I ran into a problem where the kernel needs to load a vfat module in order to read /boot but the module is on /boot, so it goes to emergency mode. So you need to create a separate vfat partition for MLO and u-boot.img and leave /boot as ext. Make the vfat partition p1 and turn on the bootable flag. (Or else recompile the kernel with vfat built in, not a module.)
So, after spending a lot of time struggling with this, I finally managed to go back to where I was before: i.e., booting, but not able to mount the rootfs.
Here's how my SDCard looks now:

In order to finally get a "working" system, I used Arch[GNU/]Linux's scripts/u-boot/MLO found at http://archlinuxarm.org/platforms/armv7/ti/beagleboard-xm. I don't know why, but I couldn't make the Fedora ones work with this setup...
Anyway, as I said, I'm back to a non-functional system (that, at least, shows me errors when booting Linux). It is still unable to find my root file system by LABEL or UUID, and it still shows me *lots* of errors/warnings when booting Linux.
My question now is: does Fedora 21 really work on a BeagleBoard-xM rev C? I'm starting to believe it doesn't (or that my board is somehow problematic/broken).
Any more ideas? BTW, the uEnv.txt file that I am using is:
mmcargs=setenv bootargs console=ttyO2,115200n8 root=LABEL=_/ ro rootwait cgroup_disable=memory fixrtc earlyprintk
mmcload=ext2load mmc 0:2 0x80000000 uInitrd-3.17.4-301.fc21.armv7hl; ext2load mmc 0:2 0x88000000 dtb-3.17.4-301.fc21.armv7hl/omap3-beagle-xm-ab.dtb; ext2load mmc 0:2 0x88080000 vmlinuz-3.17.4-301.fc21.armv7hl
uenvcmd=run mmcload; run mmcargs; bootz 0x88080000 0x80000000 0x88000000
And I am not using boot.cmd/boot.scr anymore.
Thanks,
