Depending on the firmware's video options [1] the active SDTV or HDTV mode can yield a framebuffer with noncontiguous horizontal lines, giving a messed up display, for both, u-boot and the loaded kernel.
To always archive the required contiguousness for the used 16bpp, round the framebuffer width down so its aligned to a width of 16.
