In Linux, readl_poll_timeout API already add delay of 1us which is skipped in U-boot. Since, NXP Flexspi U-boot driver is a ported version of Linux driver and U-boot poll_timeout API lacks delay functionality, add 1us delay so as to make controller ready for other transactions.
Can you link me, where does Linux add this delay?
Jagan.
