Then I realized that the old omapfb driver also contains SRAM code, removing of which which wasn't such a simple task. I think I got that solved, but it needs still cleaning up. But this again reminded me of the mess of having two display drivers, the old omapfb and the new DSS2. Many of the OMAP2 boards using the old driver should be quite easy to port to DSS2, with the exception of N800. DSS2 doesn't support OMAP1, so there's not much that can be done with those boards currently. What is the status of OMAP1 support in general? Is having a working framebuffer for OMAP1 boards something we need? Will there be a single kernel config containing OMAP1 and OMAP2+ support in the future? This will cause problems, as the old and new display drivers cannot coexist currently. I have never worked with an OMAP1 board, and I don't own one, and thus I don't have any experience on OMAP1 display HW. This will make any work I do on OMAP1 omapfb slightly difficult, but if there's clear need for OMAP1 fb, then I think the only way to go is to convert the old omapfb driver to an OMAP1 framebuffer driver. But whatever is decided on OMAP1 fb, I'll start converting the OMAP2 drivers to the new DSS2. Tomi
