Move of_dma_configure() to device.c so that same function can be re-used
for PCI devices to obtain DMA configuration from DT. Also add a second
argument so that for PCI, DT node of root bus host bridge can be used to
obtain the DMA configuration for the slave PCI device.

arm_iommu_create_mapping() has size parameter of size_t and
arm_setup_iommu_dma_ops() can take a value higher than that
when this is called from the of code. So limit the size to

PCI devices on Keystone doesn't have correct dma_pfn_offset set. This patch
add capability to set the dma configuration such as dma-mask, dma_pfn_offset,
and dma ops etc using the information from DT. The prior RFCs and discussions
are available at [1] and [2] below.
[2] : https://www.mail-archive
If there is a DT node available for the root bridge's parent device,
use the dma configuration from that device node. For example, keystone
PCI devices would require dma_pfn_offset to be set correctly in the
device structure of the pci device in order to have the correct dma mask.
The DT node will

This patch adds the support for the APM X-Gene SoC AHBC IOMMU driver.
This driver translates the 32-bit AHB address from the dma master to
42-bit AXI address with the help of a set of AHBC inbound mapper (AIM)
registers. The AHB dma master for slaves, eg: sdhci etc, will use this
driver to do a dma

A still unconfirmed hardware bug prevents the IPMMU microTLB 0 to be
flushed correctly, resulting in memory corruption. DMAC 0 channel 0 is
connected to microTLB 0 on currently supported platforms, so we can't
use it with the IPMMU. As the IOMMU API operates at the device level we

Also arm_iommu_create_mapping() has size parameter of size_t and
arm_setup_iommu_dma_ops() can take a value higher than that. So
limit the size to SIZE_MAX.
