So there's plenty of examples today of hard-coding that value. Are you worried about a potential future change or an exists today problem you can't otherwise determine the hardware revision of at run-time?

It seems that the changes never reached upstream: git://github.com/01org/edison-u-boot.git branch edison-v2014.04 this branch was implementing 'part info' sub-command which was useful to retrieve partition info. the new repo: git://github.com/edison-fw/u-boot.git branch acpi-v2020.04 does implement 'part number' but does not implement neither 'info' or 'block'. I do not insist for you to take this patch, but I think it is useful (it is the simplest version which supports all needed functionality). If you think the same, let me know. I can change name of the sub-command or implement this in a different way, if needed.

We just aren't at the point where we can't solve this by knowing ahead of time what the blocksize is. I'm sure it will be a problem at some point, but the other part of the problem is figuring out how to add this functionality in an opt-in way that still looks clean when written. If you have some ideas on that however, I'd be happy to review. Thanks! -- Tom -------------- next part -------------- A non-text attachment was scrubbed...
