Also, does anyone know what the boot time of Linux typically is on the TS7250? 
The TS7800, for example, is advertised to "Boots Linux in 0.69s from Flash" or 
also says "Linux utility loads FPGA from user file in .6 seconds."  I can find 
descriptions of what the boot sequence is in the 7250 manual... but I can't 
judge how long it takes.

Thanks.
