[PATCH 0/8] aspeed: I2C fixes, -drive removal (first step)

[Cédric Le Goater]

Hello,

This series starts with a first set of patches fixing I2C slave mode
in the Aspeed I2C controller, a test device and its associated test in
avocado.

Follow some cleanups which allow the use of block devices instead of
drives. So that, instead of specifying :

  -drive file=./flash-ast2600-evb,format=raw,if=mtd
  -drive file=./ast2600-evb.pnor,format=raw,if=mtd
  ...

and guessing from the order which bus the device is attached to, we
can use :

  -blockdev node-name=fmc0,driver=file,filename=./bmc.img
  -device mx66u51235f,bus=ssi.0,drive=fmc0
  -blockdev node-name=fmc1,driver=file,filename=./bmc-alt.img
  -device mx66u51235f,bus=ssi.0,drive=fmc1 
  -blockdev node-name=pnor,driver=file,filename=./pnor
  -device mx66l1g45g,bus=ssi.1,drive=pnor
  ...

It is not perfect, the CS index still depends on the order, but it is
now possible to run a machine without -drive ...,if=mtd.

This lacks the final patch enabling the '-nodefaults' option by not
creating the default devices if specified on the command line. It
needs some more evaluation of the possible undesired effects. 
Thanks,

C.
