This first one below looked like it only belonged in a
virtual memory environment. The second one was causing
problems without the PROVIDE() - I don't know why.
Installing of bsp_specs for aliased bsps is broken. Instead of installing
RTEMS_BSP_FAMILY/bsp_specs, RTEMS_BSP/bsp_specs was tried to be installed.
The patch below should fix this problem (tested with mips64orion p4600 and
p4650).
This patch addresses a few minor issues and contains a few (minor)
preparations for automake.
* configure.in: Fix for handing c/src/tests subdirectory handling (FIX)
* aclocal/rtems-top.m4:
+ Add TARGET_SUBDIR and --with-target-subdir (preparation of future
enhancements for cross-compiling)
+ Activate RTEMS_ROOT handling (automake preparation)
* automake/*.am: replace comments "#" with "##" so that comments won't
get included into Makefile.in's anymore
* c/update-tools/* automake support (NEW)
* ./autogen update/enhancement (cf. ./autogen for details)
After applying this patch please run:
./autogen
cvs add c/update-tools/configure.in
cvs add c/update-tools/Makefile.am
cvs add c/update-tools/aclocal.m4

Subject: [Fwd: Goof in SMC initialize for mpc860]
Nick Simon reported this bug in the eth_comm BSP sources. I see that it is
still there in the latest snapshot that Joel sent me (thanks). I thought I
better forward this on to you guys.
Brendan.

In c/src/exec/score/cpu/powerpc/rtems/score/ppc.h:
A lot of hardware interrupts were omitted. Patch enclosed.
I have also added the 821.
In c/src/exec/score/cpu/powerpc/rtems/score/cpu.h:
My patch adds the 821.
In c/src/exec/score/cpu/powerpc/cpu.c:
I have added the MPC821, and also fixed up for the missing hardware
interrupts. It is also inconsistent with
c/src/lib/libcpu/powerpc/mpc860/vectors/vectors.S. This has been fixed.
In c/src/lib/libcpu/powerpc/mpc860/vectors/vectors.S:
Fixed an inconsistency with cpu.c.
I also include some new files to go with the above patches. These are the
cpu library rtems-19990331/c/src/lib/libcpu/powerpc/mpc821/* and
c/src/exec/score/cpu/powerpc/mpc821.h which are minor modifications of
the 860 equivalents.
Other comments:
The various accesses to the DPRAM on the 860 are done with a linktime
symbol. This could be done dynamically at run time by reading the immr
register, and masking off the lower 16 bits. This takes the same amount
of time as loading an address constant, and the same number of
instructions as well (2).
In c/src/lib/libcpu/powerpc/mpc860/console-generic/console-generic.c:
This will silently fail if you attempt to use SCC1. This is only relevant
if you are not using SCC1 for ethernet.
This file also sets one of port B output pins for each port. This is NOT
generic, it should be in the BSP specific console driver.
In your various bsp_specs files, even when ecrti.o is defined as a
startfile, ecrtn.o is not defined as an endfile. Instead it seems to
be in the library list - untidy.
I'd like to make the following change which adds the m360 structure
information to the debugging symbols in the final executable. This
makes it much easier to use the debugger to look at the elements of
the m360 structure.
and Emmanuel Raguet <raguet@crf.canon.fr>. It was submitted in LaTeX
and converted to Texinfo by Joel. At this point, the figures are
largely ignored except to put in an example block to show they are
missing.
The Makefile should be just enough to produce output with no links between
chapters.
