LLVM IAS does not support it but PPC970 seems to be using it. This switches dssall to .long as there is no much point in fixing LLVM.

The dssall ("Data Stream Stop All") instruction is obsolete altogether
with other Data Cache Instructions since ISA 2.03 (year 2006).

LLVM IAS does not support it but PPC970 seems to be using it.
This switches dssall to .long as there is no much point in fixing LLVM.

powerpc: change CONFIG_6xx to CONFIG_PPC_BOOK3S_32 2018-11-26T11:33:37+00:00 Christophe Leroy christophe.leroy@c-s.fr 2018-11-17T10:24:56+00:00 d7cceda96badc1bd444cff27ab9c375a1277c1e3 Today we have: config PPC_BOOK3S_32 bool "512x/52xx/6xx/7xx/74xx/82xx/83xx/86xx" [depends on PPC32 within a choice] config PPC_BOOK3S def_bool y depends on PPC_BOOK3S_32 || PPC_BOOK3S_64 config 6xx def_bool y depends on PPC32 && PPC_BOOK3S 6xx is therefore redundant with PPC_BOOK3S_32.

Today we have:

config PPC_BOOK3S_32
	bool "512x/52xx/6xx/7xx/74xx/82xx/83xx/86xx"
	[depends on PPC32 within a choice]

config PPC_BOOK3S
	def_bool y
	depends on PPC_BOOK3S_32 || PPC_BOOK3S_64

config 6xx
	def_bool y
	depends on PPC32 && PPC_BOOK3S

6xx is therefore redundant with PPC_BOOK3S_32.

In order to make the code clearer, lets use preferably PPC_BOOK3S_32.
This will allow to remove CONFIG_6xx in a later patch.
