target-alpha: Add CLIPPER emulation. This is a DP264 variant, SMP capable, no unusual hardware present. The emulation does not currently include any PCI IOMMU code. Hopefully the generic support for that can be merged to HEAD soon. Signed-off-by: Richard Henderson <rth@twiddle.net>

Clean up header guards that don't match their file name Header guard symbols should match their file name to make guard collisions less likely. Offenders found with scripts/clean-header-guards.pl -vn. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones.

Move target-* CPU file into a target/ folder We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

#include "target/alpha/cpu-qom.h"
hw: include hw header files with full paths Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.

hw: replace hw/i386/pc.h with a header just for the i8259 Remove the need to include i386/pc.h to get to the i8259 functions. This is enough to remove the inclusion of hw/i386/pc.h from all non-x86 files. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

hw/alpha: Provide a PCI-ISA bridge device node - Move initialization of the ISA bus from typhoon_init() to clipper_init(); this apsect of device topology is really associated with the individual model, not the core logic chipset. typhoon_init() now returns the IRQ to use for the output of the ISA PIC. - In clipper_init(), instantiate an i82378 instance, and connect its PIC output to the ISA IRQ input provided by typhoon_init(). Remove the explicit instantiations of i8254 and i82374, as these devices are subsumed by the i82378.

hw/alpha: Set minimum PCI device ID to 1 to match Clipper IRQ mappings Since we are emulating a Clipper device topology, we need to set the minimum PCI device ID to 1, as there is no IRQ mapping for a device at ID 0 (see sys_dp264.c:clipper_map_irq()). - Add a 'devfn_min' argument to typhoon_init(). Pass that argument along to pci_register_root_bus(). - In clipper_init(), pass PCI_DEVFN(1, 0) as the minimum PCI device ID/function.
