### Build Instructions

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

2. Run configuration for your toolchain:

Baytrail:

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

Cherrytrail:

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

```
make baytrail_defconfig
```

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

```
make menuconfig
```

5. Build firmware

```
make bin
# or `make bin -j<jobs>` for parallel build
```
