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-3.18 | 1 - 1 file changed, 1 deletion(-) (limited to 'target/linux/generic/config-3.18') diff --git a/target/linux/generic/config-3.18 b/target/linux/generic/config-3.18 index 0f66960fdc..0eec5c65d6 100644 --- a/target/linux/generic/config-3.18 +++ b/target/linux/generic/config-3.18 @@ -580,7 +580,6 @@ CONFIG_CAVIUM_OCTEON_HELPER=y # CONFIG_CAVIUM_OCTEON_SIMULATOR is not set # CONFIG_CAVIUM_OCTEON_SOC is not set # CONFIG_CB710_CORE is not set -# CONFIG_CC_OPTIMIZE_FOR_SIZE is not set # CONFIG_CC_STACKPROTECTOR is not set CONFIG_CC_STACKPROTECTOR_NONE=y # CONFIG_CC_STACKPROTECTOR_REGULAR is not set -- cgit v1.2.3
