[PATCH 16/20] kbuild: powerpc: use common install script

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: 2021-04-07 05:35:04

The common scripts/install.sh script will now work for powerpc, all that
is needed is to add it to the list of arches that do not put the version
number in the installed file name.

After the kernel is installed, powerpc also likes to install a few
random files, so provide the ability to do that as well.

With that we can remove the powerpc-only version of the install script.

I want comments from the ppc maintainers
because this code is already broken.


This 'zInstall' target is unreachable.

See commit c913e5f95e546d8d3a9f99ba9908f7e095cbc1fb

It added the new target 'zInstall', but it is not hooked anywhere.
It is completely useless for 6 years, and nobody has pointed it out.
So, I think nobody is caring about this broken code.

One more thing, Kbuild does not recognize it as an installation target
because the 'I' in 'zInstall' is a capital letter.

The name of the installation target must be '*install',
all letters in lower cases.
