[Qemu-devel] [PATCH v6 0/6] Connect the SPI devices to ZynqMP

[Peter Crosthwaite <crosthwaitepeter@gmail.com>]

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
