I built git://git.denx.de/u-boot.git master and I think commit
8a1c44271c55961fb70fb6177f9c02fdb05287c5. Looking at the trace in a little more
detail I see `U-Boot 2013.04-dirty (Jul 10 2013 - 14:02:53)` which seems wrong.
I am now confused.

My uEnv.txt is being read from the mmc ...

] gpio: pin 53 (gpio 53) value is 1
] mmc0 is current device
] micro SD card found
] mmc0 is current device
] gpio: pin 54 (gpio 54) value is 1
] SD/MMC found on device 0
] reading uEnv.txt
] 182 bytes read in 3 ms (58.6 KiB/s)
] Loaded environment from uEnv.txt

That is how I am controlling the boot. Could I be booting from the on-chip flash?
