From 67ed408af20c3b24725f051596028345497219d8 Mon Sep 17 00:00:00 2001 From: Tomasz Maciej Nowak Date: Wed, 18 Mar 2020 19:04:12 +0100 Subject: [PATCH] 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".
