Subject: [PATCH] soc: fsl: dpio: enable qbman CENA portal memory access
|
|
|
|
Once we enable the cacheable portal memory, we need to do
|
|
cache flush for enqueue, vdq, buffer release, and management
|
|
commands, as well as invalidate and prefetch for the valid bit
|
|
of management command response and next index of dqrr.
