[U-Boot-Users] Support for AMD Flash SecSi Sector

Hi,

we use an AMD 29LV640D flash on our MCF5272 board. This flash has a 128 Word sector called SecSi which is one time programmable. We'd like to use the SecSi sector of the flash to store board information, as serial number and ethernet MAC address.

I'll start to implement support for the SecSi sector in u-boot. Is there anybody, still working on this topic? Are there any suggestions how to implement it?

I think of adding some special commands in cmd_flash.c to read and prog the SecSi sector. Additionally I would change the read function for the "ethaddr" to use the SeCsi sector instead of the environment.

Regards,
