while re-testing QSPI_NOR/NAND both didn't work, after few changes from
patchV6 followed by your changes,

now QSPI-NOR started working,  soon will be sending updated patch
version which includes your changes as well as my changes

without affecting both the platforms(TI and Intel).

BTW,  Have you tested QSPI-NAND on your platform ? with our patches.

Thanks! for your review and support.
