Turn on buffered writes to DRAM. As Device Errata SECF124 notes this may cause
double writes, but that's not really a big problem and benchmarking tests have
shown that buffered writes do gain some performance.

151        rtems_initialize_device_drivers, and
152        rtems_initialize_start_multitasking. This opened the sequence up so
153        that bootcard() could provide a more robust and flexible framework
154        which is easier to explain and understand. This also lays the
155        groundwork for sharing the division of available memory between the
156        RTEMS workspace and heap and the C library initialization across all
157        BSPs.

203        do_zero_of_workspace, extra_mpci_receive_server_stack,
204        stack_allocate_hook, and stack_free_hook. As a side-effect of this
205        effort some multiprocessing code was made conditional and some style
206        clean up occurred.

2542006-12-14      Till Straumann <strauman@slac.stanford.edu>
255
256        * startup/bspstart.c: Changed BSP_installVME_isr() so that
257        the special handling of a 'FPGA interrupt' [this FPGA is *not*
258        present on the uC5282 module but is externally connected to
259        IRQ1 on Eric Norum's particular 'motherboard'] is only
260        activated when connecting to the special vectors > 192.
261        The change allows us ordinary users [:-)] to use IRQ1
262        normally, simply by connecting an ISR to vector 64+1...
263        Also, BSP_enable_irq_at_pic(), BSP_disable_irq_at_pic(),
264        BSP_irq_is_enabled_at_pic() were introduced (compat. with
265        some PPC BSPs).

432
4332005-02-04      Ralf Corsepius <ralf.corsepius@rtems.org>
434
435        * startup/bspstart.c:
436        rtems_interrupt_catch(trampoline, vector, &old_handler).
437
4382005-02-03  Eric Norum <norume@aps.anl.gov>
439
440        * include/bsp.h, startup/bspstart.c: Add 'extended' BSP
441        support (pseudo-VME).
442
4432005-02-02  Eric Norum <norume@aps.anl.gov>
444
445        * network/network.c: Lock FEC/PHYS at 100 Mbs, full-duplex
446
4472005-02-01  Eric Norum <norume@aps.anl.gov>
448
449        * include/bsp.h, network/network.c, startup/bspstart.c: Add some
450          bootprom system calls.
451
4522005-02-01  Eric Norum <norume@aps.anl.gov>
453
454        * start/start.S, network/network.c: Place FEC buffer descriptors
455        in SRAM.  No longer need to worry about buffer descriptor caching.
456
4572005-01-31  Eric Norum <norume@aps.anl.gov>
458
459        * network/network.c, startup/bspstart.c: Processor doesn't snoop
460        FEC DMA so we must invalidate the cache appropriately.

463
464        * .cvsignore: New file.
