Let resume depend on a newly flashed bootloader makes it a showstopper for a lot of people. Using gen-blob for all kind of stuff that the flashed blob gets wrong for init the hardware is great and easy to do as we can leave the first bootloader in place. On the other hand we have to rely on the first bootloader for the resume. And frankly, I see no way around this when we like to reach an audience bigger then three people that are brave enough for flashing a new bootloader. I hope I have the facts still right in my mind, so please correct me here if I'm wrong. With the standard bootloader Moto uses the approach to write a special bit muster into the first ram page, the bootloader checks this pages and resumes, instead of completely re-init, the machine. Problem is that such a reserved first-page is not really loved in the kernel community. I hope this was all right so far. While there are some machines inside the kernel that have such a mechanism it is not very likely that we can push it in for our machine, too. We still can have such a patch locally. I know, merging all in the kernel is the goal, and you guys know that I'm in favour of this like you are. But being realistic it is also unlikely that we will be able to push all stuff upstream. There will always be some sort of small patches that we need, but get not accepted mainline. If I balance the facts that we a) keep a local hack or b) only have resume for people with a newly flashed bootloader, I go for a without doubt. regards Stefan Schmidt
