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/mediatek/mt7622/config-4.14 | 2 -- 1 file changed, 2 deletions(-) (limited to 'target/linux/mediatek') diff --git a/target/linux/mediatek/mt7622/config-4.14 b/target/linux/mediatek/mt7622/config-4.14 index ce705e58f5..15cd47a4ae 100644 --- a/target/linux/mediatek/mt7622/config-4.14 +++ b/target/linux/mediatek/mt7622/config-4.14 @@ -88,8 +88,6 @@ CONFIG_BT_HCIUART=y CONFIG_BT_HCIUART_SERDEV=y CONFIG_BT_HCIVHCI=y CONFIG_BUILD_BIN2C=y -# CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE is not set -CONFIG_CC_OPTIMIZE_FOR_SIZE=y CONFIG_CLKDEV_LOOKUP=y CONFIG_CLKSRC_MMIO=y CONFIG_CLOCK_THERMAL=y -- cgit v1.2.3
