What is the status of the OpenRD-Ultimate support discussed last summer?

Is there no way to detect the board type and use a single U-Boot image for
all three variants?

[U-Boot] last reboot information for u-boot

[sywang]

I have a question about how to save last warm-reboot information. 


I am trying to find a method to save last warm-reboot reason. If I want to
save the information by DRAM memory, how to do this? 



Thanks!

AFAIK, there isn't any direct support to this in u-boot. 
However, this can be achieved in 2 ways.
1. Many Hardware / SOC / Processor has inbuilt registers to detect 
   reason for last reset (HW, WatchDog, SW, or Cold reset). If your platform has any of these, use them

2. while resetting save required info to flash by custom code and read it back upon reset. 

Hope this helps.

AFAIK, there were patch proposals but no final patch. Feel free to look 
up the list archives, find the last post and bump the topic up by 
responding to it, Cc:ing relevant U-boot tree maintainers and the patch 
submitter; if there wasn't, then try to ping the submitter.

We might be going there eventually; for the moment, let us support those 
variants with a 'common plus board-specific config files' approach.
