Cover from Samuel Ortiz from (part 1) [1]:

  This patchset allows for building and running ARM targets with TCG
  disabled. [...]

  The rationale behind this work comes from the NEMU project where we're
  trying to only support x86 and ARM 64-bit architectures, without
  including the TCG code base. We can only do so if we can build and run
  ARM binaries with TCG disabled.

v3 almost 18 months later:
- Rebased
- Addressed Thomas review comments
- Added Travis-CI job to keep building --disable-tcg on ARM

v2 [2]:
- Addressed review comments from Richard and Thomas from v1 [3]

Regards,

Phil.

"accel: Allow targets to use Kconfig, disable semihosting by default"
https://lists.gnu.org/archive/html/qemu-devel/2020-03/msg04653.html

Philippe Mathieu-Daudé (15):
  target/arm: Rename KVM set_feature() as kvm_set_feature()
  target/arm: Restrict DC-CVAP instruction to TCG accel
  target/arm: Restric the Address Translate operations to TCG accel
  target/arm: Restrict Virtualization Host Extensions instructions to
    TCG
  target/arm: Move Makefile variable restricted to CONFIG_TCG
  target/arm: Add semihosting stub to allow building without TCG
  target/arm: Move ARM_V7M Kconfig from hw/ to target/
  target/arm: Restrict ARMv4 cpus to TCG accel
  target/arm: Restrict ARMv5 cpus to TCG accel
  target/arm: Restrict ARMv6 cpus to TCG accel
  target/arm: Restrict ARMv7 R-profile cpus to TCG accel
  target/arm: Restrict ARMv7 M-profile cpus to TCG accel
  hw/arm: Automatically select the 'virt' machine on KVM
  hw/arm: Do not build to 'virt' machine on Xen
  .travis.yml: Add a KVM-only Aarch64 job

Samuel Ortiz (1):
  target/arm: Do not build TCG objects when TCG is off

Thomas Huth (3):
  target/arm: Make set_feature() available for other files
  target/arm: Make cpu_register() available for other files
  target/arm: Make m_helper.c optional via CONFIG_ARM_V7M
