Two config options exist to define powerpc MPC8xx:

In addition, CONFIG_PPC_8xx also defines CONFIG_CPM1 as

arch/powerpc/platforms/Kconfig.cputype has contained the following
comment about CONFIG_8xx item for some years:
"# this is temp to handle compat with arch=ppc"
It looks like not many places still have that old CONFIG_8xx used,
so it is likely to be a good time to get rid of it completely ?
Patchset is composed of the following patches:
[1/8] powerpc: replace CONFIG_8xx by CONFIG_PPC_8xx
[2/8] um: replace CONFIG_8xx by CONFIG_PPC_8xx
[3/8] video: replace CONFIG_8xx by CONFIG_PPC_8xx
[4/8] net: freescale: replace CONFIG_8xx by CONFIG_PPC_8xx
[5/8] tty: cpm_uart: replace CONFIG_8xx by CONFIG_CPM1
[6/8] mtd: replace CONFIG_8xx by CONFIG_PPC_8xx
[7/8] isdn: replace CONFIG_8xx by CONFIG_PPC_8xx
[8/8] powerpc: get rid of CONFIG_8xx
All but the last one are independant and can be applied in any
order. Only the 8th one requires the first 7 patches to be applied.
Sounds good.
I only see 0, 4 and 7 on linuxppc-dev for some reason.
I see them all in linuxppc-dev patchwork.
You'll need to collect ACKs, or get the individual patches merged, and then we
can take patch 8 through the powerpc tree once those are all in - probably for
4.2.
It looks like CONFIG_8xx is used a lot more than CONFIG_PPC_8xx, so it
would be less churn to get rid of the latter (plus, we also have
CONFIG_4xx, CONFIG_6xx, etc). The only use of PPC_8xx I see outside
arch/powerpc is in drivers/watchdog/Kconfig.
Ok, we can do that. But when outside of arch/powerpc/, isn't is more
explicit with CONFIG_PPC_8xx rather that CONFIG_8xx ?
Now that I have submitted the first set of patch, don't we have a risk
that now it is already merged by some other maintainers ?
