  • dlentry/dlentry.S: load R13 with _SDA_BASE_ so that SVR4-ABI access of short data area works. No support for R2/sdata2/eabi, so far but that would be easy (atm R2 is loaded with got address IIRC).
  • Property mode set to 100644

3        * dlentry/dlentry.S: load R13 with _SDA_BASE_ so that
4        SVR4-ABI access of short data area works. No support
5        for R2/sdata2/eabi, so far but that would be easy
6        (atm R2 is loaded with got address IIRC).

9
10        * startup/linkcmds: fixed sdata/sbss areas -- these
11        must be contiguous for SVR4 complicant access via R13.
12        Use kludged layout so that sbss, bss, sbss2 are all
13        contiguous and zeroed by dlentry.S.
14
15        Provide _SDA_BASE_ and _SDA2_BASE_ for loading R13 (and
16        R2 if anyone wants to use EABI).
17
18        Make sure interrupt stack is never in heap area by
19        moving it below '_end'.
20
21        Provide symbols for start + end of interrupt stack.
22

24
25        * console/consolelite.c: use base address from RTEMS_XPARAMETERS_H
26        rather than hardcoded hex number.

29
30        * startup/bspstart.c: Add capability for bootcard.c BSP Initialization
31        Framework to ask the BSP where it has memory for the RTEMS Workspace
32        and C Program Heap. These collectively are referred to as work area.
33        If the BSP supports this, then it does not have to include code to
34        split the available memory between the two areas. This reduces the
35        amount of code in the BSP specific bspstart.c file. Additionally, the
36        shared framework can initialize the C Library, call
37        rtems_debug_enable(), and dirty the work area memory. Until most/all
38        BSPs support this new capability, if the BSP supports this, it should
39        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
40        When the transition is complete, this autoconf macro can be removed.

43
44        * Makefile.am: Rework to avoid .rel files.
45
462008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
47
48        * Makefile.am, startup/bspstart.c: Refactored and renamed
49        initialization routines to rtems_initialize_data_structures,
50        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
51        rtems_initialize_start_multitasking. This opened the sequence up so
52        that bootcard() could provide a more robust and flexible framework
53        which is easier to explain and understand. This also lays the
54        groundwork for sharing the division of available memory between the
55        RTEMS workspace and heap and the C library initialization across all
56        BSPs.
57
582008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
59
60        * startup/linkcmds: Add wildcard to gcc_except_table section so
61        programs compiled with gcc 4.3.x can link.
62
632007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
64
65        * README, include/bsp.h, startup/bspstart.c: Eliminate copies of the
66        Configuration Table. Use the RTEMS provided accessor macros to obtain
67        configuration fields.
68
692007-12-10      Till Straumann <strauman@slac.stanford.edu>
70
71        * irq/irq_init.c:
72        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
73        to be closer to 'official' nomenclature.
74
752007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
76
77        * include/bsp.h, startup/bspstart.c: Move interrupt_stack_size field
78        from CPU Table to Configuration Table. Eliminate CPU Table from all
79        ports. Delete references to CPU Table in all forms.
80
812007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
82
83        * startup/bspstart.c: Moved most of the remaining CPU Table fields to
84        the Configuration Table. This included pretasking_hook,
85        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
86        extra_mpci_receive_server_stack, stack_allocate_hook, and
87        stack_free_hook. As a side-effect of this effort some multiprocessing
88        code was made conditional and some style clean up occurred.
89
902007-11-30      Till Straumann <strauman@slac.stanford.edu>
91
92        * startup/bspstart.c: removed bsp_exceptions_in_RAM
93
942007-11-30      Till Straumann <strauman@slac.stanford.edu>
95
96        * irq/irq.h, irq/irq_init.c: Removed the definition
97        of ASM_IRQ_VECTOR_BASE; this symbol was only use to
98        initialize the irqBase member of the rtems_irq_global_settings
99        struct. However, irqBase is an rtems_irq_symbolic_name,
100        so using BSP_LOWEST_OFFSET is more appropriate.
101
1022007-11-28      Joel Sherrill <joel.sherrill@OARcorp.com>
103
104        * startup/bspstart.c: Now compiles and links.
105
1062007-11-28      Joel Sherrill <joel.sherrill@OARcorp.com>
107
108        * startup/bspstart.c: Eliminate PowerPC specific elements from the CPU
109        Table. They have been replaced with variables named bsp_XXX as
110        needed.
111
1122007-11-07      Joel Sherrill <joel.sherrill@OARcorp.com>
113
114        * aclocal.m4: Removed. Is automatically generated by bootstrap.
115
1162007-10-02      Jukka Pietarinen <jukka.pietarinen@mrf.fi>
117
118        * startup/linkcmds: Move definition of _end so memory is not corrupted.
119
1202007-09-12      Joel Sherrill <joel.sherrill@OARcorp.com>
121
122        PR 1257/bsps
123        * irq/irq_init.c: Code outside of cpukit should use the public API for
124        rtems_interrupt_disable/rtems_interrupt_enable. By bypassing the
125        public API and directly accessing _CPU_ISR_Disable and
126        _CPU_ISR_Enable, they were bypassing the compiler memory barrier
127        directive which could lead to problems. This patch also changes the
128        type of the variable passed into these routines and addresses minor
129        style issues.
130
1312007-09-11      Joel Sherrill <joel.sherrill@OARcorp.com>
132
133        * Makefile.am, include/bsp.h: Do not include networking
134        drivers if networking is disabled.

141        * network/xiltemac.c:
142        applied patch from Robert Grimes to correctly set the link speed
143        to 100MBit
144
