For a very high speed DMA various periphral devices need
scatter-gather list support. The DMA hardware support link list items.
This list can be circular also (adding new flag DMA_PREP_CIRCULAR_LIST)
Right now this flag is in driver header and should be moved to
dmaengine header file eventuallySigned-off-by: Ramesh Babu K V

This patch add DMA drivers for DMA controllers in Langwell chipset
of Intel(R) Moorestown platform and DMA controllers in Penwell of
Intel(R) Medfield platfromThis patch adds support for Moorestown DMAC1 and DMAC2 controllers.
It also add support for Medfiled GP DMA and DMAC1 controllers.
These controllers supports memory to peripheral and peripheral to
memory transfers. It support only single block transfers.This driver is based on Kernel DMA engine
Anyone who wishes to use this controller should use DMA engine APIsThis controller exposes DMA_SLAVE capabilities and notifies the client drivers
of DMA transaction completionConfig option required to be enabled CONFIG_INTEL_MID_DMAC=y
