[PATCH v8 00/18] Add support for FDMA DMA controller and slim core rproc found on STi chipsets
Hi Vinod, Bjorn, Patrice,
This patchset adds support for the Flexible Direct Memory Access (FDMA) core
found on STi chipsets from STMicroelectronics. The FDMA is a slim core CPU
with a dedicated firmware. It is a general purpose DMA controller supporting
16 independent channels and data can be moved from memory to memory or between
memory and paced latency critical real time targets.
