  Increase the spi-max-frequency of nor flash from 10Mhz to 30Mhz,this improves the
flash raw write speed by 0.9 MB/s to 1.6MB/s and the time taken to write is
get reduced from 36 seconds to 20 seconds.

who are these other people? :-)

I.e. it looks like you're the author of the patch,
and so it should only have your Signed-off-by line.

If Da Xue and dsx724 have tested / reviewed the change, they
should respond individually to the posted patch with
either a "Reviewed-by: ..." or "Tested-by: ..." line.


Thanks
Heiko
