This patch is a part of the BSP source reorganization.
Update #3285.
|

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart
<Darlene.Stewart@nrc.ca> to add support for a number of very
significant things:
+ BSPs for many variations on the Motorola MBX8xx board series
+ Cache Manager including initial support for m68040
and PowerPC
+ Rework of mpc8xx libcpu code so all mpc8xx CPUs now use
same code base.
+ Rework of eth_comm BSP to utiltize above.
John reports this works on the 821 and 860

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.

both fixed length "raw" names and strings from the API's point of view.
Both inline and macro implementations were tested.
