Patch 1 is the big change, and patches 5 and 6 demo the capability. I have only tested this -S as I do not have images that test SPI handy, but qtree looks correct with the new SPI flashes. V6: Allow use of QOM paths for referencing qbusses Use Alias to implement bus pinout. Regards, Peter Original Cover from Alistair: Connect the SPI devices to Xilinx's ZynqMP. I also need to make some changes to the actual SPI device to imporove the fuctionality, but for the time being this works. V5: - Fix a typo - Use a qdev API to rename the SPI bus V4: - Rebase - Rename the SPI busses so that they can all be accessed from the SoC - Only create one SPI flash device V3: - Don't reach into the SoC to get the SPI Bus V2: - Connect the SPI flash in the board code - Update git patches to properly indicate rename - Add sst25wf080 as a SPI flash Alistair Francis (5): m25p80.c: Add sst25wf080 SPI flash device ssi: Move ssi.h into a separate directory xilinx_spips: Separate the state struct into a header xlnx-zynqmp: Connect the SPI devices xlnx-ep108: Connect the SPI Flash Peter Crosthwaite (1): qdev: get_child_bus(): Use QOM lookup if available hw/arm/pxa2xx.c | 2 +- hw/arm/spitz.c | 2 +- hw/arm/stellaris.c | 2 +- hw/arm/strongarm.c | 2 +- hw/arm/tosa.c | 2 +- hw/arm/xilinx_zynq.c | 2 +- hw/arm/xlnx-ep108.c | 16 +++++++++ hw/arm/xlnx-zynqmp.c | 30 ++++++++++++++++ hw/arm/z2.c | 2 +- hw/block/m25p80.c | 3 +- hw/core/qdev.c | 6 ++++ hw/display/ads7846.c | 2 +- hw/display/ssd0323.c | 2 +- hw/microblaze/petalogix_ml605_mmu.c | 2 +- hw/misc/max111x.c | 2 +- hw/sd/ssi-sd.c | 2 +- hw/ssi/pl022.c | 2 +- hw/ssi/ssi.c | 2 +- hw/ssi/xilinx_spi.c | 2 +- hw/ssi/xilinx_spips.c | 48 +++---------------------- include/hw/arm/xlnx-zynqmp.h | 3 ++ include/hw/{ => ssi}/ssi.h | 10 +++--- include/hw/ssi/xilinx_spips.h | 72 +++++++++++++++++++++++++++++++++++++ 23 files changed, 155 insertions(+), 63 deletions(-) rename include/hw/{ => ssi}/ssi.h (96%) create mode 100644 include/hw/ssi/xilinx_spips.h -- 1.9.1
