Currently, we have fixed TLB flush types supported by the remote TLB library. This approach is not flexible and does not allow custom local TLB flush function. For example, after updating PMP entries on a set of HARTs at runtime, we have to flush TLB on these HARTs as well. To support custom local TLB flush function, we replace the "type" field of "struct sbi_tlb_info" with a local TLB flush function pointer. We also provide definitions of standard TLB flush operations (such as fence_i, sfence.vma, hfence.vvma, hfence.gvma, etc).
