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:

  Disk /dev/mmcblk0: 14.9 GiB, 16021192704 bytes, 31291392 sectors
  Units: sectors of 1 * 512 = 512 bytes
  Sector size (logical/physical): 512 bytes / 512 bytes
  I/O size (minimum/optimal): 512 bytes / 512 bytes
  Disklabel type: dos
  Disk identifier: 0x00000000

  Device         Boot   Start     End Sectors  Size Id Type
  /dev/mmcblk0p1 *         63  144584  144522 70.6M  c W95 FAT32 (LBA)
  /dev/mmcblk0p2       145408 1144831  999424  488M 83 Linux
  /dev/mmcblk0p3      1144832 1394687  249856  122M 82 Linux swap / Solaris
  /dev/mmcblk0p4      1394688 4128767 2734080  1.3G 83 Linux

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,
