Subject: [PATCH v2 0/2] ZynqMP QSPI supports SPI transfer using DMA mode, but currently this
Date: Mon, 8 Feb 2021 13:25:22 +0800 [thread overview]
Message-ID: <1612761924-68000-1-git-send-email-bmeng.cn@gmail.com> (raw)

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()
