Once I get the image file into memory, is there a uboot function I can
call to run it? One that copies it to the correct location, does
fixups, etc

I tried running it from the command line:

EA3131-NXP # bootm 0x31000000
## Booting kernel from Legacy Image at 31000000 ...
   Image Name:   U-Boot 2011.09-00285-gc0d0576 fo
   Image Type:   ARM U-Boot Firmware (uncompressed)
   Data Size:    240496 Bytes = 234.9 kB
   Load Address: 31200000
   Entry Point:  00000000
   Verifying Checksum ... OK
Wrong Image Type for bootm command
ERROR: can't get kernel image!
