Subject: [PATCH 0/5] ocxl: Allow external drivers to access LPC memory

From: Alastair D'Silva <alastair@...ilva.org>

This series provides the prerequisite infrastructure to allow
external drivers to map & access OpenCAPI LPC memory.

Alastair D'Silva (5):
  powerpc: Add OPAL calls for LPC memory alloc/release
  powerpc: Map & release OpenCAPI LPC memory
  ocxl: Tally up the LPC memory on a link & allow it to be mapped
  ocxl: Add functions to map/unmap LPC memory
  ocxl: Provide additional metadata to userspace
