Hi, A Gentle reminder for this series.

Intent of these patches is to fix register reads in STIG mode and also use STIG mode while reading flash registers. Currently if you try to read a register while in STIG mode there is no support for ADDR and thus naturally a register never gets read from the flash.

It's an important fix because without this reading flash registers is a problem in some cases. I was unable to get one of the QSPI Flash from Cypress working just because STIG read of registers was not supported. It would be great if we could get this merged for the coming release. -- Thanks and Regards, Dhruva Gole
