[i.MX7D][Yocto 2.1] How to add qspi-nor-xxx-config for QSPI boot

1. I find a file(qspi-nor-macronix-mx25l51245g-config) in mfg tool for i.MX7D demo board.
2. This config file(qspi-nor-macronix-mx25l51245g-config) is needed to use when the device boots from QSPI.
The contents of the file(qspi-nor-macronix-mx25l51245g-config) are as follows:

 

0 /*dqs_loopback=0 or 1*/
0 /*hold_delay=0 to 3*/
0 /*hsphs=0 (Half Speed Phase sampling at non-inverted clock) or 1 (sampling at inverted clock)*/
0 /*hsdly=0 (Half Speed Delay one clk delay) or 1 (two clk cycle delay)*/

c0ffee01 /*tag, QSPI configuration tag, should be 0xc0ffee01*/

Can you tell me how to generate this file when I use the different QSPI?

Thank you.
