* hw/dma: Implement a Xilinx CSU DMA modelXuzhou Cheng2021-03-081-0/+52
| | | | | | | | | | | | | | | | | 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. This adds a Xilinx CSU DMA model and the implementation is based on https://github.com/Xilinx/qemu/blob/master/hw/dma/csu_stream_dma.c. The DST part of the model is verified along with ZynqMP GQSPI model. Signed-off-by: Xuzhou Cheng <xuzhou.cheng@windriver.com> Signed-off-by: Bin Meng <bin.meng@windriver.com> Tested-by: Edgar E.

* hw/dma/pl080: Don't use CPU address space for DMA accessesPeter Maydell2018-08-201-0/+5
| | | | | | | | | | | | | | | | | | | Currently our PL080/PL081 model uses a combination of the CPU's address space (via cpu_physical_memory_{read,write}()) and the system address space for performing DMA accesses. For the PL081s in the MPS FPGA images, their DMA accesses must go via Master Security Controllers. Switch the PL080/PL081 model to take a MemoryRegion property which defines its downstream for making DMA accesses. Since the PL08x are only used in two board models, we make provision of the 'downstream' link mandatory and convert both users at once, rather than having it be optional with a default to the system address space.

* dma: xlnx-zynq-devcfg: Fix up XLNX_ZYNQ_DEVCFG_R_MAXNathan Rossi2016-09-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whilst according to the Zynq TRM this device covers a register region of 0x000 - 0x120. The register region is also shared with XADCIF prefix registers at 0x100 and above. Due to how the devcfg and the xadc devices are implemented in QEMU these are separate models with individual mmio regions. As such the region registered by the devcfg overlaps with the xadc when initialized in a machine model (e.g. xilinx-zynq-a9). This patch fixes up the incorrect region size, where XLNX_ZYNQ_DEVCFG_R_MAX is missing its '/ 4' causing it to be 0x460 in size. As well as setting the region size to the 0x0 - 0x100 region so that an xadc device instance can be registered in the correct region to pair with the devcfg device instance.
