[OE-core] [PATCH 0/1] wic: Add wic support to generate rootfs image for uboot

[Adrian Calianu]

Hi,

We tried to extend existing wic tool to generates rootfs images for U-Boot.
This will be possible from cooked mode(existing build folder) and from raw 
mode where you have to provide a list of packages to be installed and 
a native rootfs with necessary tools. 

Some prerequisites are required for this new build setup in wic.conf file. 
As package manager only opkg and only web paths(repourl) are supported by now.
../poky/scripts/lib/image/config/wic.conf
[create]
arch=target_arch (example: powerpc, arm, x86)
pkgmgr=opkg
repourl=http://example.distro/p2020rdb/ipk/all http://example.distro/p2020rdb/ipk/p2020rdb http://example.distro/p2020rdb/ipk/ppce500v2

    1) Build rootfs image from an existing bitbake build:
       wic create ../poky/scripts/lib/image/canned-wks/uboot.wks -e core-image-minimal -o .../output

    2) Build rootfs image from an existing rootfs and native_sysroot:
       wic create ../poky/scripts/lib/image/canned-wks/uboot.wks -r .../path_to_rootfs -n .../path_to_native_sysroot -o .../output

    3) Build rootfs image only from a package list (on wks file) similar with IMAGE_INSTALL from bitbake. 
       Package dependencies will be installed by default by the package manager.

       Add the list of packages to be installed as rootfs on ../poky/scripts/lib/image/canned-wks/uboot.wks:
       %packages
       packagegroup-core-boot
       pramfs-init
       run-postinsts
       packagegroup-core-ssh-dropbear
       %end

       Generate rootfs image:
       wic create ../poky/scripts/lib/image/canned-wks/uboot.wks  -n .../path_to_native_sysroot -o .../output
