Even without a proper fix this should not be done unconditionally. Please do this only when you actually have to, i. e. when really using the HDMI framebuffer in a system. It's not a good idea to let all others suffer from that. Also, I wonder if we should issue a warning then (at build time). Best regards, Wolfgang Denk

Currently HDMI framebuffer only works if we disable data cache. Disable data cache until the proper fix is found.
