At present having a descriptor means that there is an ME (Intel Management Engine) entry as well. The descriptor provides the ME location and assumes that it is present. For some SoCs this is not true. Before providing the location of a potentially non-existent entry, check if it is present. Update the comment in the ME entry also.

Properties / Entry arguments:

- filename: Filename of file to read into entry
|
|
|
|
This file contains code used by the SoC that is required to make it work.
|
|
The Management Engine is like a background task that runs things that are
|
|
not clearly documented, but may include keyboard, deplay and network
|
|
access. For platform that use ME it is not possible to disable it. U-Boot
|
|
does not directly execute code in the ME binary.
|
|
|
|
A typical filename is 'me.bin'.
|
|
|
|
The position of this entry is generally set by the intel-descriptor entry.
