Why would stuff from the UEFI firmware be added to the kernel cmdline? and what does that have to do with the DT fixup protocol? Various UEFI interfaces are available from userspace anyway, are you sure that whatever data you are looking for isn't readily available from /sys/ anyway? why must it be kernel command line? > Example : androidboot.serialno is read from firmware and needs to be appended > to kernel commandline I don't know what this is, and what that has to do with uefi, sd-boot or dt? Anyway, the question is very confusing, I am not surprised noone answered so far. Lennart -- Lennart Poettering, Berlin

It > will be really great. If you need paid support for a project that you depend on, I suggest contacting one of the many companies that provide such support. Otherwise, just asking the community to do your work for you again, isn't usually the best way to run a company project :) Why not work with the other developers in your company that have experience with the kernel and these things? Ignoring them feels very odd to me. good luck! greg k-h
