From cf7154db07c0b8746be290c9e11dcab3c91d237e Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Mon, 9 Jul 2018 20:48:56 +0200 Subject: kernel: only optimized for size if small_flash Add a new config option to allow to select the default compile optimization level for the kernel. Select the optimization for size by default if the small_flash feature is set. Otherwise "Optimize for performance" is set. Add the small_flash feature flag to all (sub)targets which had the optimization for size in their default kernel config. Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new setting. Exceptions to the above are: - lantiq, where the optimization for size is only required for the xway_legacy subtarget but was set for the whole target - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have plenty of space and an optimization for size doesn't make much sense - rb532, which has 128MByte flash Signed-off-by: Mathias Kresin --- target/linux/mcs814x/Makefile | 2 +- target/linux/mcs814x/config-3.18 | 1 - 2 files changed, 1 insertion(+), 2 deletions(-) (limited to 'target/linux/mcs814x') diff --git a/target/linux/mcs814x/Makefile b/target/linux/mcs814x/Makefile index 0f69bbe322..f507842f09 100644 --- a/target/linux/mcs814x/Makefile +++ b/target/linux/mcs814x/Makefile @@ -9,7 +9,7 @@ include $(TOPDIR)/rules.mk ARCH:=arm BOARD:=mcs814x BOARDNAME:=Moschip MCS814x -FEATURES:=usb squashfs low_mem source-only +FEATURES:=usb squashfs low_mem small_flash source-only CPU_TYPE:=arm926ej-s MAINTAINER:=Florian Fainelli diff --git a/target/linux/mcs814x/config-3.18 b/target/linux/mcs814x/config-3.18 index 7f1c5705fd..0b74cd6996 100644 --- a/target/linux/mcs814x/config-3.18 +++ b/target/linux/mcs814x/config-3.18 @@ -26,7 +26,6 @@ CONFIG_ARM_L1_CACHE_SHIFT=5 # CONFIG_ARM_THUMB is not set CONFIG_BINFMT_MISC=y # CONFIG_CACHE_L2X0 is not set -CONFIG_CC_OPTIMIZE_FOR_SIZE=y CONFIG_CLKDEV_LOOKUP=y CONFIG_CLONE_BACKWARDS=y CONFIG_CMDLINE="earlyprintk" -- cgit v1.2.3
