The Linux NVDIMM PEM drivers require arch support to map and access the persistent memory device. This series adds RISC-V PMEM support using recently added Svpbmt and Zicbom support.
These patches can also be found in riscv_pmem_v1 branch at: https://github.com/avpatel/linux.git
Anup Patel (4): RISC-V: Fix ioremap_cache() and ioremap_wc() for systems with Svpbmt RISC-V: Move riscv_init_cbom_blocksize() to cacheflush.c RISC-V: Implement arch specific PMEM APIs RISC-V: Enable PMEM drivers
