From: Koen Vandeputte Date: Thu, 11 Jan 2018 11:55:02 +0000 (+0100) Subject: config: support new symbol intro'd in kernel 4.12 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fce35bce0f6e;p=openwrt%2Fstaging%2Fluka.git config: support new symbol intro'd in kernel 4.12 Symbol CONFIG_INITRAMFS_FORCE allows to ignore the value passed by the bootloader. By default, all symbols containing INITRAMFS are wiped from the final config and then re-added conditionally. Add support for this symbol, as the build will stop otherwise questioning the user about this option: * Restart config... * * * General setup * Cross-compiler tool prefix (CROSS_COMPILE) [] Compile also drivers which will not load (COMPILE_TEST) [N/y/?] n ...
