## Building coreboot

### Preliminaries

Prior to building coreboot the following files are required:
* Intel Flash Descriptor file (descriptor.bin)
* Intel Management Engine firmware (me.bin)
* ITE Embedded Controller firmware (ec.bin)

The files listed below are optional:
- Splash screen image in Windows 3.1 BMP format (Logo.bmp)

These files exist in the correct location in the StarLabsLtd/blobs repo on GitHub which is used in place of the standard 3rdparty/blobs repo.

### Build

The following commands will build a working image:

```bash
make distclean
make defconfig KBUILD_DEFCONFIG=configs/config.starlabs_labtop_cml
make
```
