[ Upstream commit ab09da75700e9d25c7dfbc7f7934920beb5e39b9 ]

Building the kernel with O= is affected by stale in-tree build artifacts.

So, if the source tree is not clean, Kbuild displays the following:

  $ make ARCH=um O=build defconfig
  make[1]: Entering directory '/.../linux/build'
  ***
  *** The source tree is not clean, please run 'make ARCH=um mrproper'
  *** in /.../linux
  ***
  make[2]: *** [/.../linux/Makefile:673: outputmakefile] Error 1
  make[1]: *** [/.../linux/Makefile:248: __sub-make] Error 2
  make[1]: Leaving directory '/.../linux/build'
  make: *** [Makefile:248: __sub-make] Error 2

Usually, running 'make mrproper' is sufficient for cleaning the source
tree for out-of-tree builds.

However, building UML generates build artifacts not only in arch/um/,
but also in the SUBARCH directory (i.e., arch/x86/). If in-tree stale
files remain under arch/x86/, Kbuild will reuse them instead of creating
new ones under the specified build directory.

This commit makes 'make ARCH=um clean' recurse into the SUBARCH directory.

Since "serdes0" and "serdes1" which are the sub-nodes of "serdes_wiz0" and "serdes_wiz1" respectively, have been disabled in the SoC file already, and, given that these sub-nodes will only be enabled in a board file if the board utilizes any of the SERDES instances and the peripherals bound to them, we end up in a situation where the board file doesn't explicitly disable "serdes_wiz0" and "serdes_wiz1". As a consequence of this, the following errors show up when booting Linux: wiz bus@f0000:phy@f000000: probe with driver wiz failed with error -12 ... wiz bus@f0000:phy@f010000: probe with driver wiz failed with error -12 To not only fix the above, but also, in order to follow the convention of disabling device-tree nodes in the SoC file and enabling them in the board files for those boards which require them, disable "serdes_wiz0" and "serdes_wiz1" device-tree nodes.
