Raumfeld devices are supported by the mainline Linux kernel since version 2.6.33. We only use a minimal patchset with some changes that have not yet gone upstream or are not suitable to go mainline. This set of patches against Linux 2.6.36 can be downloaded here:
A short summary of changes this patchset covers:
- pxa3xx GCU driver (still pending, will hopefully go mainline at some point)
- Disable console cursor
- Raumfeld bootup logo (as framebuffer background)
