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
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 98670d47cd8d63a529ff230fd39ddaa186156f8c from qemu
This code is preventing the MMU debug code from displaying virtual
mappings of IO devices (anything that is not located in the RAM).
Before this patch, Qemu would output 0xffffffffffffffff (-1) as the
physical address corresponding to an IO device virtual address.
With this patch the intended physical address is displayed.
Backports commit 7e450a8f50ac12fc8f69b6ce555254c84efcf407 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.
