RTEMS (Real-Time Executive for Multiprocessor Systems) is a free open source real-time operating sys

2001-05-15	Till Straumann <[e-mail]>

	* mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: New files. Missed in
	merge of PR213.

2001-05-14	Joel Sherrill <[e-mail]>

	* shared/include/cpuIdent.c: Account for duplicate numbers.

2002-05-01	Ralf Corsepius <[e-mail]>

	* rtems/powerpc/debugmod.h: New file (extracted from
	score/ppc.h).
	* Makefile.am: Relect changes above.

2001-05-14	Till Straumann <[e-mail]>

	* shared/include/io.h: Per PR215 address the following issues:
	    - _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET
	      are no longer defined by libcpu (powerpc/shared/include/io.h)
	      but by the BSP (who is the only one to know the values)
	    - the affected BSP (shared/motorola) headers have been fixed
	      in a separate "libbsp/powerpc/shared" patch.
	    - the DEC 21140 driver (libchip/network/dec21140.c) has been
	      fixed to use PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET.
	      and PCI_MEM_BASE instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE
	      is to be defined by the BSP who is using this driver.
	    - the DEC driver also has been fixed to use the newer
	      rtems_bsp_delay_in_bus_cycles() instead of the obsolete
	      delay_in_bus_cycles().

2001-05-14	Till Straumann <[e-mail]>

	* rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add 
	the following:
	    - support for the MPC74000 (AKA G4); there is no
	      AltiVec support yet, however.
	    - the cache flushing assembly code uses hardware-flush on the G4.
	      Also, a couple of hardcoded numerical values were replaced
	      by more readable symbolic constants.
	    - extended interrupt-disabled code section so enclose the entire
	      cache flush/invalidate procedure (as recommended by the book).
	      This is not (latency) critical as it is only used by
	      init code but prevents possible corruption.
	    - Trivial page table support as been added.
	      (1:1 effective-virtual-physical address mapping which is only
	      useful only on CPUs which feature hardware TLB replacement,
	      e.g. >604.  This allows for write-protecting memory regions,
	      e.g. text/ro-data which makes catching corruptors a lot easier.
	      It also frees one DBAT/IBAT and gives more flexibility
	      for setting up address maps :-)
	    - setdbat() allows changing BAT0 also (since the BSP may use
	      a page table, BAT0 could be available...).
	    - asm_setdbatX() violated the SVR ABI by using
	      r20 as a scratch register; changed for r0
	    - according to the book, a context synchronizing instruction is
	      necessary prior to and after changing a DBAT -> isync added

2001-04-03	Joel Sherrill <[e-mail]>

	or not at its discretion.

	default definition for the macros
	rtems_cpu_configuration_get_timer_least_valid and

	Remove mpc604 from new_exception_processing.

2001-11-21	Ralf Corsepius <[e-mail]>

	* configure.ac: Remove ppc603e from old_exception_processing.

	* ChangeLog: Corrected spacing.

2001-11-14	Till Straumann <[e-mail]>

	* new_exception_processing/cpu_asm.S: Support double or single
	precision context switches.  Note that doing a single precision
	context save/restore on a double precision PowerPC machine does not
	only result in rounding errors but also screws up the FPSCR register!

2001-11-08	Dennis Ehlin (ECS) <[e-mail]>

	This modification is part of the submitted modifications necessary to
	support the IBM PPC405 family.  This submission was reviewed by
	Thomas Doerfler <[e-mail]> who ensured it did
	not negatively impact the ppc403 BSPs.  The submission and tracking
	process was captured as PR50.
	* ppc403/console/console405.c ppc403/tty_drv/.cvsignore,
	ppc403/tty_drv/Makefile.am, ppc403/tty_drv/tty_drv.c,
	ppc403/tty_drv/tty_drv.h: New files.
	* Makefile.am, README, configure.ac, old_exception_processing/cpu.c,
	old_exception_processing/cpu.h, ppc403/Makefile.am,

	ppc403/console/console.c, ppc403/ictrl/ictrl.c, ppc403/ictrl/ictrl.h,
	ppc403/timer/timer.c: Modified.

2001-11-07	Joel Sherrill <[e-mail]>

	* configure.ac: Delete the commented out line that said that
	the mpc8260 used the old exception processing model.  This line
