Hi All,
This is a modification of Alistair's ZynqMP SPI work, which proposes a
solution to the SoC bus-aliasing problem. 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

qdev: get_child_bus(): Use QOM lookup if available
