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/generic/config-4.9 | 2 -- 1 file changed, 2 deletions(-) (limited to 'target/linux/generic/config-4.9') diff --git a/target/linux/generic/config-4.9 b/target/linux/generic/config-4.9 index 83abfdc8ff..011172b7af 100644 --- a/target/linux/generic/config-4.9 +++ b/target/linux/generic/config-4.9 @@ -680,8 +680,6 @@ CONFIG_CARDBUS=y # CONFIG_CAVIUM_OCTEON_SOC is not set # CONFIG_CB710_CORE is not set # CONFIG_CC10001_ADC is not set -# CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE is not set -CONFIG_CC_OPTIMIZE_FOR_SIZE=y # CONFIG_CC_STACKPROTECTOR is not set CONFIG_CC_STACKPROTECTOR_NONE=y # CONFIG_CC_STACKPROTECTOR_REGULAR is not set -- cgit v1.2.3
