I used the following uEnv.txt to boot the Beagleboard XM rev B. I
created a VFAT partition with MLO and u-boot.img on slice 1 and moved
all other partitions up to the next slice by deleting/recreating with
fdisk -c=dos /dev/(device).
uEnv.txt:
abcboard=omap3-beagle-xm
bootpart=0:2
bootfile=boot.scr
bootdir=/
uenvcmd=setenv bootargs console=${console} vram=${vram} root=LABEL=_/ ro
rootwait cgroup_disable=memory fixrtc earlyprintk; ext2load mmc 0:2
0x82000000 /vmlinuz-3.17.4-301.fc21.armv7hl; ext2load mmc 0:2 0x88080000

0x88080000 0x88000000
fdisk (64GB SD card; resize2fs used on root):
