This bit configures endianness of PCI MMIO devices. It is used by
Solaris and OpenBSD sunhme drivers.
Tested working on OpenBSD.
Unfortunately Solaris 10 had a unrelated keyboard issue blocking
testing... another inch towards Solaris 10 on SPARC64 =)
Backports commit ccdb4c5535f41ee4da2ef158f58fca0327e50dab from qemu
Switch the SPARC target from the old unassigned_access hook to the
new do_transaction_failed hook.
This will cause the "if transaction failed" code paths added in
the previous commits to become active if the access is to an
unassigned address. In particular we'll now handle bus errors
during page table walks correctly (generating a translation
error with the right kind of fault status).

This patch moves the define of target access alignment earlier from
target/foo/cpu.h to configure.
Suggested in Richard Henderson's reply to "[PATCH 1/4] tcg: TCGMemOp is now
accelerator independent MemOp"

Nothing in there so far, but all of the plumbing done
within the target ArchCPU state.
Backports commit 5b146dc716cfd247f99556c04e6e46fbd67565a0 from qemu
Now that we have ArchCPU, we can define this generically,
in the one place that needs it.
Backports commit 677c4d69ac21961e76a386f9bfc892a44923acc0 from qemu
Cleanup in the boilerplate that each target must define.
Replace sparc_env_get_cpu with env_archcpu. The combination
CPU(sparc_env_get_cpu) should have used ENV_GET_CPU to begin;
use env_cpu now.
Backports commit 5a59fbce9141c40db0f0a5a6e17583ad9189b48b from qemu
Now that we have both ArchCPU and CPUArchState, we can define
this generically instead of via macro in each target's cpu.h.
Backports commit 29a0af618ddd21f55df5753c3e16b0625f534b3c from qemu
For all targets, into this new file move TARGET_LONG_BITS,
TARGET_PAGE_BITS, TARGET_PHYS_ADDR_SPACE_BITS,
TARGET_VIRT_ADDR_SPACE_BITS, and NB_MMU_MODES.
Include this new file from exec/cpu-defs.h.
This now removes the somewhat odd requirement that target/arch/cpu.h
defines TARGET_LONG_BITS before including exec/cpu-defs.h, so push the
bulk of the includes within target/arch/cpu.h to the top.
Backports commit 74433bf083b0766aba81534f92de13194f23ff3e from qemu
cpu_init(cpu_model) were replaced by cpu_create(cpu_type) so
no users are left, remove it.

it will be used for providing to cpu name resolving class for
parsing cpu model for system and user emulation code.
Along with change add target to null-machine tests, so
that when switch to CPU_RESOLVING_TYPE happens,
it would ensure that null-machine usecase still works.

This function needs to be converted to QOM hook and virtualised for
multi-arch. This rename interferes, as cpu-qom will not have access
to the renaming causing name divergence. This rename doesn't really do
anything anyway so just delete it.
Backports commit 8642c1b81e0418df066a7960a7426d85a923a253 from qemu
As cpu.h is another typically widely included file which doesn't need
full access to the softfloat API we can remove the includes from here
as well. Where they do need types it's typically for float_status and
the rounding modes so we move that to softfloat-types.h as well.
As a result of not having softfloat in every cpu.h call we now need to
add it to various helpers that do need the full softfloat.h
definitions.
Backports commit 24f91e81b65fcdd0552d1f0fcb0ea7cfe3829c19 from qemu
Make CPUSPARCState::def embedded so it would be allocated as part
of cpu instance and we won't have to worry about cleaning def pointer
up mannualy on cpu destruction.
Backports commit 576e1c4c239621482474ba7b495a41bab2d16ae5 from qemu
The MC68040 MMU provides the size of the access that
triggers the page fault.
This size is set in the Special Status Word which
is written in the stack frame of the access fault
exception.
So we need the size in m68k_cpu_unassigned_access() and
m68k_cpu_handle_mmu_fault().
To be able to do that, this patch modifies the prototype of
handle_mmu_fault handler, tlb_fill() and probe_write().
do_unassigned_access() already includes a size parameter.
This patch also updates handle_mmu_fault handlers and
tlb_fill() of all targets (only parameter, no code change).

Backports commit 9d81b2d2000f41be55a0624a26873f993fb6e928 from qemu
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.
