This directory is for placing custom packages that can be kept separate from
an upstream op-build.  The purpose of this is to make pulling in upstream
op-build updates much easier, since your customizations will not touch any 
files also modified by op-build changes.

openpower/custom/configs        # For machine configs (*_defconfig files)
                /package        # For additional packages.
                /patches        # For patching existing packages.

It is recommended that the layout of the custom/configs and custom/package
directories follow the layout of the openpower/ peers.

The openpower/custom/patches directory should have subdirectories for each
package desired to be patched and patch files contained inside.  For example
to add a patch to skiboot you would create:
    openpower/custom/patches/skiboot/skiboot-0001-example.patch
