How to hack EEPROM-less cards¶
EEPROM data located in flash at well known address, it have signature so can be auto-detected by GEOM
- Load EEPROM into firmware(9) subsystem, just after VM initialization done. Think sys/mips/atheros/apb.c is good place for such hack.
- Load it by special GEOM module into firmware(9), good only if ath(4) driver loaded as kld in userland.
