My patch has the ability to set the kernel command line appropriately if the video display is configured and enabled in U-Boot. The second variable is used to assist in setting the actual kernel command-line, because that's the easiest and safest way to do it. An alternative that I tried to implement is to have do_bootm_linux() edit the kernel command line directly, removing any existing video= option and putting a new one in, but I found that to be too intrusive, especially since we don't have any good string editing functions already in U-Boot. There are three things that need to be done: 1) The video mode needs to be configured 2) The video display needs to be enabled and the U-Boot console needs to be routed to it 3) The kernel command line needs to be set For #1, we use video-mode. How do you want #2 and #3 handled? -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
