2023-03-05target/riscv: implement Zicbom extensionChristoph Muellner
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.

2023-03-05target/riscv: implement Zicboz extensionChristoph Muellner
The RISC-V base cache management operation (CBO) ISA extension has been ratified. It defines three extensions: Cache-Block Management, Cache-Block Prefetch and Cache-Block Zero. More information about the spec can be found at [1]. Let's start by implementing the Cache-Block Zero extension, Zicboz. It uses the cbo.zero instruction that, as with all CBO instructions that will be added later, needs to be implemented in an overlap group with the LQ instruction due to overlapping patterns. cbo.zero throws a Illegal Instruction/Virtual Instruction exception depending on CSR state. This is also the case for the remaining cbo instructions we're going to add next, so create a check_zicbo_envcfg() that will be used by all Zicbo[mz] instructions.
