Inofficial redpill toolchain image builder

Creates a OCI Container (~= Docker) image based tool chain.
Takes care of downloading (and caching) the required sources to compile redpill.ko and the required os packages that the build process depends on.
Caches .pat downloads inside the container on the host.
Configuration is done in the JSON file global_config.json; custom <platform_version> entries can be added underneath the building_configs block. Make sure the id is unique per block!
Supports a user_config.json per <platform_version>
Supports to bind a local redpill-lkm folder into the container (set "docker.local_rp_lkm_use": "true" and set "docker.local_rp_lkm_path": "path/to/rp-lkm")
Supports to bind a local redpill-load folder into the container (set "docker.local_rp_load_use": "true" and set "docker.local_rp_load_path": "path/to/rp-load")
Supports to clean old image versions and the build cache per <platform_version> or for all of them at once.
Supports to auto clean old image versions and the build cache for the current build image, set "docker.auto_clean":to "true".
Allows to configure if the build cache is used or not ("docker.use_build_cache")
Allows to specify if "clean all" should delete all or only orphaned images.
The default global_config.json contains platform versions provided by the official redpill-load image. Please create new <platform_version> and point them to custom repositories if wanted.
Supports to add custom mounts (set"docker.use_custom_bind_mounts": to "true" and add your custom bind-mounts in "docker.custom_bind_mounts").
Performs integrity check of required kernel/toolkit-dev required for the image build
Supports the make target to specify the redpill.ko build configuration. Set .redpill_lkm_make_target to dev-v6, dev-v7, test-v6, test-v7, prod-v6 or prod-v7. Make sure to use the -v6 ones on DSM6 build and -v7 on DSM7 build. By default the targets dev-v6 and dev-v7 are used.
- dev: all symbols included, debug messages included
- test: fully stripped with only warning & above (no debugs or info)
- prod: fully stripped with no debug messages

Changes

added the additionaly required make target when building redpill.ko
added a new configuration item in .redpill_lkm_make_target to set the build target

Usage

Edit <platform>_user_config.json that matches your <platform_version> according https://github.com/RedPill-TTG/redpill-load and place it in the same folder as redpill_tool_chain.sh
Build the image for the platform and version you want: ./redpill_tool_chain.sh build <platform_version>
Run the image for the platform and version you want: ./redpill_tool_chain.sh auto <platform_version>

You can always use ./redpill_tool_chain.sh run <platform_version> to get a bash prompt, modify whatever you want and finaly execute make -C /opt/build_all to build the boot loader image. After step 3. the redpill load image should be build and can be found in the host folder "images".

Note1: run ./redpill_tool_chain.sh to get the list of supported ids for the <platform_version> parameter. Note2: if docker.use_local_rp_load is set to true, the auto action will not pull latest redpill-load sources. Note3: Please do not ask to add <platform_version> with configurations for other redpill-load repositories.

Feel free to modify any values in global_config.json that suite your needs!

Examples:

See Help text

./redpill_tool_chain.sh
Usage: ./redpill_tool_chain.sh <action> <platform version>

Actions: build, auto, run, clean

- build:    Build the toolchain image for the specified platform version.

- auto:     Starts the toolchain container using the previosuly build toolchain image for the specified platform.
            Updates redpill sources and builds the bootloader image automaticaly. Will end the container once done.

- run:      Starts the toolchain container using the previously built toolchain image for the specified platform.
            Interactive Bash terminal.

- clean:    Removes old (=dangling) images and the build cache for a platform version.
            Use `all` as platform version to remove images and build caches for all platform versions. `"docker.clean_images"`="all" only has affect with clean all.

Available platform versions:
---------------------

Build toolchain image

For Bromolow 6.2.4 : ./redpill_tool_chain.sh build bromolow-6.2.4-25556 For Bromolow 7.0 : ./redpill_tool_chain.sh build bromolow-7.0-41222 For Apollolake 6.2.4 : ./redpill_tool_chain.sh build apollolake-6.2.4-25556 For Apollolake 7.0 : ./redpill_tool_chain.sh build apollolake-7.0-41890

Create redpill bootloader image

For Bromolow 6.2.4 : ./redpill_tool_chain.sh auto bromolow-6.2.4-25556 For Bromolow 7.0 : ./redpill_tool_chain.sh auto bromolow-7.0-41222 For Apollolake 6.2.4 : ./redpill_tool_chain.sh auto apollolake-6.2.4-25556 For Apollolake 7.0 : ./redpill_tool_chain.sh auto apollolake-7.0-41890

Clean old redpill bootloader images and build cache

For Bromolow 6.2.4 : `./redpill_tool_chain.sh clean bromolow-6.2.4-25556` For Bromolow 7.0 : `./redpill_tool_chain.sh clean bromolow-7.0-41222` For Apollolake 6.2.4 : `./redpill_tool_chain.sh clean apollolake-6.2.4-25556` For Apollolake 7.0 : `./redpill_tool_chain.sh clean apollolake-7.0-41890` For all : `./redpill_tool_chain.sh clean all`

Теперь инструкция сводиться к:

Распаковываем в удобное место
В файле _user_config.json правим vid, pid, sn, mac

chmod +x redpill_tool_chain.sh 4. ./redpill_tool_chain.sh build -7.0.1-42218 5. ./redpill_tool_chain.sh auto -7.0.1-42218 6. В папке images будет образ загрузчика, пишем любым удобным способом на флешку. В папке cache будет pat фай с нужной версией DSM для установки в мастере.
