Author: ray Date: Sun Jan 13 22:05:46 2013 New Revision: 245389 URL: http://svnweb.freebsd.org/changeset/base/245389 Log: Enable syscons framebuffer support for bcm2835. It makes possible to run Xorg on Raspberry Pi. o convert mmap address to physical. o add FBIOGTYPE ioctl handler - allow to get screen resolution by new xf86-video-scfb driver. Originally designed for "Efika MX" project.
