        * include/bsp.h: define CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK

2011-02-11      Ralf Corsépius <ralf.corsepius@rtems.org>

        * irq/discovery_pic.c, network/if_em/rtemscompat_defs.h,
        * network/if_gfe/rtemscompat_defs.h, startup/bspstart.c:
        Use "__asm__" instead of "asm" for improved c99-compliance.

2011-02-02      Ralf Corsépius <ralf.corsepius@rtems.org>

        * configure.ac: Require autoconf-2.68, automake-1.11.1.

2011-01-26      Ralf Corsépius <ralf.corsepius@rtems.org>

        * Makefile.am: Remove build_date.c.
        * startup/bspstart.c: Remove BSP_build_date.

2011-01-26      Ralf Corsépius <ralf.corsepius@rtems.org>

        * network/porting/README, network/porting/if_xxx_rtems.c,
        startup/bspstart.c: Remove CVS artefacts.

2010-09-29      Ralf Corsépius <ralf.corsepius@rtems.org>

        * Makefile.am: Remove -Wno-unused-variable.

2010-08-20      Joel Sherrill <joel.sherrill@oarcorp.com>

        PR 1682/bsps
        * startup/bspstart.c: Add BSP_poll_char.

2010-06-29      Joel Sherrill <joel.sherrill@oarcorp.com>

        * configure.ac: Remove AC_CHECK_SIZEOF([void *]).

2010-06-29      Joel Sherrill <Joel.Sherrill@OARcorp.com>

        * configure.ac: Added AC_CHECK_SIZEOF macro.

2010-05-10      Joel Sherrill <joel.sherrilL@OARcorp.com>

        * include/bsp.h: Do not include <bsp/bsp_bsdnet_attach.h> if networkign
        disabled.

2010-04-14      Ralf Corsépius <ralf.corsepius@rtems.org>

        * network/support/bsp_attach.c: Include <unistd.h>.

2010-03-27      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

        * network/if_gfe/if_gme.c, network/if_em/if_em.c: Removed warnings

2010-02-09  Till Straumann <strauman@slac.stanford.edu>

        * network/if_mve/mv643xx_eth.c: Fixed alignment attribute
        in descriptor declaration. Not the pointers to the descriptors
        have to be aligned but the descriptors themselves (didn't
        cause problems but caused unnecessary holes in 'private' struct).

        FIX: Added more robustness when number of available TX descriptors
        drops to zero. (This can e.g., happen if the link goes bad causing
        packets to stall in the FIFO.) At the following points the transmitter
        is explicitly (re-)started:
          o when link comes up and number of available TXDs is zero the
            TX is restarted.
          o on a failed attempt to send data due to lack of TXDs the
            TX is restarted if swiping the TX ring doesn't yield any
            buffers (i.e., if the # of available buffers is still zero
            after the swipe).

2009-12-14      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * Makefile.am, preinstall.am: Removed ppc_exc_bspsupp.h include file.

2009-12-08      Joel Sherrill <joel.sherrill@oarcorp.com>

        * include/bsp.h: BSP should not define
        CONFIGURE_NUMBER_OF_TERMIOS_PORTS.

2009-12-08      Joel Sherrill <joel.sherrill@oarcorp.com>

        * network/if_em/Makefile, network/if_gfe/Makefile: Removed.

2009-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>

        * Makefile.am, preinstall.am: Account for coverhd.h and tm27.h. Use
        stubs for both.

2009-11-06  Till Straumann <strauman@slac.stanford.edu>

        * Makefile.am, irq/discovery_pic.c, irq/irq_init.c:
        dump raw_exceptions.rel, raw_exception.h; these have
        disappeared. <bsp/vectors.h> must now be included 
        instead.

        * Makefile.am: Add 'altivec.rel'.

        * make/custom/beatnik.cfg: Use -mcpu=7400; this enables
        AltiVec!

2009-11-06  Till Straumann <strauman@slac.stanford.edu>

        * beatnik.cfg, make/custom/beatnik.cfg: moved beatnik.cfg
        to new make/custom subdir.

2009-10-20  Till Straumann <strauman@slac.stanford.edu>

        * startup/bspstart.c: leave 'work-space start' and initial
        stack alone. These are now handled by the shared framework
        and linker script etc. Locate interrupt stack after __rtems_end
        and obtain its size from the configuration.

2009-10-20  Till Straumann <strauman@slac.stanford.edu>

        * network/if_mve/mv643xx_eth.c: made mutex a binary semphore;
        simple binary semaphore doesn't support priority inheritance.
        This was silently ignored under previous releases but is an
        error under 4.10.

2009-10-20  Till Straumann <strauman@slac.stanford.edu>

        * Makefile.am, bsp_specs, preinstall.am, flash/flashcfg.c,
        include/bspopts.h.in, irq/discovery_pic.c, irq/irq_init.c,
        marvell/gt_timer.c, marvell/gt_timer.h, marvel/gti2c.c,
        network/if_gfe/if_gfe.c, network/if_gfe/if_gfe_rtems.c,
        network/if_mve/mv643xx_eth.c, network/support/bsp_attach.c,
        pci/gt_pci_init.c, pci/motload_fixup.c, startup/bspstart.c,
        startup/i2c_init.c:
        Ported to rtems HEAD (to become rtems-4.10). This consisted
        mainly of fixing compiler warnings (mostly: adding prototypes
        to function declarations and moving extern declarations to
        global scope).

        A pecularity: if_gfe.c had to remove 'queue.h' inclusion.
        we have two versions of queue.h: one in newlib another one in 
        rtems - don't know how this is supposed to work...      

2009-10-17  Till Straumann <strauman@slac.stanford.edu>

        * Makefile.am, network/if_mve_mv643xx_eth.c,
        network/if_mve_pub.h: Enhanced low-level API allowing
        the user to selectively enable/disable/acknowledge
        interrupts and to install their own ISR (rather than having
        the driver posting an event to a single task).

2009-10-03  Till Straumann <strauman@slac.stanford.edu>
        * network/if_mve/mv643xx_eth.c:
        BUGFIX: mbuf leak; consume_rx_mbuf() must release mbuf
        if 'len'<=0.

        BUGFIX: Must initialize 'media-word' argument before
        calling BSP_mve_media_ioctl() (defines PHY instance).

2009-06-05  Till Straumann <strauman@slac.stanford.edu>
        * network/if_mve/mv643xx_eth.c, network/if_mve/if_mve_pub.h,
        Makefile.am: Added MC address reference count and
        BSP_mve_mcast_filter_accept_del() to remove a single
        entry from the filter.

2009-06-05  Till Straumann <strauman@slac.stanford.edu>
        * network/if_mve/mv643xx_eth.c, network/if_mve/if_mve_pub.h,
        Makefile.am: first stab at adding multicast support.

2009-06-05  Till Straumann <strauman@slac.stanford.edu>
        * network/if_gfe/if_gfe.c:
        o propagate PROMISC flag to hardware (SIOCSIFFLAGS)
        o handle case where IFF_PROMISC is set (and wasn't before)
          in gfe_hash_fill() routine.

2009-06-02  Till Straumann <strauman@slac.stanford.edu>
        * network/if_gfe/if_gfe.c: activated and fixed multicast
        support.

2009-06-01  Till Straumann <strauman@slac.stanford.edu>
        * network/if_em/if_em.c: activated multicast support.

2008-10-30      Till Straumann <strauman@slac.stanford.edu>

    MERGED from rtems-4-7-branch:
        * Makefile.am, network/if_mve/mv643xx.c, network/if_mve/if_mve_pub.h:
        o Exported new low-level driver entry points:
            - BSP_mve_ack_link_chg() so that changes in PHY link status can be
            propagated to the serial port when handling link-change interrupts.
            - BSP_mve_dump_stats() for printing statistics.
        o FIXED reading of statistics counters.
        o Count interrupts (statistics) in ISR rather than network daemon
          (which is only used by the BSD driver).

2008-10-04      Till Straumann <strauman@slac.stanford.edu>

        * beatnik.cfg: updated to 4.9; removed make-exe
        make-cxx-exe commands. Replaced CPU cflags to use
        -mpowerpc -D__ppc_generic.

2008-10-04      Till Straumann <strauman@slac.stanford.edu>

        * startup/linkcmds: increased size of CODE memory
        area to 32M.

2008-05-10      Till Straumann <strauman@slac.stanford.edu>

        * pci/gt_pci_init.c, pci/pci_io_remap.c: fixed 32-bit
        types. RTEMS' pci_config access functions now use uint32_t,
        earlier versions used unsigned. Both are incompatible,
        unfortunately (gcc regards unsigned and unsigned long different
        beasts leading to warnings and alias-issues :-()

2008-05-10      Till Straumann <strauman@slac.stanford.edu>

        * network/porting/rtemscompat1.h, network/porting/rtemscompat.h,
        network/porting/if_xxx_rtems.c, network/if_gfe/if_gfe_rtems.c:
        Fixed 32-bit types (pci config access, byteorder macros differ
        depending on RTEMS version :-(). We now check for version and
        use appropriate types (unsigned vs. uint32_t).
        Silenced more warnings (ifndef DEBUG_MODULAR the METHODSPTR
        is always non-zero; hence I ifdef'ed the affected code snippet).
        
2008-03-20      Till Straumann <strauman@slac.stanford.edu>

        * include/bsp.h, startup/bspstart.c: confdefs.h now wants
        us to use BSP_INTERRUPT_STACK_SIZE instead of
        CONFIGURE_INTERRUPT_STACK_MEMORY.

2008-03-19      Till Straumann <strauman@slac.stanford.edu>

        * irq/discovery_pic.c: must spare GPP7_0 etc. summary
        interrupts in BSP_enable_irq_at_pic() etc.
        New 'new-exceptions/bspsupport' code scans all IRQS
        and enables or disables depending on the initial config
        having a handler connected. This initial disable operation
        switched-off the summaries and I had no GPP interrupts...

2008-01-04      Till Straumann <strauman@slac.stanford.edu>

        * startup/bspstart.c: changed Kate's copyright note
        again as requested by her email 1/04/2008.

2008-01-04      Till Straumann <strauman@slac.stanford.edu>

        * startup/bspstart.c: changed Kate's copyright note
        as requested by her email 8/16/2007.

2007-12-11      Till Straumann <strauman@slac.stanford.edu>

        * irq/discovery_pic.c: don't print warnings if an
        invalid irq number is passed to BSP_disable_irq_at_pic(),
        BSP_enable_irq_at_pic(). irq_supp.h says we must
        silently ignore.

2007-12-11      Till Straumann <strauman@slac.stanford.edu>

        * Makefile.am: use new irq_bspsupport.rel which was
        split out of exc_bspsupport.rel to provide finer-grained
        control over what BSPs want to use.

2007-12-10      Till Straumann <strauman@slac.stanford.edu>

        * Makefile.am, startup/vpd.c, startup/vpd.h:
        moved VPD support to ../shared/motorola.

2007-12-08      Till Straumann <strauman@slac.stanford.edu>

        * Makefile.am: merged shared/vme/vme_universe.c and
        shared/vme/vme_universe_dma.c into one file.
        Use vme_universe.c, vmeconfig.c from shared area.

2007-11-30      Till Straumann <strauman@slac.stanford.edu>

        * startup/bspstart: removed _Cpu_table.exceptions_in_RAM.

2007/11/27 (TS):
 - Generalized flash support and moved to shared area (libchip would probably
   more appropriate).
2007/10/22 (TS):
 - DECREMENTER interrupt is now handled the same way external interrupts are.
   It can also be assigned a priority and the handler is executed in priority
   order, i.e., it can be preempted by higher-priority interrupts and
   is protected from being preempted by lower-priority irqs.
2007/10/08 (TS):
 - ChangeLog added
 - (Makefile.am) MUST NOT use -msoft-float because this also prevents CR7
   to be set/cleared when calling vararg routines (which may then save/restore
   FP args on the stack or do other bad things) :-(
   Still don't know how to deal with implicit usage of the FPU by GCC
   (problem in ISRs and integer-only tasks).
