[PATCH v2 0/4] Add PMEM support for RISC-V

[Anup Patel <apatel@ventanamicro.com>]

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_v2 branch at:
https://github.com/avpatel/linux.git

Changes since v1:
 - Fix error reported by test bot
   https://lore.kernel.org/all/202208272028.IwrNZ0Ur-lkp@intel.com/

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
