Sean Christopherson 1dec2e1f19 i386: Update SGX CPUID info according to hardware/KVM/user input
Expose SGX to the guest if and only if KVM is enabled and supports
virtualization of SGX.  While the majority of ENCLS can be emulated to
some degree, because SGX uses a hardware-based root of trust, the
attestation aspects of SGX cannot be emulated in software, i.e.
ultimately emulation will fail as software cannot generate a valid
quote/report.  The complexity of partially emulating SGX in Qemu far
outweighs the value added, e.g. an SGX specific simulator for userspace
applications can emulate SGX for development and testing purposes.

Note, access to the PROVISIONKEY is not yet advertised to the guest as
KVM blocks access to the PROVISIONKEY by default and requires userspace
to provide additional credentials (via ioctl()) to expose PROVISIONKEY.

Sean Christopherson 80509c5557 i386: Add 'sgx-epc' device to expose EPC sections to guest
SGX EPC is enumerated through CPUID, i.e. EPC "devices" need to be
realized prior to realizing the vCPUs themselves, which occurs long
before generic devices are parsed and realized.  Because of this,
do not allow 'sgx-epc' devices to be instantiated after vCPUS have
been created.

The 'sgx-epc' device is essentially a placholder at this time, it will
be fully implemented in a future patch along with a dedicated command
to create 'sgx-epc' devices.

Philippe Mathieu-Daudé b5b318608e hw/i386: Introduce X86_FW_OVMF Kconfig symbol
Introduce the X86_FW_OVMF Kconfig symbol for OVMF-specific code.
Move the OVMF-specific code from pc_sysfw.c to pc_sysfw_ovmf.c,
adding a pair of stubs.
Update MAINTAINERS to reach OVMF maintainers when these new
files are modified.

This fixes when building the microvm machine standalone:

  /usr/bin/ld: libqemu-i386-softmmu.fa.p/target_i386_monitor.c.o: in
  function `qmp_sev_inject_launch_secret':
  target/i386/monitor.c:749: undefined reference to `pc_system_ovmf_table_find'

Fixes: f522cef9b3 ("sev: update sev-inject-launch-secret to make gpa optional")
