Re: [U-Boot] framebuffer and video on mx51 babbage

I would hate to reinvent a wheel that just needs some final touches, and of course anything I might contribute would be released. At the moment, the mx51evk is not yet ported to the last u-boot release, where relocation takes place even for ARM - so you get an error if you try to compile with the last release. I have not a board at the moment, but I think I can have it for some time very soon to make the required changes. No surprise if (as other ARM based boards) if the imx51evk does not compile at the moment. I'm very interested in those patches, regardless of their state. If there is anyway you can get those out that would be very appreciated. Patches will be sent, as usual, to the ML for review. Then everyone can take them and, if it is possible, test them and send feedback.
