Subject: [PATCH 1/2] powerpc: permanently include 8xx registers in reg.h
Date: Tue, 27 Aug 2019 08:13:07 +0000 (UTC) [thread overview]
Message-ID: <0f7e164afb5d1b022441559fe5a999bb6d3c0a23.1566893505.git.christophe.leroy@c-s.fr> (raw)
Most 8xx registers have specific names, so just include
reg_8xx.h all the time in reg.h in order to have them defined
even when CONFIG_PPC_8xx is not selected. This will avoid
the need for #ifdefs in C code.
Guard SPRN_ICTRL in an #ifdef CONFIG_PPC_8xx as this register
has same name but different meaning and different spr number as
another register in the mpc7450.
