This patch-set adds support for building barebox with an auxiliary config.
It can be used to build the barebox x-loader or MLO (also called Secondary
Program Loader) in addition to the standard barebox build (Tertiary Program
Loader). This implements the design proposed in
http://elinux.org/Buildroot#Todo_list, with minor adjustments:
1. Have boot/barebox contain the common stuff.
2. Move the non-shared parts to boot/barebox/barebox and duplicate it in
boot/barebox/barebox-aux.
3. There is only one version selection, but each package allows to
define the configuration to be used.
4. Design is a little bit like package/gcc, where we have multiple gcc builds,
but share a lot of common definitions between the packages.
To demonstrate that it works as advertized, the last patch adds a defconfig for
the beaglebone that makes use of the added functionality.
Revision history:
v6: Review rework based on feedback from Thomas Pettazoni:
- Second config build renamed to auxiliary build.
- Primary package build moved to boot/barebox/barebox to keep things symmetric.
- Dropped already merged parts of series.
v5: Review rework based on feedback from Arnout Vandecappelle, Yegor Yefremov
and Thomas Petazzoni:
- Dropped support to rename output/images (same can be achieved with
genimage)
- Simplified barebox INSTALL_IMAGE_CMDS
- Simplified KConfig option naming
- Appends test defconfig to last commit message
Improvements to the BBB barebox test config:
- Latest kernel and headers
- Tunes barebox.env to boot from eMMC/SD
- Use genimage to generate a full sdcard.img
v4: Introduces barebox-package function to reduce duplication and maintenance
Simplifies built image selection
Ease review with smaller patches
Review re-work: Special thanks to Arnout Vandecappelle and Yegor Yefremov
v3: Updated for master at 544e2c5871f223facd1ab3c2853cd07ad70dd9d1
v2: Dropped x-loader build specialization in favor of 2 generic barebox builds
v1: Initial posting
