[U-Boot-Users] U-boot runtime detection

[Florian Fainelli]

Hi all,

I am currently working on the adm5120 target under Linux and this board is 
available with at least 4 bootloaders, including U-boot.

We manage getting runtime bootloader detection working using the fw_arg0-3 
values for CFE, RouterBoot, Bootbase. Now I would like to do so for U-boot 
and I could not find any informations if U-boot fills the fw_arg0-3 with some 
specific values that could let us identify it at runtime. Can you indicate me 
if such identification is possible ? If not, would another method (like 
reading the first flash block) work ?

Thank you very much in advance for your answer.
