From ade9eba1496bb01acc03731c4ccb5369802b73ac Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Mon, 8 May 2023 18:09:23 +0200 Subject: [PATCH] ipq806x: 5.15: drop arm override compile patch Drop arm override compile patch. The use is dubious and at times (2016) it was never explained why this was required. Krait CPU and Cortex-a15 may be similar but they have some intrinsic difference. While very similar they differ a lot in additional feature and also cache configuration. Also these conflict with raid6 libraty compilation that use specific workaround not compatible with cortex-a15 and produce compilation warning. Fix compilation warning: cc1: error: switch '-mcpu=cortex-a15' conflicts with switch '-march=armv7-a+simd' [-Werror] cc1: all warnings being treated as errors Signed-off-by: Christian Marangi --- .../0065-arm-override-compiler-flags.patch | 21 ------------------- 1 file changed, 21 deletions(-) delete mode 100644 target/linux/ipq806x/patches-5.15/0065-arm-override-compiler-flags.patch diff --git a/target/linux/ipq806x/patches-5.15/0065-arm-override-compiler-flags.patch b/target/linux/ipq806x/patches-5.15/0065-arm-override-compiler-flags.patch deleted file mode 100644 index a1a0371fbc..0000000000 --- a/target/linux/ipq806x/patches-5.15/0065-arm-override-compiler-flags.patch +++ /dev/null @@ -1,21 +0,0 @@ -From 4d8e29642661397a339ac3485f212c6360445421 Mon Sep 17 00:00:00 2001 -From: John Crispin -Date: Thu, 9 Mar 2017 09:33:32 +0100 -Subject: [PATCH 65/69] arm: override compiler flags - -Signed-off-by: John Crispin ---- - arch/arm/Makefile | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - ---- a/arch/arm/Makefile -+++ b/arch/arm/Makefile -@@ -61,7 +61,7 @@ KBUILD_CFLAGS += $(call cc-option,-fno-i - # macro, but instead defines a whole series of macros which makes - # testing for a specific architecture or later rather impossible. - arch-$(CONFIG_CPU_32v7M) =-D__LINUX_ARM_ARCH__=7 -march=armv7-m --arch-$(CONFIG_CPU_32v7) =-D__LINUX_ARM_ARCH__=7 -march=armv7-a -+arch-$(CONFIG_CPU_32v7) =-D__LINUX_ARM_ARCH__=7 -mcpu=cortex-a15 - arch-$(CONFIG_CPU_32v6) =-D__LINUX_ARM_ARCH__=6 -march=armv6 - # Only override the compiler option if ARMv6.
