Daniel Henrique Barboza cc2bf69a36 target/riscv: add zicbop extension flag ... QEMU already implements zicbom (Cache Block Management Operations) and zicboz (Cache Block Zero Operations). Commit 59cb29d6a5 ("target/riscv: add Zicbop cbo.prefetch{i, r, m} placeholder") added placeholders for what would be the instructions for zicbop (Cache Block Prefetch Operations), which are now no-ops. The RVA22U64 profile mandates zicbop, which means that applications that run with this profile might expect zicbop to be present in the riscv,isa DT and might behave badly if it's absent. Adding zicbop as an extension will make our future RVA22U64 implementation more in line with what userspace expects and, if/when cache block prefetch operations became relevant to QEMU, we already have the extension flag to turn then on/off as needed.
