Subject: [master/dunfell PATCH V5 09/12] recipes-core: images: Add a basic bootstrap base image
Date: Tue, 22 Mar 2022 12:48:05 -0500	[thread overview]
Message-ID: <20220322174808.16341-10-nm@ti.com> (raw)
In-Reply-To: <20220322174808.16341-1-nm@ti.com>

Since we do not wish to modify the tiny-image from anything but really
tiny, lets use that infrastructure and add the bootstrap package group
to create initramfs (not exactly a completely usable system) which can
be used for basic board bringup.

This generates cpio around 36-40MB which should be usually fine for
even smaller systems (Ofcourse, this is much larger than tiny-image
which is around 6MB size). The packages are organized per size to
allow easier customization if desired.
