[Qemu-devel] [PATCH v1 0/1] xilinx_spips dummy bytes fix

2018-04-17 Thread Sai Pavan Boddu
For zynq-7000 boards, we saw issues when u-boot/linux accessing the qspi. Issue is due to wrong dummy byte transfers for few of un-handled commands ex: 0x9F, 0x6, 0xe9, 0x4, 0x18, etc There are many unhandled commands which do not require dummy bytes but they can be followed by address cycles.
