of these can be obtained directly from RTEMS now.
2000-06-14Thread iterator and libgjc support submitted too early.Joel Sherrill3-61/+9
2000-06-13Added crude i960ka support.Joel Sherrill3-6/+38
2000-06-13Moved i386 and m68k cache management code to libcpu. EverythingJoel Sherrill2-306/+0
now is an implementation of the prototypes in rtems/rtems/cache.h. The libcpu/i386/wrapup directory is no longer needed. The PowerPC needs this done to it.
2000-06-12Patch from John Cotton <john.cotton@nrc.ca>, Charles-Antoine GauthierJoel Sherrill8-19/+603
<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart <Darlene.Stewart@nrc.ca> to add support for a number of very significant things: + BSPs for many variations on the Motorola MBX8xx board series + Cache Manager including initial support for m68040 and PowerPC + Rework of mpc8xx libcpu code so all mpc8xx CPUs now use same code base. + Rework of eth_comm BSP to utiltize above. John reports this works on the 821 and 860

adds .cvsignore.
2000-03-01Added routines to get and set C3x IOF register. The code is conditionallyJoel Sherrill2-26/+142
compiled and there is no comparable code for the C4x.
2000-02-29BSP now compiles and links with CAVSL board information. This includesJoel Sherrill1-3/+3
linkcmds updated, simio references removed, and switch to libchip for serial ports from simio. Added a MEMORY_MAP file to capture information about the various addresses on this board. In addition, many of the beta patches are now included.
2000-02-22New port of RTEMS to TI C3x and C4x.Joel Sherrill12-0/+3149
2000-02-08Patches rtems-rc-20000204-0.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1-1/+0
that contains: * Removes remaining (now illegal) references to $(SRC) from a couple of Makefile.ams * Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in * Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR from most configure scripts, i.e. LIBCDIR becomes less visible) * Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to libbsp/*/configure.ins (A minor bug in previous implementations, which only has an impact when switching to GNU/Cygnus canonicalization) * Cleans up several bogus comments. * Removes MKLIB * Switches the version number to 4.5.0 (for testing version number handling)
