Subject: [PATCH 0/4] Add PMEM support for RISC-V

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
