What do you mean, you don't need xloader, u-boot SPL can replace it.
Yes and no. No, becaue you nor I have no Nokia's signing key(s) to sign SPL binary for OMAP's secure boot ROM. IIRC N950/N9 is even more strict regarding that, am I right?
You are right, we cannot sign SPL binary for N900 because we do not have key. Signing key has only somebody in Nokia (or in TI). I do not have N950/N9 so I do not know anything about new devices.
Probably autobuilder does have a key, but the question is if key is different for each device or not.
There are more (about 80) HW revisions of Nokia N900. And only 5 different X- Loader images (which are part of public Nokia N900 firmware).
So max. 5 different keys for all N900 devices. (or maybe in one X-Loader image are more signatures?)
I know. So ... ? Basically you can use the TI flashes too since it all goes through the bootrom, right?
Butrom requires signed binary.
Yes and format of signed binary is not published by TI (there are only some RE info about Motorola Omap devices).
Well, format is somewhat documented in public TI specifications, but that won't help anyway becase of OMAP's little OTP memory...
If you find can you write link for that specification?
