[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).

[PATCH v3] Updated some device tree properties to match names used by Apple for compatibility with MorphOS

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.

[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

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.
