u-boot for MNT Reform build script
----------------------------------

Work in progress script for building uboot for the MNT Refom 2 computer.

## Howto

To compile the script, you'll need to install some packages. On Debian :

```
apt install -y --no-install-recommends gcc-aarch64-linux-gnu \
                      device-tree-compiler \ 
                      make \
                      bc \
                      build-essential \
                      bison \
                      flex \
                      bash \
                      git \
                      ca-certificates
```

You just need to launch `make_uboot.sh`. By default, script build uboot with
sdcard support. to build it with emmc support you need to pass the `emmc`
argument:

```
./make_uboot.sh emmc
```

You can also define `UBOOT_BUILD` environment variable with `emmc` or `sdcard`
variable.

The `flash.bin` is located in the `u-boot/` directory.

## Build with docker

Build the image :

```
docker build -t reform_kernel_build .
```

Then run the container with  with a directory mapped to `/output`:

```
docker run -v /home/docker/output:/output --env UBOOT_BUILD=sdcard --rm reform_kernel_build
```

You could pass the  `UBOOT_BUILD` environment variable to your container do tell
`make_uboot.sh` which version to compile :

 * `sdcard` or not defined if you'll install to the SDCard
 * `emmc` for the internal memomry of the IMX card

Flash.bin file will be in the directory mapped to `/output` in the
container.
