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/adm5120/Makefile | 2 +- target/linux/adm5120/config-3.18 | 1 - target/linux/at91/config-4.9 | 2 -- target/linux/ath79/tiny/config-default | 2 -- target/linux/au1000/Makefile | 2 +- target/linux/au1000/config-3.18 | 1 - target/linux/generic/config-3.18 | 1 - target/linux/generic/config-4.14 | 2 -- target/linux/generic/config-4.9 | 2 -- target/linux/lantiq/config-4.14 | 2 -- target/linux/layerscape/armv8_32b/config-4.9 | 2 -- target/linux/layerscape/armv8_64b/config-4.9 | 2 -- target/linux/mcs814x/Makefile | 2 +- target/linux/mcs814x/config-3.18 | 1 - target/linux/mediatek/mt7622/config-4.14 | 2 -- target/linux/ppc40x/Makefile | 2 +- target/linux/ppc40x/config-3.18 | 1 - target/linux/ppc44x/Makefile | 2 +- target/linux/ppc44x/config-3.18 | 1 - target/linux/ramips/mt7620/config-4.14 | 2 -- target/linux/ramips/mt76x8/config-4.14 | 2 -- target/linux/ramips/rt288x/config-4.14 | 2 -- target/linux/ramips/rt288x/target.mk | 1 + target/linux/ramips/rt305x/config-4.14 | 2 -- target/linux/ramips/rt305x/target.mk | 2 +- target/linux/ramips/rt3883/config-4.14 | 2 -- target/linux/ramips/rt3883/target.mk | 2 +- target/linux/rb532/config-4.9 | 1 - 28 files changed, 8 insertions(+), 40 deletions(-) (limited to 'target/linux') diff --git a/target/linux/adm5120/Makefile b/target/linux/adm5120/Makefile index 56916bdcea..fbfaf6d23c 100644 --- a/target/linux/adm5120/Makefile +++ b/target/linux/adm5120/Makefile @@ -9,7 +9,7 @@ include $(TOPDIR)/rules.mk BOARD:=adm5120 BOARDNAME:=Infineon/ADMtek ADM5120 -FEATURES:=low_mem source-only +FEATURES:=low_mem small_flash source-only SUBTARGETS:=router_le router_be rb1xx INITRAMFS_EXTRA_FILES:= diff --git a/target/linux/adm5120/config-3.18 b/target/linux/adm5120/config-3.18 index 000424c2e4..231877e6a0 100644 --- a/target/linux/adm5120/config-3.18 +++ b/target/linux/adm5120/config-3.18 @@ -45,7 +45,6 @@ CONFIG_ARCH_SUSPEND_POSSIBLE=y CONFIG_ARCH_WANT_IPC_PARSE_VERSION=y CONFIG_ARM_AMBA=y CONFIG_BUILD_BIN2C=y -CONFIG_CC_OPTIMIZE_FOR_SIZE=y CONFIG_CEVT_R4K=y CONFIG_CLONE_BACKWARDS=y CONFIG_CMDLINE="console=ttyAM0,115200 rootfstype=squashfs,jffs2" diff --git a/target/linux/at91/config-4.9 b/target/linux/at91/config-4.9 index 6ccc34b957..a44d3ac522 100644 --- a/target/linux/at91/config-4.9 +++ b/target/linux/at91/config-4.9 @@ -58,8 +58,6 @@ CONFIG_BLK_DEV_SD=y #
