Given those patches are relevant to any ARC platform and even ISA version it makes perfect sense for patches to exist in one place instead of being duplicated for each new ARC-based ASIC. Note this is a prerequisite for upstreaming of ARC HS38 support in OpenWRT.

Subject: [PATCH 1/2] openwrt: arc - remove dependency on DEVTMPFS
|
|
|
|
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.
