Subject: [PATCH 0/2] hw/ssi: xilinx_spips: Implement basic QSPI DMA support
Date: Sat, 6 Feb 2021 22:38:12 +0800 [thread overview]
Message-ID: <1612622294-37297-1-git-send-email-bmeng.cn@gmail.com> (raw)
From: Bin Meng <bin.meng@windriver.com>
ZynqMP QSPI supports SPI transfer using DMA mode, but currently this
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.
