[Qemu-devel] [PATCH v2 0/1] xilinx_spips dummy bytes fix

[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.

To fix this issue for above commands, the next upcoming tx bytes are not 
considered dummies rather sent to slave directly.

Changes for V2:
        Fixed commit message
        Reordered to code, to avoid code duplication.
