| Some PSP implementations allow storing SMU firmware into cbfs and |
| calling the PSP to load the blobs at the proper time. |
| |
| The soc/<codename> should select this if its PSP supports the feature |
| and each mainboard can choose to select an appropriate fanless or |
| fanned set of blobs. Ask your AMD representative whether your APU |
| is considered fanless. |
