[PATCH v2 0/2] ZynqMP QSPI supports SPI transfer using DMA mode, but currently this

Posted by Bin Meng 4 years, 9 months ago

From: Bin Meng <bin.meng@windriver.com>

is unimplemented. When QSPI is programmed to use DMA mode, QEMU will
crash. This is observed when testing VxWorks 7.

Add a basic implementation of QSPI DMA functionality.

Changes in v2:
- Remove unconnected TYPE_STREAM_SINK link property
- Add a TYPE_MEMORY_REGION link property, to allow board codes to tell
  the device what its view of the world that it is doing DMA to is
- Replace cpu_physical_memory_write() with address_space_write()

  hw/ssi: xilinx_spips: Clean up coding convention issues
  hw/ssi: xilinx_spips: Implement basic QSPI DMA support
