-There are various issues regarding this port:
-
-
-
-1) Legal
-
-This port is written by Andrew Bray <andy@i-cubed.co.uk>, and
-is copyright 1995 i-cubed ltd.
-
-This port was later updated by Joel Sherrill <joel@OARcorp.com>
-to test the support for the PPC603, PPC603e, and MPC604.  This
-was tested on the PowerPC simulator PSIM and a VMEbus single board
-computer.
-
-2) CPU support.
-
-This release fully supports the PPC403GA, PPC403GB, PPC603, PPC603e,
-MPC604, MPC750, and numerous MPC8xx processors.  A good faith attempt
-has been made to include support other models based upon available
-documentation including the MPC5xx.  There are two interrupt structures
-supported by the PowerPC port.  The newer structure is supported by
-all the MPC750 and MPC604 BSPs.  This structure is required to use
-the RDBG remote debugging support.
-
-This port was originally written and tested on the PPC403GA (using
-software floating point).  Current ports are tested primarily on
-60x CPUs using the PowerPC simulator PSIM.
-
-Andrew Bray received assistance during the initial porting effort 
-from IBM and Blue Micro and we would like to gratefully acknowledge
-that help.
-
-The support for the PPC602 processor is incomplete as only sketchy
-data is currently available.  Perhaps this model has been dropped.
-
-3) Application Binary Interface
-
-In the context of RTEMS, the ABI is of interest for the following
-aspects:
-
-a)  Register usage.  Which registers are used to provide static variable
-    linkage, stack pointer etc.
-
-b)  Function calling convention.  How parameters are passed, how function
-    variables should be invoked, how values are returned, etc.
-
-c)  Stack frame layout.
-
-I am aware of a number of ABIs for the PowerPC:
-
-a)  The PowerOpen ABI.  This is the original Power ABI used on the RS/6000.
-    This is the only ABI supported by versions of GCC before 2.7.0.
-
-b)  The SVR4 ABI.  This is the ABI defined by SunSoft for the Solaris port
-    to the PowerPC.
-
-c)  The Embedded ABI.  This is an embedded ABI for PowerPC use, which has no
-    operating system interface defined.  It is promoted by SunSoft, Motorola,
-    and Cygnus Support.  Cygnus are porting the GNU toolchain to this ABI.
-
-d)  GCC 2.7.0.  This compiler is partway along the road to supporting the EABI,
-    but is currently halfway in between.
-
-This port was built and tested using the PowerOpen ABI, with the following
-caveat:  we used an ELF assembler and linker.  So some attention may be
-required on the assembler files to get them through a traditional (XCOFF)
-PowerOpen assembler.
-
-This port contains support for the other ABIs, but this may prove to be
-incomplete as it is untested.
-
-The RTEMS PowerPC port supports EABI as the primary ABI.  The powerpc-rtems
-GNU toolset configuration is EABI.
