These patches are extracted from a bigger series which - remove generic ISA space, restricting it to the hw that really has it (mostly PCI-ISA bridges) - allow QTest/GDB to use any address space - make I/O address space target-specific (only X86 and AVR have a CPU connected to it) - better handle Harvard architectures
Various patches only make sense if the AVR arch is merged, so instead of waiting and keeping rebasing/testing, let's share what is generic and might be worthwhile. Currently the QMP/QTest commands only use the 1st CPU address space, which has already been reported to limit fuzzing/fault_injection/gdbstub. I'll probably follow with the PCI-ISA bridge part, but let's first see the feedback for this batch. Regards, Phil.
