Peter Maydell	468e2849cd	target/arm: Implement DBGVCR32_EL2 system register ... The DBGVCR_EL2 system register is needed to run a 32-bit EL1 guest under a Linux EL2 64-bit hypervisor. Its only purpose is to provide AArch64 with access to the state of the DBGVCR AArch32 register. Since we only have a dummy DBGVCR, implement a corresponding dummy DBGVCR32_EL2.

Peter Maydell	0db334c0e4	target/arm: Handle VIRQ and VFIQ in arm_cpu_do_interrupt_aarch32() ... To run a VM in 32-bit EL1 our AArch32 interrupt handling code needs to be able to cope with VIRQ and VFIQ exceptions. These behave like IRQ and FIQ except that we don't need to try to route them to Monitor mode. Backports commit 87a4b270348c69a446ebcddc039bfae31b1675cb from qemu	2018-03-01 22:59:08 -05:00
Thomas Huth	b2f1326437	Move target-* CPU file into a target/ folder ... 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.
