| | | | | | | PR 288/rtems * irq/irq_asm.S, startup/bspstart.c: _ISR_Nest_level is now properly maintained and any BSP which does not do so will trip a panic in the shared code.

| | | | | | | | PR 415/bsps * pci/detect_raven_bridge.c, startup/bspstart.c: This patch reverts enabling MCP interrupts for the motorola_powerpc BSPs. REASON: pci config space scanning (as e.g. done by the DEC Ethernet driver) would raise machine check exceptions.

| | | | | | | | | | | PR 428/bsps PR 432/bsps * bootloader/pci.c: Re-instated code that prevents remapping small IO regions, which if remapped would cause i8259 registers to move out from under the #define'd base addresses. * startup/bspstart.c: Reduced BAT2 PCI memory allocation to 256 megs, I incorrectly had extended it which would cause problems with PCI devices that defined prefetchable memory.

| | | | | | | | | | | | | | | | | PR 405/bsps * bootloader/pci.c: Added support for configuring devices for pci busses > 0 * pci/pci.c, pci/pci.h: Added FixupPCI() to store vectors in the INTERRUPT_LINE register of pci devices any # of hops away from the host processor. * motorola/motorola.c, motorola/motorola.h: Added interrupt routing tables in support of FixupPCI. This is board-specific, each board will have to supply information for FixupPCI() to do anything for it. * startup/bspstart.c: Extended bat2 to cover entire PCI address space. * irq/irq.c, irq/irq.h: Added support for shared interrupts. Existing single hander vectors are undisturbed, a new function added to allow adding/removing handlers from a vector.

| | | | | | | PR 415/bsps * include/bsp.h, pci/detect_raven_bridge.c, startup/bspstart.c: Support enabling MCP exceptions on the host bridge. This can be used for memory probing on the VME bus.

| | | | | | | | | | | | | | | PR 356/bsps This patch makes RTEMS/powerpc/shared EABI compliant. * irq/irq_init.c, start/Makefile.am, start/start.S, startup/bspstart.c, startup/pgtbl_setup.c, vectors/vectors.h, vectors/vectors_init.c: zero_bss() should clear not only bss but sbss and sbss2 also (this is probably a bugfix, as sbss/sbss2 are probably used even if -msdata=eabi is not specified). * start/rtems_crti.S: New file which must be linked immediately after ecrti.o. rtems_crti.o contains a code snippet who lets __init() return immediately. Also, a new entry point '_init' to the C++ Ctors is generated for use by the RTEMS Thread_Handler.

| | | | | | | | PR 349/bsps * startup/pgtbl_setup.c, startup/pgtbl_activate.c: New files * startup/Makefile.am, startup/bspstart.c, startup/linkcmds: Let the powerpc/shared (+derived) BSPs use pagetable support from libcpu.

| | | | | | | | | | | PR 349/bsps * console/console.c, console/uart.c, console/uart.h: implement IOCTLs for the serial (UART) console to install/retrieve a BREAK-IRQ callback. The callback routine (if installed) is invoked from the UART ISR when a BREAK interrupt is detected. This can be used e.g. to enforce a "hotkey" reboot a la vxWorks Ctrl-X (although we use the serial line break condition) NOTE: The callback runs in ISR context.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bootloader/misc.c, console/Makefile.am, console/console.c, console/consoleIo.h, console/inch.c, console/polled_io.c, console/uart.c, console/uart.h, include/bsp.h, irq/Makefile.am, irq/irq.c, irq/irq.h, irq/irq_init.c, openpic/openpic.c, openpic/openpic.h, pci/Makefile.am, pci/pci.c, pci/pci.h, residual/Makefile.am, start/start.S, startup/bspstart.c, vectors/vectors.S, vectors/vectors.h, vectors/vectors_init.c: Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably with the goal to make it more flexible and reusable by other BSPs. The main strategies were: - eliminate hardcoded base addresses; devices use offsets and a BSP defined base address. - separate functionality into different files (e.g. reboot from inch.c to reboot.c) which can be overridden by a 'derived' BSP. - separate initialization code into separate files (e.g. PCI bridge detection/initialization was separated from the more generic PCI access routines), also to make it easier for 'derived' BSPs to substitute their own initialization code. There are also a couple of enhancements and fixes: - IRQ handling code now has a hook for attaching a VME bridge. - OpenPIC is now explicitely initialized (polarities, senses). Eliminated the implicit assumption on the presence of an ISA PIC. - UART and console driver now supports more than 1 port. The current maximum of 2 can easily be extended by enlarging a table (it would even be easier if the ISR API was not broken by design). - fixed polled_io.c so it correctly supports console on COM2 - fixed TLB invalidation code (start.S). - exception handler prints a stack backtrace. - added BSP_pciFindDevice() to scan the pci bus for a particular vendor/device/instance.

| | | | | | | | * startup/linkcmds: In support of gcc 3.1, added one of more of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*, .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*. Spacing corrections and direction of segments to memory regions may also have been addressed. This was a sweep across all BSPs.

| | | | | | | * 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.

| | | | | | * startup/linkcmds: Added lines so DWARF debug information would be available. Otherwise gdb complains that the offsets for the debug info are incorrect and doesn't load the files.
