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/ramips/rt3883/config-4.14 | 2 -- target/linux/ramips/rt3883/target.mk | 2 +- 2 files changed, 1 insertion(+), 3 deletions(-) (limited to 'target/linux/ramips/rt3883') diff --git a/target/linux/ramips/rt3883/config-4.14 b/target/linux/ramips/rt3883/config-4.14 index f663d49865..93d803e2ed 100644 --- a/target/linux/ramips/rt3883/config-4.14 +++ b/target/linux/ramips/rt3883/config-4.14 @@ -22,8 +22,6 @@ CONFIG_ARCH_USE_QUEUED_RWLOCKS=y CONFIG_ARCH_USE_QUEUED_SPINLOCKS=y CONFIG_ARCH_WANT_IPC_PARSE_VERSION=y CONFIG_BLK_MQ_PCI=y -# CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE is not set -CONFIG_CC_OPTIMIZE_FOR_SIZE=y CONFIG_CEVT_R4K=y # CONFIG_CEVT_SYSTICK_QUIRK is not set CONFIG_CLKDEV_LOOKUP=y diff --git a/target/linux/ramips/rt3883/target.mk b/target/linux/ramips/rt3883/target.mk index a2631d1ac7..2cc19858e4 100644 --- a/target/linux/ramips/rt3883/target.mk +++ b/target/linux/ramips/rt3883/target.mk @@ -4,7 +4,7 @@ SUBTARGET:=rt3883 BOARDNAME:=RT3662/RT3883 based boards -FEATURES+=usb pci +FEATURES+=usb pci small_flash CPU_TYPE:=74kc DEFAULT_PACKAGES += kmod-rt2800-pci kmod-rt2800-soc wpad-mini -- cgit v1.2.3
