Omar, give it a try.... compile uImage and omap4-panda.dtb.
Have the u-boot load them and run by

 # setenv initrd_high "0xffffffff" ; setenv fdt_high "0xffffffff"
 # mmc rescan 0; fatload mmc 0:1 0x80200000 uImage; fatload mmc 0:1
0x81600000 uInitrd; fatload mmc 0:1 0x815f0000 omap4-panda.dtb
 # setenv bootargs "console=tty0 console=ttyO2,115200n8
root=/dev/mmcblk0p2 rootwait ro earlyprintk fixrtc nocompcache
vram=48M omapfb.vram=0:24M mem=456M at 0x80000000 mem=512M at 0xA0000000"
 #  bootm 0x80200000 0x81600000 0x815f0000

hth.
