That helps to escape 2 separate kernel rebuilds with +and without initramfs. + +2 builds happen because OpenWRT first builds kernel and later modules. +When building entire kernel with simple "make" INITRAMFS sets to a real +value and so was triggering DEVTMPFS selection. Then when building only +modules with "make modules" command INITRAMFS is zeroed and so kernel +config was changing that lead to full kernel rebuild. + +Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> +--- + arch/arc/Kconfig | 2 -- + 1 file changed, 2 deletions(-) + +--- a/arch/arc/Kconfig ++++ b/arch/arc/Kconfig +@@ -12,8 +12,6 @@ config ARC + select BUILDTIME_EXTABLE_SORT + select COMMON_CLK + select CLONE_BACKWARDS +- # ARC Busybox based initramfs absolutely relies on DEVTMPFS for /dev +- select DEVTMPFS if !INITRAMFS_SOURCE="" + select GENERIC_ATOMIC64 + select GENERIC_CLOCKEVENTS + select GENERIC_FIND_FIRST_BIT |
