[U-Boot-Users] Protect an area in RAM

Hi,

Many hardware manufactures provide their development platform with u-boot. I was wondering if there is a feature (did not find anything) in u-boot to protect a specific area in the RAM from being overwritten when u-boot boots a microcontroller? The reason for this is that we store debug information between restarts from our software and using u-boot this is destroyed.

If this feature does not exist, one general solution would be to add a system parameter in which areas that are not to be destroyed could be added as a default feature of u-boot. Would this be a feature that others need as well? If so I will start to investigate what could be done.

Regards,

Markus
