PS1, Line 56: if (fw_config_probe(FW_CONFIG(AUDIO_AMP, AMP_MAX98390))) {
It looks like the configuration for MAX98390 and TAS2563 are the same in coreboot.
If we only differentiate the AMPs in payload, you can just write
```
if (fw_config_probe(FW_CONFIG(AUDIO_AMP, AMP_MAX98390)) ||
    fw_config_probe(FW_CONFIG(AUDIO_AMP, AMP_TAS2563))) {
    ...
)
```

PS1, Line 4: AUDIO_AMP
do we reserve the bits for NAU8318 ?
