Noisefloor calibration involves querying hardware for samples and storing this information on a history buffer in hardware for actual noisefloor calibration processing in hardware. The history buffer supports collecting information for all Atheros hardware, one history buffer slot for each chain on each channel used for MIMO operation. For current hardware this means one history buffer slot for each chain on both the control (or primary) channel and the extension (or secondary) channel. We know which noisefloor registers to poke for collecting noisefloor data through the chainmask. For AR9285 and AR9271 devices, both 1x1, the chaimmask is defined as 0x9 = 0b0001001. The first four bits represent each chain out of a maximum of 4 chains [0-3] on the primary channel. The last four bits represent each chain on the extension channel. A chainmask of 0x9 therefore indicates chain 1 is active on both the primary and the extension channel. AR9271 only requires collecting and storing noisefloor history buffer data for the first chain on both the control and extension channel (nfarray[0] and nfarray[3]) so fix the code and avoid which reads and writes to the history buffer for the other chains. Since the noisefloor varies depending on the number of chains your device supports also initialize the noisefloor history buffer with reasonable values seen on 1x1 devices such as AR9285.
