2008-07-21 Till Straumann * startup/bspstart.c: Removed SPRG0 warning - this BSP is OK. Use interrupt stack limits from linker script. No need to reserve space beyond '_end'. linkcmds now reserves space below '_end'. Use low-level exception handling support from new-exceptions/bspsupport. 2008-07-21 Till Straumann * 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). 2008-07-21 Till Straumann * startup/linkcmds: fixed sdata/sbss areas -- these must be contiguous for SVR4 complicant access via R13. Use kludged layout so that sbss, bss, sbss2 are all contiguous and zeroed by dlentry.S. Provide _SDA_BASE_ and _SDA2_BASE_ for loading R13 (and R2 if anyone wants to use EABI). Make sure interrupt stack is never in heap area by moving it below '_end'. Provide symbols for start + end of interrupt stack. 2008-07-21 Till Straumann * console/consolelite.c: use base address from RTEMS_XPARAMETERS_H rather than hardcoded hex number. 2008-05-15 Joel Sherrill * 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. 2008-05-14 Joel Sherrill * Makefile.am: Rework to avoid .rel files. 2008-05-12 Joel Sherrill * Makefile.am, 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. 2008-03-03 Joel Sherrill * startup/linkcmds: Add wildcard to gcc_except_table section so programs compiled with gcc 4.3.x can link. 2007-12-11 Joel Sherrill * README, include/bsp.h, startup/bspstart.c: Eliminate copies of the Configuration Table. Use the RTEMS provided accessor macros to obtain configuration fields. 2007-12-10 Till Straumann * irq/irq_init.c: renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR to be closer to 'official' nomenclature. 2007-12-04 Joel Sherrill * 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. 2007-12-03 Joel Sherrill * 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. 2007-11-30 Till Straumann * startup/bspstart.c: removed bsp_exceptions_in_RAM 2007-11-30 Till Straumann * irq/irq.h, irq/irq_init.c: Removed the definition of ASM_IRQ_VECTOR_BASE; this symbol was only use to initialize the irqBase member of the rtems_irq_global_settings struct. However, irqBase is an rtems_irq_symbolic_name, so using BSP_LOWEST_OFFSET is more appropriate. 2007-11-28 Joel Sherrill * startup/bspstart.c: Now compiles and links. 2007-11-28 Joel Sherrill * startup/bspstart.c: Eliminate PowerPC specific elements from the CPU Table. They have been replaced with variables named bsp_XXX as needed. 2007-11-07 Joel Sherrill * aclocal.m4: Removed. Is automatically generated by bootstrap. 2007-10-02 Jukka Pietarinen * startup/linkcmds: Move definition of _end so memory is not corrupted. 2007-09-12 Joel Sherrill PR 1257/bsps * irq/irq_init.c: Code outside of cpukit should use the public API for rtems_interrupt_disable/rtems_interrupt_enable. By bypassing the public API and directly accessing _CPU_ISR_Disable and _CPU_ISR_Enable, they were bypassing the compiler memory barrier directive which could lead to problems. This patch also changes the type of the variable passed into these routines and addresses minor style issues. 2007-09-11 Joel Sherrill * Makefile.am, include/bsp.h: Do not include networking drivers if networking is disabled. 2007-09-10 Joel Sherrill * network/xiltemac.c: Remove duplicate prototype. 2007-08-09 Thomas Doerfler * network/xiltemac.c: applied patch from Robert Grimes to correctly set the link speed to 100MBit 2007-07-27 Thomas Doerfler * linkcmds: removed superfluous bss section 2007-07-27 Thomas Doerfler * autom4te.cache/, network.old/: Removed. 2007-07-10 Thomas Doerfler * startup/linkcmds.dl: Removed. 2007-07-05 Thomas Doerfler * include/bsp.h: Added bsp/vectors.h and bsp/irq.h to list of included headers. 2007-07-05 Thomas Doerfler * opbintctrl/opbintctrl.c: Removed obsolete code. 2007-07-05 Joel Sherrill * .cvsignore: New file. 2007-04-1 Thomas Doerfler * bsp_specs, bsp_specs.dl, ChangeLog, configure.ac, * console/consolelite.c, dlentry/dlentry.S, include/bsp.h, * include/coverhd.h, include/opbintctrl.h, include/tm27.h, * include/xparameters_dflt.h, irq/irq.h, irq/irq_init.c, * Makefile.am, network/xiltemac.c, network/xiltemac.h, * opbintctrl/opbintctrl.c, preinstall.am, README, * startup/bspclean.c, startup/bspstart.c, startup/linkcmds, * startup/linkcmds.dl, startup/setvec.c; integration of virtex BSP into RTEMS source tree
