[U-Boot-Users] EEPROM question
Hi,
I have a custom board with PPC 405. The board is designed based on Walnut. But it doesn't have EEPROM. I noticed that if I remove CFG_SPD_EEPROM, compiling u-boot will be failed, because initdram calls spd_sdram. spd_sdram is not definied if CFG_SPD_EEPROM is not defined. Is there any instruction for how to develop without EEPROM?
Thanks,
Frank

I guess you are mixing things up here. "No EEPROM" is probably something else than the SPD EEPROM on your SDRAM DIMMs.

Fix your configuration.
We don't know your hardware so it is difficult to come up with a good recommendation.
If there is just no "normal" EEPROM, then remove EEPROM support (and probably I2C support as well if there is no other device on the I2C bus) from the command definitions.
If there is no SPD EEPROM on your memory chips, then you will have to adjust the initdram() code.
