[U-Boot] Loop Variable through to user space

Hi all,

during the execution of th MLO I create a variable, whose value I want to make accessible to user space applications in Android. How can this be achieved?

One way would be to write the contents of the variable to external memory and let it read by the user space process. However, I would need to make sure that during boot no other process is overwriting the address.

Do you know of any other ways?

Best, André
