Subject[PATCH 0/3] Add support to handle prefetchable memory
Date
This patch series adds support for configuring the DesignWare IP's ATU
region for prefetchable memory translations.
It first starts by flagging a warning if the size of non-prefetchable
aperture goes beyond 32-bit as PCIe spec doesn't allow it.
And then adds required support for programming the ATU to handle higher
(i.e. >4GB) sizes and then finally adds support for differentiating
between prefetchable and non-prefetchable regions and configuring one of
the ATU regions for prefetchable memory translations purpose.

Vidya Sagar (3):
PCI: of: Warn if non-prefetchable memory aperture size is > 32-bit
PCI: dwc: Add support to program ATU for >4GB memory aperture sizes
PCI: dwc: Add support to handle prefetchable memory mapping
