  4. Subject: [PATCH 1/2] openwrt: arc - remove dependency on DEVTMPFS
  5. OpenWRT builds initramfs so that it doesn't require DEVTMPFS so dropping
  6. this dependency. That helps to escape 2 separate kernel rebuilds with
  7. and without initramfs.
  8. 2 builds happen because OpenWRT first builds kernel and later modules.
  9. When building entire kernel with simple "make" INITRAMFS sets to a real
  10. value and so was triggering DEVTMPFS selection. Then when building only
  11. modules with "make modules" command INITRAMFS is zeroed and so kernel
  12. config was changing that lead to full kernel rebuild.
