In preparation for supporting TCG disablement on ARM, we move most
of TCG related v7m/v8m helpers and APIs into their own file.

Backports commit 7aab5a8c8bb525ea390b4ebc17ab82c0835cfdb6 from qemu
These routines are TCG specific.
The arm_deliver_fault() function is only used within the new
helper. Make it static.
Backports commit e21b551cb652663f2f2405a64d63ef6b4a1042b7 from qemu
Group ARM objects together, TCG related ones at the bottom.
This will help when restricting TCG-only objects.
Backports commit 07774d584267488c8c2f104ae5b552791961908a from qemu
Group Aarch64 rules together, TCG related ones at the bottom.
This will help when restricting TCG-only objects.
Backports commit 87f4f183484dba7a460c59e99dac0dbb9f42ed87 from qemu
Add the infrastructure for building and invoking a decodetree decoder
for the AArch32 VFP encodings. At the moment the new decoder covers
nothing, so we always fall back to the existing hand-written decode.
We need to have one decoder for the unconditional insns and one for
the conditional insns, as otherwise the patterns for conditional
insns would incorrectly match against the unconditional ones too.
Since translate.c is over 14,000 lines long and we're going to be
touching pretty much every line of the VFP code as part of the
decodetree conversion, we create a new translate-vfp.inc.c to hold
the code which deals with VFP in the new scheme. It should be
possible to convert this into a standalone translation unit
eventually, but the conversion process will be much simpler if we
simply #include it midway through translate.c to start with.
Backports commit 78e138bc1f672c145ef6ace74617db00eebaa2ba from qemu
Move all of the fp helpers out of helper.c into a new file.
This is code movement only. Since helper.c has no copyright
header, take the one from cpu.h for the new file.
Backports commit 37356079fcdb34e13abbed8ea0c00ca880c31247 from qemu
The cryptographic internals are stubbed out for now,
but the enable and trap bits are checked.
Backports commit 0d43e1a2d29a05f7b0d5629caaff18733cbdf3bb from qemu
Including only 4, as-yet unimplemented, instruction patterns
so that the whole thing compiles.
Backports commit 38388f7ee3adc04a7e7246c04352451c4f8d00fb from qemu
Split ARM on/off function from PSCI support code.
This will allow to reuse these functions in other code.
Backports commit 825482adde1f971cbddf27e15fb4453ab3fae994 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.
