Modularize the Open Firmware client interface to allow run-time switching of OFW access semantics, in order to allow future support for real-mode OF access and flattened device frees. OF client interface modules are implemented using KOBJ, in a similar way to the PPC PMAP modules. Because we need Open Firmware to be available before mutexes can be used on sparc64, changes are also included to allow KOBJ to be used very early in the boot process by only using the mutex once we know it has been initialized.

Factor out platform dependent things unrelated to device drivers into a new platform module. These are probed in early boot, and have the responsibility of determining the layout of physical memory, determining the CPU timebase frequency, and handling the zoo of SMP mechanisms found on PowerPC.

o Move the prototype of mem_valid() from ofw_machdep.h to md_var.h. This avoids that mem.c has to include ofw_machdep.h, including all OFW related headers. o Provide a stub for OF_decode_addr(), which is used by low-level console drivers to obtain a tag and handle given a OFW phandle. This is different from sparc64, where a fake bus tag needs to be created explicitly.

Rearchitect platform memory map parsing to make it less Open Firmware-centric: - Keep the static list of regions in platform.c instead of ofw_machdep.c - Move various merging and sorting operations to platform.c as well - Move apple_hacks code out of ofw_machdep.c and into platform_powermac.c, where it belongs - Move CHRP-specific dynamic-reconfiguration memory parsing into platform_chrp.c instead of pretending it is shared code

void ofw_mem_regions(struct mem_region *, int *, struct mem_region *, int *);
Rework handling of ofw_quiesce(), making it the responsibility of the platform modules. Whether to call this function or not is highly machine dependent: on some systems, it is required, while on others it breaks everything. Platform modules are in a better position to figure this out. This is required for POWER hypervisor SCSI to work correctly. There are no functional changes on Powermac systems. Approved by: re (kib)

void ofw_quiesce(void); /* Must be called before VM is up! */
Save and restore the trap vectors when doing OF calls on pSeries machines. It turned out that on pSeries machines the call into OF modified the trap vectors and this made further behaviour unpredictable. With this commit I'm now able to boot multi user on a network booted environment on my IntelliStation 285. This is a POWER5+ machine. Discussed with: nwhitehorn MFC after: 1 week
