Subject: [PATCH 0/7] Add support for FDMA DMA controller found on STi chipsets

Hi,

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.

To increase the number of peripheral request, support is also added for the
FDMA crossbar hardware, which can be used to multiplex up to 96 peripheral
requests, to the 3 fdma engines.

regards,

Peter.
