This will usually fail to work.

"bootm" perfectly understands about XIP images,  and  allows  you  to
pass the usual bd_info structure and boot commandline paramaters. All
of this will be missing with "go".

This is NOT the only problem. It also misses to set  up  the  reqired
registers  needed  for  the  kernel,  and  ther eis no passing of any
bd_info ot ATAGS or similar data.
