From: Tomasz Maciej Nowak Date: Wed, 18 Mar 2020 18:04:13 +0000 (+0100) Subject: tegra: correct cpu subtype X-Git-Tag: v19.07.3~60 X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=dee8fcfe9f84b584073ca28349c3c04634650744 tegra: correct cpu subtype Tegra 2 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 tegra target 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".
