I think it is more complicated than the above. On my 43224, I get
the
message "No SPROM available", which arises because
bcma_sprom_get() is
returning -ENOENT. The reason is that the value tested in "if
(!(sromctrl& BCMA_CC_SROM_CONTROL_PRESENT))" is zero. The
contents of
sromctl are 0x12, and the mask is 1.
This check is the main part of ai_is_sprom_available() in brcmsmac.
If
this check fails, like in your case, brcmsmac tries otp_read_pci() to
read out the sprom, which is not implemented in bcma.
I will try implementing a similar routine in bcma.
I started adding proper OTP support in BCMA, but I am currently working on async firmware loading feature. Different chipsets can either have an external SPROM or on-chip OTP. Some have both, but only one holds the data.

Nice to hear you are working on OTP support in bcma. In that process,
are you also working on making brcmsmac using the sprom provided by bcma?
Hauke
Yep, no sense having it implemented in two places. I think I will do it
in one patch series.
