target/riscv: Initial introduction of the RISC-V target This ports over the RISC-V architecture from Qemu. This is currently a very barebones transition. No code hooking or any fancy stuff. Currently, you can feed it instructions and query the CPU state itself. This also allows choosing whether or not RISC-V 32-bit or RISC-V 64-bit is desirable through Unicorn's interface as well. Extremely basic examples of executing a single instruction have been added to the samples directory to help demonstrate how to use the basic functionality.

target/riscv: Add a base 32 and 64 bit CPU At the same time deprecate the ISA string CPUs. It is dobtful anyone specifies the CPUs, but we are keeping them for the Spike machine (which is about to be depreated) so we may as well just mark them as deprecated. Backports commit 8903bf6e6d73d03b988b4a8197132de2ad681ff5 from qemu

DEFINE_CPU(TYPE_RISCV_CPU_BASE64, riscv_base64_cpu_init),
target/riscv: Initial introduction of the RISC-V target This ports over the RISC-V architecture from Qemu. This is currently a very barebones transition. No code hooking or any fancy stuff. Currently, you can feed it instructions and query the CPU state itself. This also allows choosing whether or not RISC-V 32-bit or RISC-V 64-bit is desirable through Unicorn's interface as well. Extremely basic examples of executing a single instruction have been added to the samples directory to help demonstrate how to use the basic functionality.

target/riscv: Restructure deprecatd CPUs Restructure the deprecated CPUs to make it clear in the code that these are depreated. They are already marked as deprecated in qemu-deprecated.texi. There are no functional changes. Backports commit c1fb65e63cfca4506a14b084afd0eca2dc464fe8 from qemu
