Third-party firmware PoC...

We've known from the beginning that on the Prime, Linux would be easier to port than it was on the Nspire, because the S3C2416 has a public datasheet, and is already largely supported by Linux. Some outdated forks of QEMU contain support for the S3C241x and S3C244x series. TI-Planet's hpwiki contains pointers to those.

Porting Linux to the Prime requires more technical skill than my PoC, which represents only several hours of work, and didn't learn me much in the way of new things (the -n flag for ld, the --set-start flag for objcopy, and that's about it), because I had already done DummyOS for my OSLauncher on the Nspire.
Before porting Linux, we need to somehow obtain more information on the pin assignments (e.g. GPIO for the keyboard ?), through reverse-engineering and/or help.
