From: Tomasz Maciej Nowak Date: Wed, 18 Mar 2020 18:04:12 +0000 (+0100) Subject: mvebu: cortexa9: correct cpu subtype X-Git-Tag: v21.02.0-rc1~3293 X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=2d61f8821c7cf99354e904139226c132554ba180;hp=43d1d88510621801d66a0a7f46f4c4f44d89633a mvebu: cortexa9: correct cpu subtype Armada 370 processors have only 16 double-precision registers. The change introduced by 8dcc1087602e ("toolchain: ARM: Fix toolchain compilation for gcc 8.x") switched accidentally the toolchain for mvebu cortexa9 subtarget to cpu type with 32 double-precision registers. This stems from gcc defaults which assume "vfpv3-d32" if only "vfpv3" as mfpu is specified. That change resulted in unusable image, in which kernel will kill userspace as soon as it causing "Illegal instruction".
