* ChangeLog, Makefile.am, README, bsp_specs, configure.ac,
preinstall.am, times, console/console.c, include/bsp.h,
include/cplb.h, include/tm27.h, make/custom/TLL6527M.cfg,
startup/bspstart.c, startup/linkcmds: New files.
Initial port for the TLL6527Mboard that contains blackfin 52X
range of processors. Used eZKit533 as a reference for building
the port.
PR 1781/bsps
* bf52x/include: Added additional MMR.
* bf52x/interrupt: The BF52X processors have a different
System interrupt controller than present in the 53X range of
processors. The 52X have 8 interrupt assignment registers. The
implementation uses tables to increase predictability.
* serial/uart.?: Added DMA based and interrupt based transfer
support. The uart code used a single ISR for TX and RX and tried
to identify and multiplex inside the ISR. In the new code the
type of interrupt is identified by the central ISR dispatcher
bf52x/interrupt or interrupt/. This simplifies the UART ISR.
PR 1781/bsps
* console/console-io.c: The UART RX and TX are different ISR
now. So the array containing the registeration changes. The
change is due to change in the libcup uart function.
PR 1768/bsps
* shared/irq/irq_asm.S: The nbench benchmark highlighted the fact that
we do not perform a cld before calling C code in the ISR. This was
historically not a problem but gcc 4.3 changed the behavior. From
http://gcc.gnu.org/gcc-4.3/changes.html
* shared/start/start.S: Default exception handler will result in
bsp_reset().
* shared/startup/linkcmds.base: Move unsupported sections into
read-only section. Changed barrier sections.
PR 1729/cpukit
* Makefile.am, configure.ac: Add next step in SMP support. This adds an
allocated array of the Per_CPU structures to support multiple cpus vs
a single instance of the structure which is still used if SMP support
is disabled. Configuration support is also added to explicitly enable
or disable SMP. But SMP can only be enabled for the CPUs which will
support it initially -- SPARC and i386. With the stub BSP support, a
BSP can be run as a single core SMP system from an RTEMS data
structure standpoint.

* Makefile.am, preinstall.am, console/console.c, console/keyboard.c,
console/keyboard.h, console/pc_keyb.c, console/ps2_mouse.c,
console/vgainit.c: Made mouse parser engine generic. Now use generic
serial mouse driver. Moved many externs from C to .h.
* console/kbd_parser.c, console/serial_mouse_config.c: New files.
* console/mouse_parser.c, console/mouse_parser.h,
console/serial_mouse.c, console/serial_mouse.h: Removed.
PR 1738/bsps
* clock/clock.c, include/bsp.h, network/network.c: system clock driver
programs the PIT w/o assuming the CPU clock frequency being a power
of two.
PR 1748/bsps
* clock/ckinit.c, include/leon.h: When the clock tick generates an
interrupt WHILE we have interrupts disabled doing a get TOD or
uptime, the get nanoseconds handler was returning a bogusly large
number.

PR 1750/bsps
* console/erc32_console.c, make/custom/erc32.cfg: The new console
driver did not support polled mode. It also had a bug in which it
could lose a transmitter interrupt.
