Shutdown U-Boot before starting an OS ...

Some devices, especially the ones doing DMA should be disabled before
giving control to an OS. We take the simple approach here: Just shutdown

hush: Fix quoting ...

This patch removes adding of an additional \ when doing

echo "\""

which gives \" instead of just "

I checked in latest busybox hush and this code is still present there,
but it behaves correctly in busybox due to some other code pathes I
didn't investigate.
If this change has any unwanted side effects feel free to flame on me

[Patch 02/17] U-Boot-V2: Handle case of clock rollover for get_time_ns

get_time_ns does a simplistic delta = cycle_now - cycle_last. It is possible that the h/w counter reached max and reset back to 0.
This patch addresses this issue by checking for rollover condition.

NOTE 1: This does not guarentee that you cannot confuse get_time_ns. You could possibly wait for two reset cycles and then get a messed up value.
To fix that we may need interrupt mode timer tick - something on the lines of jiffies on linux.
NOTE 2: the question of cs->mask is not clear. if the mask is for the tick, then it is better done with (cycle_now & cs->mask) - (cs->cycle_last & cs->mask).
