[PATCH v2] arch/ppc/qemu: Clean up and add more cpu infos
by BALATON Zoltan
Removed unused clock_frequency member from struct cpudef which is get from
FW_CFG and added bus-frequency property to complete the frequency
properties. Also added tlb infos to cpudef (with values only for G4
currently as I have no data for other CPUs).

v2: Get bus-frequency from FW_CFG similarly to clock-frequency and
tb-frequency (corresponding patch submitted to QEMU)

[PATCH v3] Updated some device tree properties to match names used by Apple for compatibility with MorphOS
by BALATON Zoltan
The names of some device tree properties are different on old world and
new world Mac hardware and the name of the root node is always
"device-tree" on Apple's OpenFirmware implementation. MorphOS on Apple
hardware expects these names to find these devices.

[PATCH 0/4] Changes for MorphOS
by BALATON Zoltan
Hello,
I'm sending my previous patches split into multiple patches and some more
I've done since. This is not including the change of the / node name as
it was suggested to preserve the original name on some other property but
the name of that new property was not decided so I don't know what to do
with it but that's also needed to get further with MorphOS.
Regards,
BALATON Zoltan

[PATCH] arch/ppc/qemu: Clean up and add more cpu infos
by BALATON Zoltan
Removed unused clock_frequency member from struct cpudef which is get
from FW_CFG and added tlb infos instead (with values only for G4
currently as I have no data for other CPUs). Also added a
bus-frequency property.

How to pass CIF chain arguments on SPARC64?
by Mark Cave-Ayland
Hi all,
I'm working on implementing a version of the CIF chain service for
SPARC64 and am trying to understand what to do with the arguments
parameters. From the specification:
"chain: Frees size bytes of memory starting at virtual address virt,
then executes another client program beginning at address entry. The
argument buffer args, len is copied into the Open Firmware memory and
passed to the other program. The address of the arguments in the Open
Firmware memory is the client program’s second argument, and their
length is its third argument. chain is used to free any remaining memory
for a secondary boot program and begin executing the booted program."
How are the arguments passed to the next client program? A quick peek at
the OpenBOOT source shows that (init-program) only sets up %o4 (CIF) and
%o6 (stack) registers. Does that mean that the arguments should be
copied onto the stack or somehow via the registers? Unfortunately I
can't seem to find a suitable 64-bit SPARC IEEE1275 ISA document anywhere :(
ATB,
Mark.
