This patch series adds support for QBMan memory backed portals which is avaialble in devices containing QBMan verion 5.0 and above (for example NXP's LX2160A SoC).
Memory backed portals can be mapped as normal cacheable/shareable memory which allows the portals to migrate between cores without needing manual cache manipulations by the CPU. The patches add support for the new portal attributes in the fsl-mc bus drivers as well as modifying the QBMan driver to use the new portal read trigger mechanism.
