Ah, I had not realized that this is a text based interface rather than
a small binary blob with fixed offsets.
On the other hand, each line in there could be translated easily into
a separate DT property, and some of them (manfid/prodid, macaddr, ...)
look like they directly correspond to properties we already have.
As Arend said there is also the option of having a chip specific
nvram file (brcmfmac43362-sdio.txt) as a fallback when there is no
more specific module. How many of the lines in your example would
actually differ between the two? Does this affect all of them, or
just a subset that could be turned into a smaller set of DT
properties?
