QSPI flash memory "N25Q00A" at u-boot and linux for HPS

1

I use Cyclone V SoC.
I would like to use QSPI flash memory “N25Q00A” at u-boot.

There are times when R/W can not be done well.
What kind of setting values are necessary?

I solved this problem on my own.
The cause was that the u-boot driver was not compatible with multi die flash memory.

From the data sheet :
After any READ command is executed, the device will output data from the selected address in the die. After a die boundary is reached, the device will start reading again from the beginning of the same 256Mb die.
