### Build Instructions

1. Create directory in checked out repo for build files:
```
mkdir build && cd build
```

2. Run configuration for your toolchain:

Baytrail / Cherrytrail:

```
cmake -DTOOLCHAIN=xtensa-byt-elf -DROOT_DIR=`pwd`/../../xtensa-root/xtensa-byt-elf ..
```

Haswell / Broadwell:

```
cmake -DTOOLCHAIN=xtensa-hsw-elf -DROOT_DIR=`pwd`/../../xtensa-root/xtensa-hsw-elf ..
```

Apollolake:

```
cmake -DTOOLCHAIN=xtensa-apl-elf -DROOT_DIR=`pwd`/../../xtensa-root/xtensa-apl-elf ..
```

Cannonlake:

```
cmake -DTOOLCHAIN=xtensa-cnl-elf -DROOT_DIR=`pwd`/../../xtensa-root/xtensa-cnl-elf ..
```

3. Apply default config for your platform.

Baytrail:

```

Cherrytrail:

```
make cherrytrail_defconfig
```

Haswell:

```
make haswell_defconfig
```

Broadwell:

```
make broadwell_defconfig
```

Apollolake:

```
make apollolake_defconfig
```

Cannonlake:

```
make cannonlake_defconfig
```

4. (Optional) Customize your configuration
