Re: What to change on u-boot if we want to remove SPD EEPROM?

In message [ref] you wrote:

We want to remove SPD EEPROM on ppc440gp to lower the
expense. The plan is to change u-boot code to use a
memory buffer (filled with the content of SPD EEPROM).
Is this possible?

Yes, it is. Actually only  very  few  systems  use  memory  with  SPD
EEPROMs.

I removed the SPD EEPROM on my ppc440gp board, and
changed u-boot code to use a memory buffer whenever
the code need to access SPD EEPROM, however, I found

You should implement a proper initialization function for your memory
instead.

What extra initialization should I do when SPD EEPROM
is missing from the system?

This depends on your hardware (type of memory etc.).


Please note that such questions ore of topic here. You will  probably
receive more / better response on the u-boot-users mailing list.
