Marvell regulatory domain info storage?

I got some pushback from Quanta yesterday.  They want to put the region 
information in the EEPROM attached to the Marvel device, instead of in 
the manufacturing data area of the SPI FLASH.

I'm not sure of all their rationale; the one point that got through the 
language barrier clearly was the fact that, if it's in EEPROM, there's 
no need to implement a conduit to convey the information from the 
manufacturing data area to the wireless driver.  I also suspect that 
Quanta may be wanting to treat the manufacturing data area as their 
private sandbox.  Both points have some merit.

Up to now, I hadn't been considering the conduit issue.  I tend to thing 
of things in terms of Open Firmware that is well integrated with the 
kernel, in which case such a conduit is "just there".  At present, we 
don't have a convenient conduit.

Quanta has no problem with separately customizing both the SPI FLASH and 
the Marvell EEPROM.
