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

259 | Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably |
---|
260 | with the goal to make it more flexible and reusable by other |
---|
261 | BSPs. The main strategies were: |
---|
262 | - eliminate hardcoded base addresses; devices use offsets |
---|
263 | and a BSP defined base address. |
---|
264 | - separate functionality into different files (e.g. reboot from |
---|
265 | inch.c to reboot.c) which can be overridden by a 'derived' BSP. |
---|
266 | - separate initialization code into separate files (e.g. PCI |
---|
267 | bridge detection/initialization was separated from the more |
---|
268 | generic PCI access routines), also to make it easier for |
---|
269 | 'derived' BSPs to substitute their own initialization code. |
---|
270 | There are also a couple of enhancements and fixes: |
---|
271 | - IRQ handling code now has a hook for attaching a VME bridge. |
---|
272 | - OpenPIC is now explicitely initialized (polarities, senses). |
---|
273 | Eliminated the implicit assumption on the presence of an ISA PIC. |
---|
274 | - UART and console driver now supports more than 1 port. The current |
---|
275 | maximum of 2 can easily be extended by enlarging a table (it |
---|
276 | would even be easier if the ISR API was not broken by design). |
---|
277 | - fixed polled_io.c so it correctly supports console on COM2 |
---|
278 | - fixed TLB invalidation code (start.S). |
---|
279 | - exception handler prints a stack backtrace. |
---|
280 | - added BSP_pciFindDevice() to scan the pci bus for a particular |
---|
281 | vendor/device/instance. |

362 | |

363 | * start/start.S: Increased BAT0 mapping of RAM from 64 meg to |
---|
364 | 256 meg to allow operation on boards with larger RAM sizes. |
---|
365 | * vectors/vectors_init.c: Modified to call 'generic' powerpc |
---|
366 | vector function (mpc60x_vector_is_valid) instead of MPC750 |
---|
367 | specific function to allow operation on boards with CPUs other |
---|
368 | than the MPC750. |

---|
371 | |
---|
372 | * Makefile.am, console/consoleIo.h, include/bsp.h: |

---|
377 | |
---|
378 | * startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h, |
---|
379 | and libcsupport.h moved from libc to lib/include/rtems and |
---|
380 | now must be referenced as <rtems/XXX.h>. Header file order |
---|
381 | was cleaned up while doing this. |

383 | 2000-09-29 Charles-Antoine Gauthier <charles.gauthier@nrc.ca> |
---|
384 | |
---|
385 | * startup/linkcmds: Added lines so DWARF debug information |
---|
386 | would be available. Otherwise gdb complains that the offsets |
---|
387 | for the debug info are incorrect and doesn't load the files. |
---|
388 | |
---|
389 | 2000-09-05 Joel Sherrill <joel@OARcorp.com> |
