* shared/vmeUniverse/vmeTsi148.c, shared/vmeUniverse/vmeTsi148.h,
shared/vmeUniverse/vme_am_defs.h: New files.
* Makefile.am, shared/vmeUniverse/README.universe,
shared/vmeUniverse/vmeUniverse.c, shared/vmeUniverse/vmeUniverse.h:
Several VME related upgrades and fixes, hopefully addressing PR#835:
vmeUniverse driver now supports shared interrupts. vmeUniverse now
supports up to four wires between universe and PIC. A new irq mgr
installation routine has been added allowing to use the new features.
(old version is still present for bwd compatibility). Calls have been
added to change interrupt routing (e.g., if wires have different
priorities at the PIC this feature can be used to configure
priorites). Routine for testing VME interrupts has been added (useful
during BSP development). A new header defining standard VME address
modes has been added so that the VME API doesn't have to #include a
particular bridge driver header. For all driver entry points, a 'XX'
variant has been added which allows to pass the chip's base address
[in case a second universe is sitting on a VME card :-)]. Driver now
uses interrupt line as read from PCI config. space (without offset)
BSP needs to use PCI fixup if necessary. Added a driver for the
tundra tsi148 VME bridge.
* shared/vme/README, shared/vme/vme_universe.c: New files.
* Makefile.am, motorola_powerpc/Makefile.am, mvme5500/vme/vmeconfig.c,
shared/vme/VME.h, shared/vme/VMEConfig.h, shared/vme/vmeconfig.c:
Several VME related upgrades and fixes, hopefully addressing PR#835:
Separated API, API-implementation by a specific VME bridge driver and
BSP-specific configuration of the driver into different files,
describing their purpose in a README. All of these changes use the
upgraded vmeUniverse.c driver.
* include/bsp.h, vme/vmeconfig.c: Reverted redefinition of _IO_BASE;
this normally points to ISA space but is misused by this BSP
(inb/outb & friends are all over the place).
* shared/motorola/motorola.c, shared/pci/detect_raven_bridge.c,
shared/pci/pci.c, shared/pci/pci.h, shared/pci/pcifinddevice.c:
Several PCI enhancements and fixes: all BSP flavors now use the
generic clear_hostbridge_errors() routine (this means that only
polling memory probing is possible [see detect_raven_bridge.c for
details]). Interrupt fixup routine now supports multi-function
devices. Interrupt fixup routine now honours a flag/option so that
wrong firmware values can be overridden. Fixed irq routing table for
mvme2100 [PMC]. Added irq routing table for mvme2300. Added a
BSP_pciScan() routine that executes a user callback on each non-empty
slot/fun. Added BSP_pciConfigDump() to display basic config headers.
