The default rootfs image for the AM57XXEVM has one /dev/fb0 framebuffer device. How can we enable 2 more devices, /dev/fb1 and /dev/fb2?
The wiki indicates that you can allocate vram on your u-boot bootargs for the kernel and so we tried the following:
console=ttyO2,115200n8 root=/dev/nfs nfsroot=192.168.1.22:/home/fluke/processor-sdk-linux-image-am57xx-evm/targetNFS,nolock,v3,tcp,rsize=4096,wsize=4096 rw ip=dhcp vram=16M omapfb.vram=0:8M,1:4M,2:4M
However, there is only 1 framebuffer device present after this:
root@am57xx-evm:/sys/devices/platform/omapdrm.0/graphics/fb0# ls
bits_per_pixel cursor mode pan state uevent
blank dev modes power stride virtual_size
console device name rotate subsystem
Is there a wiki page on how to do this? Are the DSS commands similar to the previous OMAP platforms as described below?

Thank you,
