Enable support for the QCOM BAM DMA controller. This controller
provides DMA capabilities for a variety of on-chip devices.

Enable support for the Qualcomm Technologies HIDMA Management.
Each DMA device requires one management interface driver
for basic initialization before QCOM_HIDMA channel driver can
start managing the channels. In a virtualized environment,
the guest OS would run QCOM_HIDMA channel driver and the
host would run the QCOM_HIDMA_MGMT management driver.

select DMA_ENGINE
help
Enable support for the Qualcomm Technologies HIDMA controller.
The HIDMA controller supports optimized buffer copies
(user to kernel, kernel to kernel, etc.). It only supports
memcpy interface. The core is not intended for general
purpose slave DMA.
