On Jetson TK1, there's something up with USB. Here's a good run with 
something based on a merge of v2015.0r-rc5 and a merge of 
u-boot-tegra/master from around the end of March:

... and here's u-boot-dm/next

(I notice both those lines have the same device ID rather than one being 
0 and the other 1)

(same issue there, although perhaps this is expected if USB devnum is 
per-controller now?)

Seaboard/Springbank appears to have the same issue. Additionally, the 
flashing process spews a ton of:

ERROR: v7_dcache_inval_range - start address is not aligned - 0x3f77a428
ERROR: v7_dcache_inval_range - stop address is not aligned - 0x3f77ac28

... and despite reporting an error during flash writing, the system 
boots, I don't know if this is anything related to the DM changes or 
something else though; I'll go check.
