3        * bootcard.c: Special case for PowerPC: The interrupt disable
4        mask is stored in SPRG0.  It must be valid before we can use
5        rtems_interrupt_disable().
6
72008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
8
9        * include/irq-config.h, include/irq-generic.h,
10        src/irq-generic.c, src/irq-legacy.c: Generic BSP interrupt handler
11        support.
12
132008-06-04      Joel Sherrill <joel.sherrill@OARcorp.com>
14
15        * include/tm27.h: New file. Stub version of tm27 support.
16
172008-05-23      Till Straumann <strauman@slac.stanford.edu>
18
19        * vmeUniverse/VME.h: removed 'weak' attribute from
20        declaration of BSP_vme_config().
21
222008-05-22      Till Straumann <strauman@slac.stanford.edu>
23
24        * vmeUniverse/vmeUniverse.c: fixed compiler warning;
25        moved struct attributes as directed by gcc warning.
26
272008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
28
29        * bootcard.c: Add capability for bootcard.c BSP Initialization
30        Framework to ask the BSP where it has memory for the RTEMS Workspace
31        and C Program Heap. These collectively are referred to as work area.
32        If the BSP supports this, then it does not have to include code to
33        split the available memory between the two areas. This reduces the
34        amount of code in the BSP specific bspstart.c file. Additionally, the
35        shared framework can initialize the C Library, call
36        rtems_debug_enable(), and dirty the work area memory. Until most/all
37        BSPs support this new capability, if the BSP supports this, it should
38        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
39        When the transition is complete, this autoconf macro can be removed.
40        * bsppretaskinghook.c: New file.
41
422008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
43
44        * bootcard.c: Refactored and renamed initialization routines to
45        rtems_initialize_data_structures, rtems_initialize_before_drivers,
46        rtems_initialize_device_drivers, and
47        rtems_initialize_start_multitasking. This opened the sequence up so
48        that bootcard() could provide a more robust and flexible framework
49        which is easier to explain and understand. This also lays the
50        groundwork for sharing the division of available memory between the
51        RTEMS workspace and heap and the C library initialization across all
52        BSPs.
53
542008-05-06      Joel Sherrill <joel.sherrill@OARcorp.com>
55
56        * bootcard.c: Improve formatting and comments.
57
582008-03-20      Till Straumann <strauman@slac.stanford.edu>
59
60        * vmeUniverse/vmeTsi148.c: type of 5th argument
61        to pci_read_config_dword() is now uint32_t*.
62
632008-03-17      Till Straumann <strauman@slac.stanford.edu>
64
65        * vmeUniverse/vmeTsi148.c: Initialize VME Master
66        'VTON' timer and bus-release policy to less aggressive
67        values than the chip's defaults. The default VTON easily
68        overrides any settings used by the DMA engine.
69
702008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
71
72        * gdbstub/rtems-stub-glue.c: Update to use the new
73        rtems_object_get_name() service. This simplified the code a bit.
74
752008-01-22      Joel Sherrill <joel.sherrill@OARcorp.com>
76
77        * bootcard.c: Improve comments and clean up argc/argv order.
78
792007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
80
81        * bootcard.c, bsplibc.c: Eliminate copies of the Configuration Table.
82        Use the RTEMS provided accessor macros to obtain configuration
83        fields.
84
852007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
86
87        * bootcard.c: Move interrupt_stack_size field from CPU Table to
88        Configuration Table. Eliminate CPU Table from all ports. Delete
89        references to CPU Table in all forms.
90
912007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
92
93        * bsppredriverhook.c: New file.
94
952007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
96
97        * bootcard.c: Moved most of the remaining CPU Table fields to the
98        Configuration Table. This included pretasking_hook, predriver_hook,
99        postdriver_hook, idle_task, do_zero_of_workspace,
100        extra_mpci_receive_server_stack, stack_allocate_hook, and
101        stack_free_hook. As a side-effect of this effort some multiprocessing
102        code was made conditional and some style clean up occurred.
103
1042007-12-02      Till Straumann <strauman@slac.stanford.edu>
105
106        * vmeUniverse/vmeUniverse.c, vmeUniverse/vmeTsi148.c:
107        silenced compiler warnings caused by type changes
108        in byteorder.h (volatile unsigned * -> volatile uint32_t *)

117
1182007-06-20      Joel Sherrill <joel.sherrill@OARcorp.com>
119
120        * bsppost.c: Split open of the console from the standard BSP code so it
121        is easier to stub out.
122
1232007-05-10      Till Straumann <strauman@slac.stanford.edu>

135        * bootcard.c: RTEMS Workspace now defaults to not being zeroed. This
136        significantly speeds up boot time on targets not requiring memory to
137        be touched at boot time.

165
1662007-01-30      Till Straumann <strauman@slac.stanford.edu>
167
168        * vmeUniverse/README.porting, vmeUniverse/README.universe:
169        updated, added more information for BSP implementors.
170
171        * vmeUniverse/VMEDMA.h (added): VME DMA API definition.
172
173        * vmeUniverse/bspVmeDmaList.h (added), vmeUniverse/bspVmeDmaListP.h (added),
174        * vmeUniverse/bspVmeDmaList.c (added):
175        Driver-independent code for linked-list DMA (public + private headers,
176        implementation).
177
178        * vmeUniverse/vmeUniverseDMA.h (added), vmeUniverse/vmeTsi148DMA.h (added):
179        interface to new DMA features of drivers.
180
181        * vmeUniverse/vme_amd_defs.h: Added definition for data-width
182        hint bits (VME_MODE_DBWxx).
183
184
185        * vmeUniverse/vmeTsi148.c: added DMA support. Added support for
186        data-width hint/modifier bits.
187
188        * vmeUniverse/vmeUniverse.c, vmeUniverse/vmeUniverse.h:
189        Added support for data-width hint/modifier bits.
190        Added support for xxx_BLT, xxx_MBLT address modifiers.
191        Restrict DBW to 32 in non-MBLT modes (except single-beat;
192        a comment is in README.universe). Updated DMA support to
193        implement new VMEDMA.h API. Added support for non-incrementing
194        VME addresses. Restrict data width to 32 for single-beat AMs
195        when the universe would use MBLT for DMA.
196
1972007-01-19      Till Straumann <strauman@slac.stanford.edu>
198
199        * vmeUniverse/VME.h:
200        moved VME.h from libbsp/powerpc/shared/vme to
201        libbsp/shared/vmeUniverse; eventually, this (and other)
202        VME API headers should migrate to cpukit.

207        vmeUniverse/vmeUniverse.c, vmeUniverse/vmeUniverse.h,
208        vmeUniverse/vme_am_defs.h:
209        Added SLAC/Stanford Authorship Note / Copyright + Liability Disclaimer.
210
2112006-12-13      Till Straumann <strauman@slac.stanford.edu>
212
213        * vmeUniverse/vme_am_defs.h: Added address modifiers for 2eVME.
214        Added flags for 2eSST and DBW16.
215        * vmeUniverse/vmeUniverse.h: Removed AM definitions and include
216        vme_am_defs.h instead. Declare new routine vmeUniverseMapCRG().
217        Export 'irq manager' API only if __INSIDE_RTEMS_BSP__ defined. Renamed
218        'shared' argument to vmeUniverseInstallIrqMgrAlt() to 'flags' since
219        now more options are available.  Added new flag to install
220        'posted-write' workaround.
221        * vmeUniverse/vmeUniverse.c: Allow BSP to override BSP_PCI2LOCAL_ADDR()
222        macro. Data width of outbound port can now be restricted to 16-bit
223        (if new DBW16 flag set in address modifier). Added vmeUniverseMapCRG()
224        for mapping local registers onto VME. Interrupt manager now implements
225        a workaround (enabled at installation time) which flushes the
226        write-fifo after user ISR returns. This requires the universe's
227        registers to be accessible from VME (either CSR space or CRG mapped
228        to A16/A24/A32), though.
229        * vmeUniverse/vmeTsi148.h: vmeTsi148ClearVMEBusErrors() now returns
230        the fault address as a 32-bit address (not ulonglong anymore). The
231        driver only supports 32-bit addresses. Declare new routine
232        vmeTsi148MapCRG().  Export 'irq manager' API only if
233        __INSIDE_RTEMS_BSP__ defined.  Renamed 'shared' argument to
234        vmeTsi148InstallIrqMgrAlt() to 'flags' to allow more options to be
235        supported. Added comments explaining the 'posted-write' workaround
236        implemented by the interrupt manager.
237        * vmeUniverse/vmeTsi148.c: Clear 'SYSFAIL' during initialization.
238        Allow BSP to override BSP_PCI2LOCAL_ADDR() macro. Added support for
239        2eSST when configuring windows (untested - I have no 2eSST).
240        Added vmeTsi148MapCRG() for mapping local registers onto VME.
241        Implemented 'posted-write' workaround for interrupt manager
242        (consult source for details).

252        for the header to declare 'dump info'-style routine. This
253        is in order to avoid pulling in <stdio.h>.

2552006-11-17      Joel Sherrill <joel@OARcorp.com>
256
257        * clock_driver_stub.c, clockdrv_shell.c: Use common clock driver
258        template and eliminate all fast idle code specific to this BSP. This
259        eliminates a fair amount of code in the BSP clock driver and
260        bsp_startup. The LEON3 has to do a scan of the AMBA bus to find the
261        timer so I added the new hook Clock_driver_support_find_timer to
262        support this. In general, there was some clean up to the file headers
263        of various files.
