Subject: [PATCH 1/2] openwrt: arc - remove dependency on DEVTMPFS
|
2015-11-22 19:06:07 +00:00
|
|
|
|
|
|
|
|
OpenWRT builds initramfs so that it doesn't require DEVTMPFS so dropping
|
|
|
|
|
this dependency. 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.
