From: "Chuah, Kim Tatt" <kim.tatt.ch...@intel.com> These patches fix a DNV HSUART DMA issue with timeout interrupts which causes: - RX to be padded with zeros up to 4kB when <4kB should be received - RX to be truncated at 4kB when >4kB should be received. These patches have been tested on Intel Denverton platform.
