This patch series attempts to add emulation support for these two DMAs on the ZynqMP board. The first patch in the series adds a model of the ZynqMP generic DMA (the ZDMA). The second patch in the series connects the two instances of the ZDMA, the GDMA and the ADMA, to the ZynqMP board. Best regards, Francisco Iglesias Changelog: v2 -> v3 * Use sizeof(s->dsc_dst) as the memcpy length when loading dsc_dst. * Remove an unnecessary qemu_log. * Move the setting of DMA_DONE til after the DMA transfer while loop. * Add dsc_src and dsc_dst to vmstate_zdma. v1 -> v2 * Don't unpause the DMA channel if CONT is zero and clear CONT after unpausing. * Added 'state' to the vmstate_zdma. * Renamed defines and variables in 'xlnx-zynqmp: Connect the ZynqMP GDMA and ADMA' to better reflect they are channels variables.
