[PATCH v4] powerpc/defconfig: new way of writing defconfig

Lijun Pan Lijun.Pan at freescale.com
Sat Jun 13 12:52:12 AEST 2015 

It is always a headache dealing with different defconfigs
though they only differ in a few places. Hence we are proposing a new
way of writing the defconfig:
1. Define a basic defconfig say mpc85xx_basic_defconfig
2. Spin off as much features as possible from the current mpc85xx_defconfig
	and create a separate config file, say, smp.config, kvm_500.config
Every time we add a new feature, we don't need to change several
defconfigs, we just add a new *.config
And you could merge any fragments you want into .config with the
current kconfig in Kernel.

With the new rules added into arch/powerpc/Makefile,
you can make it like before, e.g.
make mpc85xx_smp_defconfig

In order to keep the final .config the same as before,
we must first merge all the fragments (without make) repeatedly,
and at last do "make" only once.

The make steps below will generate a different .config as above.
We should not take the following steps.
e.g.
make mpc85xx_basic_defconfig
make smp.config
make kvm_guest.config

v4 changes:
 1. removed many fragments according to the review feedback in v3
 2. I cannot reuse the code in http://patchwork.ozlabs.org/patch/476345/ 
    since I have multiple fragments to merge while the that patch only
    has one fragment.

v3 changes:
