So I did that - the offset is printed out as 0x0830
(BCMA_CC_SPROM_PCIE6). And when I change the offset to 0x0800
(BCMA_CC_SPROM), the complaint about SPROM version goes away.

IOW, these messages no longer exist:

[    0.815750] bcma: Unsupported SPROM revision: 255
[    0.815804] bcma: No SPROM available

but that doesn't actually make anything *work*. The brcms errors still
remain the same.

So the SPROM issue seems to be real, but irrelevant.

I also noticed that the CONFIG_BRCMDBG onyl enables pr_debug(), but
doesn't actually #define DEBUG, so pr_debug() gets compiled out
anyway.

I'll try with -DDEBUG in the brcm80211 subdirectory and see if I get
more interesting output that way.
