Embedded Linux Fast Boot: Only 560 milliseconds from reset to shell

[Constantine Shulyupin]

Shalom,

I achieved embedded Linux boot in 560 ms (about a half of a second) on
TI DM365 (ARM 300 MHz) with NAND flash.

Boot log with timestamps Logging starts at 20 ms from reset.

0.000 0.000: DM36x initialization passed!
