This patch is for openwrt_12.09 (AA) kernel 3.3.8
It adds the function for the case that having calibration data in eeprom of
wifi pci card.
Compat-wireless provides the way "AH_USE_EEPROM"(see the macro below) to read
the calibration data,
but the ap91_pci_init functionalities does has the correspond API. Thus
ap91_pci_init() is not perfect.
macro in hw.h of compat-wireless
/* ah_flags */
#define AH_USE_EEPROM 0x1
After using the below patch, we can init the card(most of thoes are 5GHz pci
card, such as AR958x) like thie way:
...
ap91_pci_init(NULL, NULL);
...
