In the end, I dropped this patch, and decided to just have U-Boot create this DT node itself from scratch, just like Olof did for the Samsung ARM Chromebook. I have however applied patch 2/2, to enable the simplefb driver in bcm2835_defconfig.

Place a template simple-framebuffer device into the RPi device tree. The bootloader is expected to fill in all the parameters at boot time. Hence, disable the device by default, so if the bootloader doesn't do this, the device isn't activated with invalid parameters.
