Noticed the file used by some of the Allwinner boards contains:

https://build.opensuse.org/package/view_file/hardware/bcm43xx-firmware/brcmfmac43362-sdio-cubietruck.txt

==
# Board Revision is P307, same nvram file can be used for P304, P305, 
P306 and P307 as the tssi pa params used are same
#Please force the automatic RX PER data to the respective board 
directory if not using P307 board, for e.g. for P305 boards force the 
data into the following directory 
/projects/BCM43362/a1_labdata/boardtests/results/sdg_rev0305
==

So apparently some values involve low-level hardware tuning, and it's 
possible you need a different file if the PCB layout of the board you 
are using is changed at some point.

This makes it kinda difficult to have a common rootfs for more than one 
board.
Would be nice if they moved those values to device tree.



Yours sincerely,
