linux: initramfs: use initramfs config file(s) and directory structure

[dhewg]

This was a PR created by @mglae at my fork (for whatever reason).
Cleaned up and rebased .

Do we still need cpio:host?

The two configs:

packages/linux/initramfs.conf 
projects/Generic/linux/initramfs.x86_64.conf

I'm wondering if they should be associated with the initramfs package, rather than linux?

They should also be in a config sub-dir, ie.

packages/initramfs/config/initramfs.conf 
projects/Generic/packages/initramfs/config/initramfs.x86_64.conf

(Yes, the location of the linux kernel configs is a historical anachronism)

[dhewg]

Indeed, it looks like we don't need the cpio dependency anymore, linux's usr/gen_init_cpio.c creates the archive itself. Removed it.
Also moved the config files to initramfs/config

@dhewg thanks for updating the PR, however you've created:

projects/Generic/initramfs/config/initramfs.x86_64.conf

when this should be:

projects/Generic/packages/initramfs/config/initramfs.x86_64.conf

in order to maintain the correct package hierarchical structure.

I'd rather we don't create more package-specific subdirs in the root of each project (or device) - kodi and linux are pretty much the only two that do this, for legacy reasons (and we could/should tidy them up at some point, certainly kodi).

[MilhouseVH]

Tested with Generic and RPi2 builds, all looks good to me - thanks!

@HiassofT can you rebase this ('cpio` was bumped in #4210)

[HiassofT]

@MilhouseVH no, that's not my PR :-)

[MilhouseVH]

Doh, sorry! Ping @dhewg 😄

[dhewg]

Done ;)
