+omapfb.vram_cache=<y|n>
+ - Sets the framebuffer memory to be write-through cached. This may be
+ useful in the configurations where only CPU is allowed to write to
+ the framebuffer and eliminate the need for enabling shadow
+ framebuffer in Xorg DDX drivers such as xf86-video-fbdev and
+ xf86-video-omapfb. Enabling write-through cache is only useful
+ for ARM11 and Cortex-A8 processors. Cortex-A9 does not support
+ write-through cache well, see "Cortex-A9 behavior for Normal Memory
+ Cacheable memory regions" section in Cortex-A9 TRM for more details.
