From: Pali Rohár Date: Sat, 27 Aug 2022 13:44:54 +0000 (+0200) Subject: powerpc/boot: Explicitly disable usage of SPE instructions X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=110a58b9f91c66f743c01a2c217243d94c899c23;p=linux.git powerpc/boot: Explicitly disable usage of SPE instructions uImage boot wrapper should not use SPE instructions, like kernel itself. Boot wrapper has already disabled Altivec and VSX instructions but not SPE. Options -mno-spe and -mspe=no already set when compilation of kernel, but not when compiling uImage wrapper yet. Fix it.
