[PATCH 08/12] powerpc/8xx: Getting rid of remaining use of CONFIG_8xx

Christophe Leroy christophe.leroy at c-s.fr
Tue Aug 8 21:58:54 AEST 2017


Two config options exist to define powerpc MPC8xx:
* CONFIG_PPC_8xx
* CONFIG_8xx

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"

arch/powerpc is now the only place with remaining use of
CONFIG_8xx: get rid of them.
