15        * startup/sbrk.c: New file.
16        * startup/bspstart.c: This patch implements 'sbrk'
17        for the powerpc-shared BSP to work around what's known as the
18        '32Mb problem' in combination with run-time loaded code.
19        GCC normally generates (PowerPC) code doing 'short jumps' which
20        requires all text segments being in the same 32Mb area of memory.
21        However, some run-time loaders use (e.g. heap-) memory violating the
22        stated limitation on hardware with more than 32Mb of memory.
23        (NOTE: portable loaders are probably not even aware of this
24        GCC/CPU specific problem.)
25
26        This patch implements a simple workaround: At boot time, the system is
27        only provided with 32Mb of memory. The user is supposed to load all
28        necessary modules prior to that limit being exhausted. Once that
29        happens, newlib/malloc end up trying to 'sbrk()' for more memory and
30        the implementation provided by this patch will then make the rest of
31        the physical memory available.

297        Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably
298        with the goal to make it more flexible and reusable by other
299        BSPs. The main strategies were:
300            - eliminate hardcoded base addresses; devices use offsets
301              and a BSP defined base address.
302            - separate functionality into different files (e.g. reboot from
303              inch.c to reboot.c) which can be overridden by a 'derived' BSP.
304            - separate initialization code into separate files (e.g.  PCI
305              bridge detection/initialization was separated from the more
306              generic PCI access routines), also to make it easier for
307              'derived' BSPs to substitute their own initialization code.
308        There are also a couple of enhancements and fixes:
309            - IRQ handling code now has a hook for attaching a VME bridge.
310            - OpenPIC is now explicitely initialized (polarities, senses).
311              Eliminated the implicit assumption on the presence of an ISA PIC.
312            - UART and console driver now supports more than 1 port. The current
313              maximum of 2 can easily be extended by enlarging a table (it
314              would even be easier if the ISR API was not broken by design).
315            - fixed polled_io.c so it correctly supports console on COM2
316            - fixed TLB invalidation code (start.S).
317            - exception handler prints a stack backtrace.
318            - added BSP_pciFindDevice() to scan the pci bus for a particular
319              vendor/device/instance.

326        and direction of segments to memory regions may also have been

401        * start/start.S: Increased BAT0 mapping of RAM from 64 meg to
402        256 meg to allow operation on boards with larger RAM sizes.
403        * vectors/vectors_init.c: Modified to call 'generic' powerpc
404        vector function (mpc60x_vector_is_valid) instead of MPC750
405        specific function to allow operation on boards with CPUs other
406        than the MPC750.

409
410        * Makefile.am, console/consoleIo.h, include/bsp.h:
411        These modifications are part of the conversion of the
412        mpc8xx CPU to the "new exception processing model."
413
4142000-11-01      Joel Sherrill <joel@OARcorp.com>
415
416        * startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
417        and libcsupport.h moved from libc to lib/include/rtems and
418        now must be referenced as <rtems/XXX.h>.   Header file order
419        was cleaned up while doing this.
420
4212000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
422
423        * startup/linkcmds: Added lines so DWARF debug information
424        would be available.  Otherwise gdb complains that the offsets
425        for the debug info are incorrect and doesn't load the files.
426
4272000-09-05      Joel Sherrill <joel@OARcorp.com>
428
429        * start/start.S: Include proper files to compile.
