target/riscv: implement Zicbom extension Zicbom is the Cache-Block Management extension defined in the already ratified RISC-V Base Cache Management Operation (CBO) ISA extension [1]. The extension contains three instructions: cbo.clean, cbo.flush and cbo.inval. All of them must be implemented in the same group as LQ and cbo.zero due to overlapping patterns. All these instructions can throw a Illegal Instruction/Virtual Instruction exception, similar to the existing cbo.zero. The same check_zicbo_envcfg() is used to handle these exceptions. Aside from that, these instructions also need to handle page faults and guest page faults. This is done in a new check_zicbom_access() helper. As with Zicboz, the cache block size for Zicbom is also configurable. Note that the spec determines that Zicbo[mp] and Zicboz can have different cache sizes (Section 2.7 of [1]), so we also include a 'cbom_blocksize' to go along with the existing 'cboz_blocksize'. They are set to the same size, so unless users want to play around with the settings both sizes will be the same.

riscv: Add support for the Zfa extension This patch introduces the RISC-V Zfa extension, which introduces additional floating-point instructions: * fli (load-immediate) with pre-defined immediates * fminm/fmaxm (like fmin/fmax but with different NaN behaviour) * fround/froundmx (round to integer) * fcvtmod.w.d (Modular Convert-to-Integer) * fmv* to access high bits of float register bigger than XLEN * Quiet comparison instructions (fleq/fltq) Zfa defines its instructions in combination with the following extensions: * single-precision floating-point (F) * double-precision floating-point (D) * quad-precision floating-point (Q) * half-precision floating-point (Zfh) Since QEMU does not support the RISC-V quad-precision floating-point ISA extension (Q), this patch does not include the instructions that depend on this extension. All other instructions are included in this patch. The Zfa specification can be found here: https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex The Zfa specifciation is frozen and is in public review since May 3, 2023: https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg The patch also includes a TCG test for the fcvtmod.w.d instruction. The test cases test for correct results and flag behaviour. Note, that the Zfa specification requires fcvtmod's flag behaviour to be identical to a fcvt with the same operands (which is also tested).
